This New Result Changes What We Know About The Butterfly Effect

The butterfly effect is much stranger than most people think, and the famous line about a butterfly in Brazil isn't what Lorenz actually meant. A group of researchers has now worked out that quantum physics puts a hard wall on weather prediction, at 129 days. Not difficult after that. Impossible. And this has implications far beyond the weather forecast because chaos enters in everything from

AI Is Taking Over Physics and Nobody Talks About It

Artificial intelligence has eaten mathematics. In the past few months alone it turned up a counterexample to a conjecture open since 1939, disproved a thirty-year-old result, and made real progress on the Riemann hypothesis. Young mathematicians are somewhere between depression and anger about it. Physics is next, and almost nobody is talking about it. Let's take a look.

Quantum Computing Failure Now Obvious

Quantum computing was supposed to be the next big thing, and for years the companies building it kept promising commercial payoffs were just around the corner and possible already with small, noisy devices (NISQs). Google, IBM, IonQ, they all gave dates. None of them delivered. So why is the industry more optimistic today than ever? Let's take a look.

New Universes Can Form Inside Dying Stars, Physicists Show

Could our universe have been born inside a collapsing star? That idea recently made headlines, and I got a lot of questions about it. The paper behind them describes a new solution to Einstein's equations in which a collapsing star expands on the inside and never forms a black hole. Let's take a look.

Alien Spacecraft Are On the Moon, Astronomers Claim. Seriously now?

A group of astronomers say they've spotted more than twenty giant unidentified objects racing around the Moon, some of them forty kilometres across, and that the Moon serves as a base for them. The daily mail loved it. My bullshit meter did not survive it. But underneath all this nonsense there's a serious question that almost nobody is looking into. Let's take a look.

Two Dimensions of Time Explain Quantum Physics, Physicist Argues

You've probably heard that quantum mechanics is spooky, that measuring one particle instantly affects another across any distance. A physicist now says there's a reason: the universe doesn't have one dimension of time, but two. It sounds absurd, but he's got the maths and even a way to test it. Genius or nonsense? Let's take a look.

Neuroscientists Have Been Misreading Brain Scans for Decades

Neuroscientists have long assumed that when a brain region becomes more active, more blood flows to it. That assumption is the entire basis of functional magnetic resonance imaging. A new paper now says it's wrong for about 40% of the signals, and it isn't the only recent study to find that a lot of what we thought we knew about the brain rests on bad measurements. Let's take a look.

Dunning Kruger Effect Wrong, Scientists Claim

The dumber you are, the more certain you are that you aren't. That's the Dunning-Kruger effect, and it's been used to explain everything from bad politicians to the state of social media. Now psychologists have gone back to the biggest dataset we have and come out with the opposite conclusion. But there's a reason both sides can look at the same dots and see the opposite thing. Let's take a look.
