Einstein Refused to Believe This, But It Could Explain the Universe
A physicist proposes that quantum uncertainty affects the entire universe: we cannot both know how large the universe is and how fast it is expanding.

Neuroscience’s Case Against Free Will Is Falling Apart
In 1983 Benjamin Libet found that brain activity predicts your movements before you are aware of deciding to move. The result has been reproduced many times, and it has been used ever since to argue that free will is an illusion. Three new papers say the measurements were fine but the interpretation was not. Let's take
I Was Offered Money to Tell You AI Will Kill Us
There is money in telling you AI will destroy humanity, and there is money in telling you it will improve your life. Both sides are quietly paying creators to make the case. Some of it is disclosed properly and some of it very much is not. Let's take a look.
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 implicati
Dark Matter Finally Detected?
The dark matter search LUX-ZEPLIN has announced that they have made a detection that could be the first ever evidence for a dark matter particle. Just what have they measured, what could it be, and what does it mean? I have a brief summary.
The Hugging Face Hack Was Much Worse Than I Thought
I looked at the reports about the OpenAI/Huggingface incident and I think we're not talking enough about the most worrisome part
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
Breakthrough: New Type of Matter Discovered
Scientists have discovered a new type of matter. Inside a cooled crystal, structures spontaneously arranged themselves into a three dimensional weave, and they did it at around room temperature. The researchers can even rewrite parts of the pattern with a laser. News like this doesn't come every day. Let's take a look.
Just One More Dimension and Dark Matter Is Solved
String theory has been famously untestable for decades. This week the Economist reported that has changed, and the reason involves an extra dimension of space that might be just big enough to notice in a tabletop experiment. There is a rather different way to read the situation. Let's take a look.
Warp Drives Can Explain Some UAP Observations, Physicist Says
An astrophysicist has claimed that some unidentified anomalous phenomena that were observed in recent years in the United States might be warp drives. He has written a paper about it in which he calculates how such a warp drive would look. I have a brief summary.
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 to
The First New Nuclear Fusion Idea for Decades
A nuclear fusion startup in New Zealand just published a design for a "levitating dipole" reactor, an approach almost everyone had written off as fundamentally flawed. It’s the first new idea in nuclear fusion design for decades. Let's take a look.
