Finally, a Fun Conspiracy Theory: Roy Kent on 'Ted Lasso' Is CGI

I know Roy Kent is played by Brett Goldstein, real person.Also, they’re maybe tired of having to wait a week for new episodes rather than binge-watching them.

Computer Scientists Find a Key Research Algorithm's Limits

Computer Scientists Find a Key Research Algorithm's Limits

You know you can find an answer, because there are more people than houses, but it may take some looking (especially if they don’t share a last name).This question belongs to a complexity class called TFNP, short for “total function nondeterministic polynomial.” It is the collection of all computational problems that are guaranteed to have solutions and whose solutions can be checked for correctness quickly.

How to Survive a Killer Asteroid

How to Survive a Killer Asteroid

Then, in the early 1900s, astronomers like Russia’s Nikolai Morozov* began observing newly developed high explosives and made a rather startling discovery: Large explosions differ from thrown rocks in a number of ways, but most ominously—at least for our species’ continued existence—they leave circular craters regardless of their angle of impact.

Quantum Mischief Rewrites the Laws of Cause and Effect

Quantum Mischief Rewrites the Laws of Cause and Effect

That’s changing as physicists contemplate the new quantum switch experiments, as well as related thought experiments in which Alice and Bob face causal indefiniteness created by the quantum nature of gravity.Lucien Hardy originated the study of indefinite causality as a route to understanding the quantum nature of gravity.

Don’t Tell Einstein, but Black Holes Might Have ‘Hair’

Don’t Tell Einstein, but Black Holes Might Have ‘Hair’

“We would expect that the gravitational signal we would see would be quite different from ordinary black holes that are not extremal,” said Khanna.

How Universes Might Bubble Up and Collide

How Universes Might Bubble Up and Collide

When space is as empty as possible and can’t possibly lose more energy, it exists in what physicists call a “true” vacuum state.Since they can’t prod actual vacuum bubbles in the multiverse, physicists have sought digital and physical analogs of them.

The Black Hole Information Paradox Comes to an End

The Black Hole Information Paradox Comes to an End

Hawking and others sought to describe matter in and around black holes using quantum theory, but they continued to describe gravity using Einstein’s classical theory—a hybrid approach that physicists call “semiclassical.” Although the approach predicted new effects at the perimeter of the hole, the interior remained strictly sealed off.

Testing Won’t Save Us From Covid-19

Testing Won’t Save Us From Covid-19

If our Covid tests were only cheap enough to make, and prompt enough in delivering results, according to Harvard epidemiologist Michael Mina, then we could “quickly contain and end this terrible plague.” Let’s call it the Theory of the Magic Testing Cure: Give the masses inexpensive, instant, at-home diagnostics, and everyone who is infectious will know to put themselves in quarantine.

Mathematical ‘Hocus-Pocus’ Saved Particle Physics

Mathematical ‘Hocus-Pocus’ Saved Particle Physics

To theorists puzzling over the physical meaning of renormalization, QED hinted that the electron had two charges: a theoretical charge, which was infinite, and the measured charge, which was not.

That Racist Kamala Harris Birther Conspiracy Is Nothing New

That Racist Kamala Harris Birther Conspiracy Is Nothing New

If you take social media at its word, Senator Kamala Harris , the presumptive vice presidential nominee for the Democratic Party, is actor Jussie Smollett’s aunt, thinks white lab coats and Joe Biden are racist, would sign an executive order to confiscate your guns, and is Caucasian.

The Rise and Spread of a 5G Coronavirus Conspiracy Theory

Van Kerckhoven didn’t just claim that 5G was dangerous: He also said it might be linked to coronavirus.

Valve Swears Half-Life: Alyx Is Actually, Legitimately Done

So as the release date for the new VR experience Half-Life: Alyx approaches, and other high-profile games face delays , it's understandable fans might be worried.Every year, the Game Developers Conference releases a survey on the state of videogames, tabulating results from all across the industry.

At Last, Physicists Confirm the Fastest Way to Board a Plane

At Last, Physicists Confirm the Fastest Way to Board a Plane

It's counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process and less time before takeoff, according to a new paper in Physical Review E.

The Physics Nobel Goes to the Big Bang and Exoplanets

The Physics Nobel Goes to the Big Bang and Exoplanets

This year’s award goes to a Canadian physicist, James Peebles, whose theoretical work underpins the current understanding of the universe’s beginnings, and to two Swiss astronomers, Michel Mayor and Didier Queloz, who discovered the first planet orbiting a Sun-like star .

Are We All Wrong About Black Holes?

Are We All Wrong About Black Holes?

In the early 1970s, people studying general relativity, our modern theory of gravity , noticed rough similarities between the properties of black holes and the laws of thermodynamics.

Where Do Supermassive Black Holes Come From?

Where Do Supermassive Black Holes Come From?

This speed limit can theoretically be exceeded if the matter is collapsing fast enough; the Basu and Das model suggests black holes were accreting matter at three times the Eddington rate for as long as the chain reaction was happening.

Astronomers Think They Can Explain Mysterious Cosmic Bursts

Astronomers Think They Can Explain Mysterious Cosmic Bursts

“In just very general terms, this makes a ton of sense,” said James Cordes , an astrophysicist at Cornell University, adding that while further details still need to be worked out, “I would say it’s a good horse to bet on.” What the astronomers really like, though, is that Metzger’s theory generates very specific predictions for what future FRBs should look like, predictions that will soon be put to make-or-break tests.

Is the Universe a Hologram? Maybe! This Math Trick Shows How

Is the Universe a Hologram? Maybe! This Math Trick Shows How

There is “tantalizing evidence,” said Xi Dong of the University of California, Santa Barbara, who led the research, that the new model is a piece of “a unified framework for quantum gravity in de Sitter [space].” Dong and co-authors Eva Silverstein of Stanford University and Gonzalo Torroba of the Bariloche Atomic Center in Argentina constructed a hologram of dS space by taking two AdS universes, cutting them, warping them and gluing their boundaries together.

The Peculiar Math That Could Underlie the Laws of Nature

The Peculiar Math That Could Underlie the Laws of Nature Cohl Furey, a mathematical physicist at the University of Cambridge, is finding links between the Standard Model of particle physics and the octonions, numbers whose multiplication rules are encoded in a triangular diagram called the Fano plane.

The Evolutionary Importance of Neutral vs. Adaptive Genes

The Evolutionary Importance of Neutral vs. Adaptive Genes

For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.Motoo Kimura proposed in 1968 that most mutations might be neutral in effect rather than beneficial or harmful, and that shifts in the frequency of these neutral mutations dominated evolutionary change at the genomic level.Annual ReviewsBut in 1968, the famed population geneticist Motoo Kimura resisted the adaptationist perspective with his neutral theory of molecular evolution.
