The U.S. Food and Drug Administration (FDA) on Wednesday approved Pfizer Inc.’s respiratory syncytial virus (RSV) vaccine for older adults, making it the second shot against the common respiratory disease that can be fatal for seniors.

The approval comes less than a month after the FDA approved a similar shot by rival GSK PLC. Pfizer’s vaccine was approved for people aged 60 and older, the company said, the same age group as GSK’s shot.

In a late-stage study, Pfizer’s vaccine, to be sold under the brand name Abrysvo, was 67% effective among those aged 60 and older with two or more symptoms of RSV, and 85.7% effective against severe illness defined by three or more symptoms.

Pfizer and GSK have said they expect a multibillion-dollar market for RSV vaccines.

Vaccine available in third quarter

The company expects to make the vaccine available during the third quarter, ahead of the next RSV season, once the U.S. Centers for Disease Control and Prevention (CDC) signs off on its use.

The CDC’s advisory committee is expected to meet in June to discuss the vaccines, including who should receive them and how often.

Pfizer did not disclose a price for the vaccine. It said the price would be value-based to support routine vaccination for the recommended age group for the shots.

If the vaccine is recommended by the CDC for routine use, it will be widely available at no out-of-pocket cost for most older Americans covered by the government Medicare health plan, the company said.

RSV usually causes mild cold-like symptoms but also can lead to serious illness and hospitalization. It is estimated to be responsible for 14,000 deaths in adults aged 65 and older in the United States annually, according to government data.

Seeking OK for pregnant women

Pfizer also is seeking FDA approval for its RSV vaccine to prevent the disease in infants by inoculating pregnant women. It could become the first RSV vaccine available to protect babies, who are among those at greatest risk for severe illness.

The shot received backing by the agency’s panel of outside experts earlier this month for use in pregnant women.

The company has said it is ready to launch its RSV vaccine for both older adults and pregnant women in the United States and Europe this year.

Moderna Inc. has said it expects to seek approval for its RSV vaccine this quarter for those aged 60 and older.

Sanofi and partner AstraZeneca PLC in November gained European marketing authorization for their antibody treatment nirsevimab for preventing RSV in newborns and infants. It is currently under FDA review.

Canada will soon require that health warnings be printed on individual cigarettes and cigars in a further crackdown on smoking, the country’s addictions minister announced Wednesday.

The messaging, to be phased in starting August 1, will include lines such as “Poison in every puff,” “Tobacco smoke harms children” and “Cigarettes cause cancer.”

Addictions Minister Carolyn Bennett said tobacco use continues to kill 48,000 Canadians each year. The new labeling rule is a world first, she said, although Britain has flirted with a similar regulation.

“This bold step will make health warning messages virtually unavoidable and, together with updated graphic images displayed on the package, will provide a real and startling reminder of the health consequences of smoking,” Bennett said.

The Canadian government noted that some young people, who are particularly susceptible to the risk of tobacco dependence, start smoking after being given a single cigarette rather than a pack labeled with health warnings.

In 2000, Canada became the first country to order graphic warnings on packs of cigarettes — including grisly pictorials of diseased hearts and lungs — to raise awareness of the health hazards associated with tobacco use.

Smoking has been trending down over the past two decades.

Ottawa aims to further reduce the number of smokers in the country to 5% of the population, or about 2 million people, by 2035, from about 13% currently.

According to government data, almost half of the country’s health care costs are linked to substance use.

Scientists have expanded the search for technologically advanced extraterrestrial civilizations by monitoring a star-dense region toward the core of our galaxy for a type of signal that could be produced by potential intelligent aliens that until now has been ignored. 

Efforts to detect alien technological signatures previously have focused on a narrowband radio signal type concentrated in a limited frequency range or on single unusual transmissions. The new initiative, scientists said Wednesday, focuses on a different signal type that perhaps could enable advanced civilizations to communicate across the vast distances of interstellar space. 

These wideband pulsating signals for which the scientists are monitoring feature repetitive patterns – a series of pulses repeating every 11 to 100 seconds and spread across a few kilohertz, similar to pulses used in radar transmission. The search involves a frequency range covering a bit less than a tenth the width of an average FM radio station. 

“The signals searched in our work would belong to the category of deliberate ‘we are here’ type beacons from alien worlds,” said Akshay Suresh, a Cornell University graduate student in astronomy and lead author of a scientific paper published in The Astronomical Journal describing the new effort. 

“Aliens may possibly use such beacons for galaxy-wide communications, for which the core of the Milky Way is ideally placed. One may imagine aliens using such transmissions at the speed of light to communicate key events, such as preparations for interstellar migration before the explosive death of a massive star,” Suresh added. 

The effort, called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), is a collaboration between Cornell, the SETI Institute research organization and Breakthrough Listen, a $100 million initiative to search for advanced extraterrestrial life. 

Diverse exploration called crucial

“In the realm of searching for extraterrestrial intelligence, or SETI, we embark on a journey to detect signals from technologically advanced extraterrestrial civilizations,” said astronomer and study co-author Vishal Gajjar of the SETI Institute and University of California at Berkeley. 

“However, the nature of these signals remains a mystery, leaving us uncertain about their specific characteristics. Hence, it becomes crucial to explore a diverse array of signals that are unlikely to occur naturally in the cosmic environment,” Gajjar added. 

Using a ground-based radio telescope in West Virginia, BLIPSS has focused upon a sliver of the sky less than 1/200th of the area covered by the moon, stretching toward the center of the Milky Way roughly 27,000 light-years away. A light-year is the distance light travels in a year, 9.5 trillion kilometers. 

This area contains about 8 million stars, Suresh said. If extraterrestrial life forms exist, they presumably would populate rocky planets orbiting in what is called the habitable zone, or Goldilocks zone, around a star – not too hot and not too cold. 

The scientists in the various monitoring efforts passively scan for signals of alien beings and do not actively send their own signals advertising our presence on Earth. 

“In my opinion, transmission of ‘we are here’ type beacons comes with the danger of potentially inviting aliens with unknown intentions to the Earth,” Suresh said. 

Prudent approach

Deliberate transmissions to potential aliens from Earth should be considered only if by global consensus humankind deems it safe and appropriate, Gajjar said. 

“In my personal opinion, as a relatively young species in the grand cosmic scale, it would be prudent for us to focus on listening and investigating before embarking on deliberate transmissions,” Gajjar said. “Furthermore, it is crucial to recognize that sending signals on behalf of the entire Earth raises political and ethical considerations. Presently, it would not be appropriate for a single country or entity to make decisions on behalf of the entire planet.” 

No aliens have yet been detected in the monitoring efforts. 

“Thus far, we have not come across any definitive evidence. However, it’s important to note that our exploration has been limited to a relatively small parameter space,” Gajjar said.

Operations to salvage 1.1 million barrels of oil from a decaying tanker moored off Yemen’s coast will soon begin after a technical support ship arrived on site on Tuesday, the United Nations said.

U.N. officials have been warning for years that the Red Sea and Yemen’s coastline was at risk as the Safer tanker could spill four times as much oil as the 1989 Exxon Valdez disaster off Alaska.

The Ndeavor tanker, with a technical team from Boskalis/SMIT, is in place at the Safer tanker off the coast of Yemen’s Ras Isa, the U.N. Humanitarian Coordinator in Yemen David Gressley said on Twitter from on board the Ndeavor.

The war in Yemen caused suspension of maintenance operations on the Safer in 2015. The U.N. has warned its structural integrity has significantly deteriorated and it is at risk of exploding.

The U.N. launched a fundraising drive, even starting a crowdfunding campaign, to raise the $129 million needed to remove the oil from the Safer and transfer it to a replacement tanker, the Nautica, which set sail from China in early April.

The salvage operation cannot be paid for by the sale of the oil because it is not clear who owns it, the U.N. has said.

“Work at sea will start very soon. Additional funding is still important to finish the process,” the U.N said on its Yemen Twitter account.

Yemen has been mired in conflict since the Iran-aligned Houthi group ousted the government from the capital Sanaa in late 2014. A Saudi Arabia-led military coalition intervened in 2015 aiming to restore the government.

Peace initiatives have seen increased momentum since Riyadh and Tehran in March agreed to restore diplomatic ties severed in 2016.

Health care providers in Kenya’s Dadaab refugee camp say an ongoing cholera outbreak is becoming a looming catastrophe. Doctors Without Borders has described the six-month-long cholera outbreak as the worst yet, amid an influx of new refugees from Somalia.

Medecins Sans Frontieres, popularly known as Doctors Without Borders, told a news conference Tuesday that a cholera outbreak the Dadaab camp is approaching epidemic proportions and that urgent attention in the areas of water and sanitation is needed. Dr. Nitya Udayraj is the medical coordinator. 

“The humanitarian conditions there are already at its limit. An outbreak like cholera, like measles, is literally the last stroke that will bring it to the breaking point,” said Dr. Nitya Udayraj, MSF’s medical coordinator. “Which is why today we want to bring focus that the humanitarian situation is already precarious. … We would like to bring attention that after six months, the outbreak is still continuing. It is not normal.”

The cholera outbreak hit East Africa’s largest refugee camp last November. At least five people have died since then. The Dadaab complex in Kenya’s northeastern region is home to over 300,000 refugees, most from neighboring Somalia.

Their numbers have exceeded capacity due to the extended drought in Somalia. At least 67,000 more refugees arrived in the camp last year, according to national data, putting pressure on already limited resources. Doctors Without Borders’ country director Hassan Maiyaki said sanitary conditions are dire.

“Today, according to humanitarian organizations working in the camps, almost half of the camp population has no access to functional latrines, leading to open defecation in and around the camp, which raises the risk of disease outbreaks.”

Kenya’s Ministry of Health conducted cholera vaccinations at the camp, but the doctors say curbing the outbreak remains elusive without sanitation and hygiene intervention.

An International Atomic Energy Agency team arrived in Tokyo on Monday for a final review before Japan begins releasing massive amounts of treated radioactive water into the sea from the wrecked Fukushima nuclear plant, a plan that has been strongly opposed by local fishing communities and neighboring countries. 

The team, which includes experts from 11 countries, will meet with officials from the government and the plant operator, Tokyo Electric Power Company Holdings, and visit the Fukushima Daiichi nuclear power plant during their five-day visit, the economy and industry ministry said. 

Japan announced plans in April 2021 to gradually release the wastewater following further treatment and dilution to what it says are safe levels. The release is expected to begin within a few months after safety checks by Japanese nuclear regulators of the newly constructed water discharge facility and a final report by IAEA expected in late June. 

The plan has faced fierce protests from local fishing communities concerned about safety and reputational damage. Nearby countries, including South Korea, China and Pacific Island nations, have also raised safety concerns. 

SEE ALSO: A related video by VOA’s Jessica Stone

Japan sought IAEA’s assistance in ensuring the release meets international safety standards and to gain the understanding of other countries. 

Japanese officials say the water will be treated to legally releasable levels and further diluted with large amounts of seawater. It will be gradually released into the ocean over decades through an undersea tunnel, making it harmless to people and marine life, they say. 

Some scientists say the impact of long-term, low-dose exposure to radionuclides is unknown and the release should be delayed. 

Japan’s government has stepped up campaigns in Japanese media and at food fairs to promote the safety of seafood from Fukushima, while providing regular briefings to foreign governments including South Korea and members of the Pacific Islands Forum. 

A massive March 11, 2011, earthquake and tsunami destroyed the Fukushima Daiichi nuclear plant’s cooling systems, causing three reactors to melt and releasing large amounts of radiation. Water used to cool the reactor cores accumulated in about 1,000 tanks at the plant which will reach their capacity in early 2024. 

Japanese officials say the water stored in the tanks needs to be removed to prevent accidental leaks in case of another disaster and to make room for the plant’s decommissioning.

The United Arab Emirates unveiled plans Monday to send a spaceship to explore the solar system’s main asteroid belt, the latest space project by the oil-rich nation after it launched the successful Hope spacecraft to Mars in 2020. 

Dubbed the Emirates Mission to the Asteroid Belt, the project aims to develop a spacecraft in the coming years and then launch it in 2028 to study various asteroids. 

“This mission is a follow up and a follow on the Mars mission, where it was the first mission to Mars from the region,” said Mohsen Al Awadhi, program director of the Emirates Mission to the Asteroid Belt. “We’re creating the same thing with this mission. That is, the first mission ever to explore these seven asteroids in specific and the first of its kind when it’s looked at from the grand tour aspect.” 

The UAE became the first Arab country and the second country ever to successfully enter Mars’ orbit on its first try when its Hope probe reached the red planet in February 2021. The craft’s goals include providing the first complete picture of the Martian atmosphere and its layers and helping answer key questions about the planet’s climate and composition. 

If successful, the newly announced spacecraft will soar at speeds reaching 33,000 kilometers (20,500 miles) per hour on a seven-year journey to explore six asteroids. It will culminate in the deployment of a landing craft onto a seventh, rare “red” asteroid that scientists say may hold insight into the building blocks of life on Earth. 

Organic compounds like water are crucial constituents of life and have been found on some asteroids, potentially delivered through collisions with other organic-rich bodies or via the creation of complex organic molecules in space. Investigating the origins of these compounds, along with the possible presence of water on red asteroids, could shed light on the origin of Earth’s water, thereby offering valuable insights into the genesis of life on our planet. 

The endeavor is a significant milestone for the burgeoning UAE Space Agency, established in 2014, as it follows up on its success in sending the Amal, or “Hope,” probe to Mars. The new journey would span a distance over ten times greater than the Mars mission. 

The explorer is named MBR after Dubai’s ruler Sheikh Mohammed bin Rashid Al Maktoum, who also serves as the vice president and prime minister of the hereditarily ruled UAE. It will first make its way toward Venus, where the planet’s gravitational pull will slingshot it back past the Earth and then Mars. 

The craft will eventually reach the asteroid belt, flying as close as 150 kilometers (93 miles) to the celestial boulders and covering a total distance of 5 billion kilometers (around 3 billion miles). 

In October 2034, the craft is expected to make its final thrust to the seventh and last asteroid, named Justitia, before deploying a lander over a year later. Justitia, believed to be one of only two known red asteroids, is thought to potentially have a surface laden with organic substances. 

“It’s one of the two reddest objects in the asteroid belt, and scientists don’t really understand why it’s so red,” said Hoor AlMaazmi, a space science researcher at the UAE space agency. “There are theories about it being originally from the Kuiper Belt and where there’s much more red objects there. So that’s one thing that we can study because it has the potential for it to be water rich as well.” 

The MBR Explorer will deploy a landing craft to study the surface of Justitia that will be fully developed by private UAE start-up companies. It may lay the groundwork for possible future resource extraction from asteroids to eventually support extended human missions in space — and maybe even the UAE’s ambitious goal of building a colony on Mars by 2117. 

“We have identified different key areas that we want startups in the private sector to be part of, and we will engage with them through that,” said Al Awadhi. 

“We understand that the knowledge we have in the UAE is, you know, still being built. We will provide these startups with the knowledge they need.”

China’s burgeoning space program plans to place astronauts on the moon before 2030 and expand the country’s orbiting space station, officials said Monday.

Monday’s announcement comes against the backdrop of a rivalry with the U.S. for reaching new milestones in outer space, reflecting their competition for influence on global events.

That has conjured up memories of the space race between the U.S. and the former Soviet Union in the 1960s and 1970s, although American spending, supply chains and capabilities are believed to give it a significant edge over China, at least for the present.

The U.S. aims to put astronauts back on the lunar surface by the end of 2025 as part of a renewed commitment to crewed missions, aided by private sector players such as SpaceX and Blue Origin.

The deputy director of China’s space agency confirmed the twin objectives at a news conference but gave no specific dates.

The agency also introduced three astronauts who will head to the country’s space station in a launch scheduled for Tuesday morning. They’ll replace a crew that’s been on the orbiting station for six months.

China is first preparing for a “short stay on the lunar surface and human-robotic joint exploration,” Deputy Director of the Chinese Manned Space Agency Lin Xiqiang told reporters at the rare briefing by the military-run program.

“We have a complete near-Earth human space station and human round-trip transportation system,” complemented by a process for selecting, training and supporting new astronauts, he said. A schedule of two crewed missions a year is “sufficient for carrying out our objectives,” Lin said.

The Tiangong space station was said to have been finished in November when the third section was added.

A fourth module will be launched “at an appropriate time to advance support for scientific experiments and provide the crew with improved working and living conditions,” Lin said.

The trio being launched aboard the Shenzhou 16 craft will overlap briefly with the three astronauts who have lived on the station for the previous six months conducting experiments and assembling equipment inside and outside the vehicle.

The fresh crew includes a civilian for the first time. All previous crew members have been in the People’s Liberation Army, the military wing of the country’s ruling Communist Party.

Gui Haichao, a professor at Beijing’s top aerospace research institute, will join mission commander Jing Haipeng and spacecraft engineer Zhu Yangzhu as the payload expert.

Speaking to media at the launch site outside the northwestern city of Jiuquan, Jing said the mission marked “a new stage of application and development,” in China’s space program.

“We firmly believe that the spring of China’s space science has arrived, and we have the determination, confidence, and ability to resolutely complete the mission,” said Jing, a major general who has made three previous space flights.

China’s first manned space mission in 2003 made it the third country after the USSR and the U.S. to put a person into space.

China built its own space station after it was excluded from the International Space Station, largely due to U.S. objections over the Chinese space programs’ intimate ties to the PLA.

Space is increasingly seen as a new area of competition between China and the United States — the world’s two largest economies and rivals for diplomatic and military influence — one a highly centralized, one-party state, the other a democracy where the partisan divide largely evaporates over the issues of relations with China and space exploration.

The astronauts NASA sends to the moon by the end of 2025 will aim for the south pole where permanently shadowed craters are believed to be packed with frozen water.

Plans for permanent crewed bases on the moon are also being considered by both countries, raising questions about rights and interests on the lunar surface. U.S. law tightly restricts cooperation between the two countries’ space programs and while China says it welcomes foreign collaborations, those have thus far been limited to scientific research.

Speaking Monday afternoon in Jiuquan, the technology director of the Chinese crewed space flight agency, Li Yingliang, said China hoped for more international collaboration, including with the U.S.

“Our country’s consistent stance is that as long as the goal is to utilize space for peaceful purposes, we are willing to cooperate and communicate with any country or aerospace organization,” Li said.

“Personally, I regret that the U.S. Congress has relevant motions banning cooperation in aerospace between the U.S. and China. I very much regret that personally,” he said.

In addition to their lunar programs, the U.S. and China have also landed rovers on Mars and Beijing plans to follow the U.S. in landing a spacecraft on an asteroid.

Other countries and organizations ranging from the India and the United Arab Emirates to Israel and the European Union are also planning lunar missions.

The U.S. sent six crewed missions to the moon between 1969 and 1972, three of which involved the use of a drivable lunar rover that China says it is now developing with tenders in the private sector.

While America currently operates more spaceports and has a far wider network of international and commercial partners than China, the Chinese program has proceeded in a steady and cautious manner reflecting the county’s vast increase in economic power and global influence since the 1980s.

The mpox health emergency has ended, but U.S. health officials are aiming to prevent a repeat of last year’s outbreaks.

Mpox infections exploded early in the summer of 2022 in the wake of Pride gatherings. More than 30,000 U.S. cases were reported last year, most of them spread during sexual contact between gay and bisexual men. About 40 people died.

With Pride events planned across the country in the coming weeks, health officials and event organizers say they are optimistic that this year infections will be fewer and less severe. A bigger supply of vaccine, more people with immunity and readier access to a drug to treat mpox are among the reasons.

But they also worry that people may think of mpox as last year’s problem.

“Out of sight, out of mind,” said Dr. Demetre Daskalakis, who is advising the White House on its mpox response. “But we are beating the drum.”

Last week, the Centers for Disease Control and Prevention issued a health alert to U.S. doctors to watch for new cases. On Thursday, the agency published a modeling study that estimated the likelihood of mpox resurgence in 50 counties that have been the focus of a government campaign to control sexually transmitted diseases.

The study concluded that 10 of the counties had a 50% chance or higher of mpox outbreaks this year. The calculation was based largely on how many people were considered at high risk for infection and what fraction of them had some immunity through vaccination or previous infection.

At the top of the list are Jacksonville, Florida; Memphis, Tennessee; and Cincinnati — cities where 10% or fewer of the people at highest risk were estimated to have immunity. Another 25 counties have low or medium immunity levels that put them at a higher risk for outbreaks.

The study had a range of limitations, including that scientists don’t know how long immunity from vaccination or prior infections lasts.

So why do the study? To warn people, said Dr. Chris Braden, who heads the CDC’s mpox response.

“This is something that is important for jurisdictions to promote prevention of mpox, and for the population to take note — and take care of themselves. That’s why we’re doing this,” he said.

Officials are trying to bring a sense of urgency to a health threat that was seen as a burgeoning crisis last summer but faded away by the end of the year.

Formerly known as monkeypox, mpox is caused by a virus in the same family as the one that causes smallpox. It is endemic in parts of Africa, where people have been infected through bites from rodents or small animals but was not known to spread easily among people.

Cases began emerging in Europe and the U.S. about a year ago, mostly among men who have sex with men, and escalated in dozens of countries in June and July. The infections were rarely fatal, but many people suffered painful skin lesions for weeks.

Countries scrambled to find a vaccine or other countermeasures. In late July, the World Health Organization declared a health emergency. The U.S. followed with its own in early August.

But then cases began to fall, from an average of nearly 500 a day in August to fewer than 10 by late December. Experts attributed the decline to several factors, including government measures to overcome a vaccine shortage and efforts in the gay and bisexual community to spread warnings and limit sexual encounters.

The U.S. emergency ended in late January, and the WHO ended its declaration earlier this month.

Indeed, there is a lower sense of urgency about mpox than last year, said Dan Dimant, a spokesman for NYC Pride. The organization anticipates fewer messages about the threat at its events next month, though plans could change if the situation worsens.

There were long lines to get shots during the height of the crisis last year, but demand faded as cases declined. The government estimates that 1.7 million people — mostly men who have sex with men — are at high risk for mpox infection, but only about 400,000 have gotten the recommended two doses of the vaccine.

“We’re definitely not where we need to be,” Daskalakis said, during an interview last week at an STD conference in New Orleans.

Some see possible storm clouds on the horizon.

Cases emerged this year in some European countries and South Korea. On Thursday, U.K. officials said an uptick in mpox cases in London in the last month showed that the virus was not going away.

Nearly 30 people, many of them fully vaccinated, were infected in a recent Chicago outbreak. (As with COVID-19 and flu shot, vaccinated people can still get mpox, but they likely will have milder symptoms, officials say.)

Dr. Joseph Cherabie, associate medical director of the St. Louis County Sexual Health Clinic, said people from the area travel to Chicago for events, so outbreaks there can have ripple effects elsewhere.

“We are several weeks behind Chicago. Chicago is usually our bellwether,” Cherabie said.

Chicago health officials are taking steps to prevent further spread at an “International Mr. Leather” gathering this weekend.

Event organizers are prominently advising attendees to get vaccinated. Chicago health officials put together social media messages, including one depicting three candles and a leather paddle that reads: “Before you play with leather or wax get yourself the mpox vax.”

Britain’s health minister, Steve Barclay, said on Sunday that the government would not negotiate on pay with the nurses’ union, as the threat of further strikes looms.

The government’s offer, which includes a one-off payment equivalent to 2% of salaries in the 2022/23 financial year and a 5% pay raise for 2023/24, was rejected by the members of the Royal College of Nursing in April.

When asked by Sky News whether the government would resume talks with the union, Barclay said, “Not on the amount of pay.”

The union is already balloting its 300,000 members on further strike action over the next six months.

The union did not immediately respond to Reuters’ request for a comment on Barclay’s remarks on Sunday. It has said that the government must pay National Health Service staff “fairly.”

The relationship between the union, which has staged multiple strikes that have disrupted patient care, and the government became strained in late April when the health department limited the length of a strike after legal action against the RCN.

When Thomas Hertog was first summoned to Stephen Hawking’s office in the late 1990s, there was an instant connection between the young Belgian researcher and the legendary British theoretical physicist.

“Something clicked between us,” Hertog said.

That connection would continue even as Hawking’s debilitating disease ALS robbed him of his last ways to communicate, allowing the pair to complete a new theory that aims to turn how science looks at the universe on its head.

The theory, which would be Hawking’s last before his death in 2018, has been laid out in full for the first time in Hertog’s book “On the Origin of Time,” published in the UK last month.

In an interview with AFP, the cosmologist spoke about their 20-year collaboration, how they communicated via facial expression, and why Hawking ultimately decided his landmark book “A Brief of History of Time” was written from the wrong perspective.

The ‘designed’ universe

During their first meeting at Cambridge University in 1998, Hawking wasted no time in bringing up the problem bothering him.

“The universe we observe appears designed,” Hawking told Hertog, communicating via a clicker connected to a speech machine.

Hertog explained that “the laws of physics — the rules on which the universe runs — turn out to be just perfect for the universe to be habitable, for life to be possible.”

This remarkable string of good luck stretches from the delicate balance that makes it possible for atoms to form molecules necessary for chemistry to the expansion of the universe itself, which allows for vast cosmic structures such as galaxies.

One “trendy” answer to this problem has been the multiverse, an idea that has recently become popular in the movie industry, Hertog said.

This theory explains away the seemingly designed nature of the universe by making it just one of countless others — most of which are “crap, lifeless, sterile,” the 47-year-old added.

But Hawking realized the “great mire of paradoxes the multiverse was leading us into,” arguing there must be a better explanation, Hertog said.

Outsider’s perspective

A few years into their collaboration, “it began to sink in” that they were missing something fundamental, Hertog said.

The multiverse and even “A Brief History of Time” were “attempts to describe the creation and evolution of our universe from what Stephen would call a ‘God’s eye perspective’,” Hertog said.

But because “we are within the universe” and not outside looking in, our theories cannot be decoupled from our perspective, he added.

“That was why (Hawking) said that ‘A Brief History of Time’ is written from the wrong perspective.”

For the next 15 years, the pair used the oddities of quantum theory to develop a new theory of physics and cosmology from an “observer’s perspective.”

But by 2008, Hawking had lost the ability to use his clicker, becoming increasingly isolated from the world.

“I thought it was over,” Hertog said.

Then the pair developed a “somewhat magical” level of non-verbal communication that allowed them to continue working, he said.

Positioned in front of Hawking, Hertog would ask questions and look into the physicist’s eyes.

“He had a very wide range of facial expressions, ranging from extreme disagreement to extreme excitement,” he said.

“It’s impossible to disentangle” which parts of the final theory came from himself or Hawking, Hertog said, adding that many of the ideas had been developed between the pair over the years.

‘One grand evolutionary process’

Their theory is focused on what happened in the first moments after the Big Bang.

Rather than an explosion that followed a pre-existing set of rules, they propose that the laws of physics evolved along with the universe.

This means that if you turn back the clock far enough, “the laws of physics themselves begin to simplify and disappear,” Hertog said.

“Ultimately, even the dimension of time evaporates.”

Under this theory, the laws of physics and time itself evolved in a way that resembles biological evolution — the title of Hertog’s book is a reference to Darwin’s “On the Origin of Species.”

“What we’re essentially saying is that (biology and physics) are two levels of one grand evolutionary process,” Hertog said.

He acknowledged that it is difficult to prove this theory because the first years of the universe remain “hidden in the mist of the Big Bang.”

One way to lift this veil could be by studying gravitational waves, ripples in the fabric of space time, while another could be via quantum holograms constructed on quantum computers, he said.
