Sabine Hossenfelder: Backreaction

In 1983 Benjamin Libet found that brain activity predicts your movements before you are aware of deciding to move.

I looked at the reports about the OpenAI/Huggingface incident and I think we're not talking enough about the most worrisome part

String theory has been famously untestable for decades.

There is money in telling you AI will destroy humanity, and there is money in telling you it will improve your life.

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.

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.

Artificial intelligence has eaten mathematics.

An astrophysicist has claimed that some unidentified anomalous phenomena that were observed in recent years in the United States might be warp drives.

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).

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.

Scientists have discovered a new type of matter.

Could our universe have been born inside a collapsing star?

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.

You've probably heard that quantum mechanics is spooky, that measuring one particle instantly affects another across any distance.

The origin of life is one of the biggest mysteries left in science.

How special is Earth?

The war on artificial intelligence is no longer just online arguments and complaints about data centers.

Neuroscientists have long assumed that when a brain region becomes more active, more blood flows to it.

The dumber you are, the more certain you are that you aren't.

A worker at a US government lab got bitten by a monkey carrying a deadly virus, and it turned out nobody knew what to do about it.

One answer to the Fermi Paradox is that advanced civilizations develop AI and lose interest in space travel.

Over the years, physicists have become increasingly enamored with “quantum weirdness,” the many strange features of quantum mechanics that are extremely hard to explain.

A physicist built a mini-universe out of cold atoms and used it to test where time comes from.

Putin's former thesis advisor is convinced that oil never runs out, and Russia is now drilling 8 kilometres into the ground to prove him right.

Everywhere, it turns out, is warming faster than the rest of the world.
