Lunar clockwork
What scientists know for certain is that they need to get precision timekeeping instruments to the moon.

Exactly who pays for lunar clocks, which type of clocks will go, and where they’ll be positioned are all questions that remain up in the air, Gramling said.

“We have to work all of this out,” she said. “I don’t think we know yet. I think it will be an amalgamation of several different things.”

Atomic clocks, Gramling noted, are great for long-term stability, and crystal oscillators have an advantage for short-term stability.
“You never trust one clock,” Gramling added. “And you never trust two clocks.”

Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit.

As for price, an atomic clock worthy of space travel could cost around a few million dollars, according Gramling, with crystal oscillators coming in substantially cheaper.

But, Patla said, you get what you pay for.

“The very cheap oscillators may be off by milliseconds or even 10s of milliseconds,” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.”

A network of clocks on the moon could work in concert to inform the new lunar time scale, just as atomic clocks do for UTC on Earth.

(There will not, Gramling added, be different time zones on the moon. “There have been conversations about creating different zones, with the answer: ‘No,’” she said. “But that could change in the future.”)

The voice of ‘White Lotus’ star Walton Goggins is the lullaby we didn’t know we needed
jumper exchange
While his “White Lotus” character Rick has been the source of some stress this season, Walton Goggins is here to soothe us into a state of dreamy sleep to make up for it.

The actor has partnered with relaxation and meditation app Calm for one of their famed Sleep Stories, lending his smoky voice to a fable titled “The Yard Sale.”

Goggins announced the Sleep Story on his verified Instagram on Tuesday, writing, “A friend once said to me the first question you ask someone shouldn’t be, ‘How are you?’ but rather, ‘How did you sleep last night?’ I agree.”

The post included an excerpt from the story, in which Goggins is heard languidly instructing listeners to relax their bodies and get into bed. “You could even climb into a hammock,” he added. “I wouldn’t do that because I’ve never gracefully got in or out of one.”

In the caption, the actor also wrote that he “wanted to create a Sleep Story that feels dreamlike, helping people slow their minds down by wandering through a yard sale (which happens to be one of my favorite things to do), uncovering hidden treasures.”

“It’s the Walton Goggins version of counting sheep. I hope you enjoy,” he added.

Other celebrities who have read bedtime stories in the hopes of putting audiences to sleep include Dolly Parton and the late Jimmy Stewart, whose voice was featured in a Calm Christmas Sleep Story in 2023 thanks to generative AI technology.

Goggins currently stars on “The White Lotus,” where his character is often the most stressed out and tortured of the ensemble, at one point setting a slew of snakes free.

Space, time: The continual question
If time moves differently on the peaks of mountains than the shores of the ocean, you can imagine that things get even more bizarre the farther away from Earth you travel.

To add more complication: Time also passes slower the faster a person or spacecraft is moving, according to Einstein’s theory of special relativity.

Astronauts on the International Space Station, for example, are lucky, said Dr. Bijunath Patla, a theoretical physicist with the US National Institute of Standards and Technology, in a phone interview. Though the space station orbits about 200 miles (322 kilometers) above Earth’s surface, it also travels at high speeds — looping the planet 16 times per day — so the effects of relativity somewhat cancel each other out, Patla said. For that reason, astronauts on the orbiting laboratory can easily use Earth time to stay on schedule.

For other missions — it’s not so simple.

Fortunately, scientists already have decades of experience contending with the complexities.

Spacecraft, for example, are equipped with their own clocks called oscillators, Gramling said.

“They maintain their own time,” Gramling said. “And most of our operations for spacecraft — even spacecraft that are all the way out at Pluto, or the Kuiper Belt, like New Horizons — (rely on) ground stations that are back on Earth. So everything they’re doing has to correlate with UTC.”
But those spacecraft also rely on their own kept time, Gramling said. Vehicles exploring deep into the solar system, for example, have to know — based on their own time scale — when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes, she added.

For 50 years, scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites, which orbit Earth about 12,550 miles (20,200 kilometers) away — or about one-nineteenth the distance between our planet and the moon.

Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon, Patla said.

“We can easily compare (GPS) clocks to clocks on the ground,” Patla said, adding that scientists have found a way to gently slow GPS clocks down, making them tick more in-line with Earth-bound clocks. “Obviously, it’s not as easy as it sounds, but it’s easier than making a mess.”

President Donald Trump on Thursday blamed the Federal Aviation Administration’s “diversity push” in part for the plane collision that killed 67 people in Washington, DC. But DEI backers, including most top US companies, believe a push for diversity has been good for their businesses.

Trump did not cite any evidence for how efforts to hire more minorities, people with disabilities and other groups less represented in American workforces led to the crash, saying “it just could have been” and that he had “common sense.” But Trump criticized the FAA’s effort to recruit people with disabilities during Joe Biden’s administration, even though the FAA’s Aviation Safety Workforce Plan for the 2020-2029 period, issued under Trump’s first administration, promoted and supported “the hiring of people with disabilities and targeted disabilities.”

It’s not the first time opponents of diversity, equity and inclusion initiatives, or DEI, have said they can kill people. “DEI means people DIE,” Elon Musk said after the California wildfires, criticizing the Los Angeles Fire Department and city and state officials for their efforts to advance diversity in their workforces.

‘We don’t want the American Dream for our kids’: Why this couple left the US for Ecuador with their children four years ago
юрист у військових справах Запоріжжя з мобілізації
They’d never even visited Ecuador before, but Brittany and Blake Bowen, from the United States, decided to move to the South American country in 2021 to give their four children a completely different upbringing.

The Bowens, who were previously based in the state of Washington, have been living in Loja, a small city based in the southern section of the Andes Mountains, ever since, and say that they are in it for the long haul.

“We love this little country,” Brittany tells CNN Travel. “We hope that maybe we’ll have grandkids here one day.”
Before the move, the couple, who’ve been married for nearly 17 years, say that they were becoming increasingly concerned about the pressures placed on children by “modern American society” and wanted to try something new.

“We did not like what we’d seen develop over the course of the last couple decades…” adds Brittany, explaining that they felt that young people in the United States were becoming “more isolated.”

“We weren’t confident that our kids would enjoy the same sort of potential trajectory that previous generations had shared.

“And the more we considered things like that, the more we wondered, ‘Is that even what we want? Do we even want them to be on a fast track to the American Dream?”

The couple were also frustrated with living what they describe as the “standard American life.”

“Long commutes and never enough money,” says Blake. “All those usual problems… I was working in a career that was very time consuming, and took me away from home a lot. So we didn’t want that anymore.”

So why did they choose Ecuador as their “new home”?

“You have a government that is reckless about what is going to happen to Guyana,” said Melinda Janki, an international lawyer in Guyana who is handling several lawsuits against Exxon. It’s pursuing “a supposed course of development that is actually backward and destructive,” she told CNN.

And while plenty of Guyanese people welcome the new oil industry, some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people, many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6% in 2023, with prices of some foods shooting up much more rapidly.

“Since the oil extraction began in Guyana, we have noticed that our cost of living has gone sky high,” said Wintress White, of Red Thread, a non-profit that focuses on improving living conditions for Guyanese women. “The money is not trickling down to the masses,” she told CNN.

CNN contacted President Ali, the Ministry of Natural Resources and the Ministry of Finance for comment but received no response.
Guyana, a former Dutch then British colony which gained independence in 1966, is one of only a handful of countries that is a “carbon sink,” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow.

The country has protected its biodiversity where others have destroyed theirs, President Ali said in a BBC interview last year. In 2009, the country signed an agreement with Norway, which promised Guyana more than $250 million to preserve its 18.5 million hectares, or nearly 46 million acres, of forests.

Ali insists the country can balance climate leadership and fossil fuel exploitation. The new oil wealth will allow Guayana to develop, including building climate adaptations such as sea walls, he has said. He has also pointed to the continued failures of wealthy countries, already grown rich on their own fossil fuels, to help poorer countries with climate finance.

But there are concerns Guyana could fall victim to the “resource curse,” in which vast, new wealth ?can actually make life worse for those who live there.

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
kyberswap
Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.

It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.

Guyana now has the world’s highest expected oil production growth through 2035.

This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.

While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.
Since Exxon’s transformative discovery, Guyana’s government has tightly embraced oil as a route to prosperity. In December 2019, then-President David Granger said in a speech, “petroleum resources will be utilized to provide the good life for all … Every Guyanese will benefit.”

It’s a narrative that has continued under current President Mohamed Irfaan Ali, who says new oil wealth will allow Guyana to develop better infrastructure, healthcare and climate adaptation.
