In 1983 Benjamin Libet found that brain activity predicts your movements before you are aware of deciding to move. Three new papers say the measurements were fine but the interpretation was not. www.youtube.com/watch?v=15s0...

As simple as possible, but not any simpler! Science and technology updates and summaries. No hype, no spin, no tip-toeing around inconvenient truths. Current...
I looked at the reports about the OpenAI/Huggingface incident and I think we're not talking enough about the most worrisome part www.youtube.com/watch?v=19KS...
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. www.youtube.com/watch?v=8_DF...
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. www.youtube.com/watch?v=lPdm...
A group of physicists has shown that the butterfly effect is much stranger than we thought. www.youtube.com/watch?v=8RHL...
An experimental collaboration has reported what may be the first detection of a dark matter particle. I have a brief summary: www.youtube.com/watch?v=9TLM...
Artificial intelligence has eaten mathematics. Physics is next, and almost nobody is talking about it. www.youtube.com/watch?v=utu5...
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. www.youtube.com/watch?v=5ZB1...
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 with small, noisy devices (NISQs). Google, IBM, IonQ, they all gave dates. None of them delivered. www.youtube.com/watch?v=DX_o...
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. www.youtube.com/watch?v=PzDe...
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. www.youtube.com/watch?v=NzQQ...
Could our universe have been born inside a collapsing star? The paper behind the idea describes a new solution to Einstein's equations in which a collapsing star expands on the inside and never forms a black hole. www.youtube.com/watch?v=_vJD...
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. www.youtube.com/watch?v=4WUr...
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. www.youtube.com/watch?v=8e_J...
The origin of life is one of the biggest mysteries left in science. Now a group of researchers says there wasn't just one origin, there were two. www.youtube.com/watch?v=6edA...
Why does our planet have continents? A group of geologists now says the answer lies somewhere unexpected, in the shape of the Milky Way itself. Let's take a look. www.youtube.com/watch?v=4k7n...
The war on artificial intelligence is no longer just online arguments and complaints about data centers. Something has shifted, and law enforcement has noticed. www.youtube.com/watch?v=BvlG...
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. www.youtube.com/watch?v=jHGx...
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. Around the same time, someone from the same lab tried to smuggle outbreak samples into the country. www.youtube.com/watch?v=3KO9...
One popular answer to the Fermi Paradox is that advanced civilizations develop AI and simply lose interest in space travel. A researcher now argues that's backwards: AI, robots, and cheap probes make space exploration easier. Which means the paradox gets worse. www.youtube.com/watch?v=s-Mg...
Over the years, physicists have become increasingly enamored with “quantum weirdness,” the many strange features of quantum mechanics that are extremely hard to explain. In a new paper, a group of researchers have tried to cut through the weirdness. www.youtube.com/watch?v=SMXq...
A physicist built a mini-universe out of cold atoms and used it to test where time comes from. It made big headlines a few weeks ago, and I almost skipped it, as most "universe in a lab" stories are nonsense. But then I actually read the paper. Let's take a look. www.youtube.com/watch?v=Bce-...
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. Is there really infinite oil down there, or is Russia about to end up with a very expensive hole? Let's take a look. www.youtube.com/watch?v=oBUK...
Everywhere, it turns out, is warming faster than the rest of the world. Every region, every country, all of them, faster than the rest. You may sense a slight problem with this. The headlines are real, the papers are real, and yet something doesn't add up. www.youtube.com/watch?v=j9cD...
In today's video I talk about some commonly misunderstood points in the double slit experiment. www.youtube.com/watch?v=npc6...

A group of physicists accidentally found a way to create antigravity www.youtube.com/watch?v=XKRM...

In a new paper, mathematicians claim that dark energy isn’t needed to explain the accelerating expansion of the universe, and physicists have been barking up the wrong tree for decades. www.youtube.com/watch?v=u61N...
The electric car revolution is not going well www.youtube.com/watch?v=_6r9...
Physicists have built a laser based on black hole physics www.youtube.com/watch?v=ixgG...
One of the biggest limitations of quantum quantum computing is the “no cloning” theorem, which says you cannot copy a quantum state without destroying the original. In a recent paper, physicists have demonstrated that there’s a way around the “no cloning” limitations. www.youtube.com/watch?v=gR99...
A new, computer-based calculation shows that our solar system used to have 5 or 6, rather than 4 gas giants. It seems that, billions of years ago, we lost two planets due to an instability that probably also tilted Uranus’s axis and scrambled up its moons. www.youtube.com/watch?v=XcHR...
Recently, a pair of researchers made a massive breakthrough in the foundations of physics. In their paper, they describe how gravity is an emergent property. More specifically, they say that the origin of gravity is entropy. www.youtube.com/watch?v=IxmT...
People all over the world have reported a mysterious "Hum" for decades. In a new paper, scientists have finally come up with an explanation. Or have they? www.youtube.com/watch?v=b52D...
Physicists have been arguing about dark matter for almost a century, and now, after all this time, their most favourite evidence for dark matter – the Bullet Cluster – disappeared. www.youtube.com/watch?v=cqLy...
Over the years, the use cases for quantum computing have been slowly eroded, but investment in quantum tech has only increased. Why? www.youtube.com/watch?v=spRN...
Since the early days of quantum physics, some scientists have believed that there’s a link between quantum mechanics and consciousness. Some recent experiments seem to back up one of those theories, and no, it's not Penrose's www.youtube.com/watch?v=q2T6...
In today's video I speculate about the future of artificial intelligence. www.youtube.com/watch?v=zWQe...

I today's video I look at the recent AI breakthrough in maths and mathematicians reactions to it www.youtube.com/watch?v=k5dZ...

In the past years, physicists have been rethinking the dark matter idea… but not in the way you might expect. www.youtube.com/watch?v=Wdf5...

In general relativity, the time an object experiences depends on its acceleration. But time in quantum physics is a universal parameter. In a new paper, physicists say they want to use a special type of clock to test that difference. Let’s take a look. www.youtube.com/watch?v=j5rw...
Several companies are working on safe nuclear reactors. I've had a look at what's behind it. www.youtube.com/watch?v=d96W...
