What is space, really? That’s one of the biggest questions in science. According to a pair of researchers from the Perimeter Institute, the answer to that is: a quasicrystal. What is a quasicrystal, and how is space a quasicrystal? Let’s take a look. www.youtube.com/watch?v=0azO...

In a recent paper, scientists at Microsoft revealed that they’ve found a way to store data for more than 10000 years by laser-etching pieces of glass. There are also a few other interesting ways that researchers are improving other storage technologies. www.youtube.com/watch?v=aCma...

Do we live in a computer simulation? So far this question has been pursued mostly by philosophers because it was just too vague to make scientific sense of it. But this situation has changed now. www.youtube.com/watch?v=UbIn...

The Milky Way might not have a black hole after all. www.youtube.com/watch?v=roNZ...

The first ever human spacecraft to land on the moon wasn’t Apollo 11 – it was the Soviet Luna 9 probe, which touched down three years before the Apollo lander. For decades, researchers have for some reason been unable to track down its location … up until now. www.youtube.com/watch?v=rrRa...

If the headlines are to be believed, kids these days are getting dumber. Some of the data – which indicate that Gen Z individuals are performing worse than their parents in standardized testing – backs this claim up, but this isn’t the full story. www.youtube.com/watch?v=n9lm...

"it’s not so much that theory..disappears, but that we can leave it to AI to develop. It’s theorists that disappear, not theory" "I’ve already talked a few times about how AI is taking over maths. This is no longer hypothetical, it’s happening. And theoretical physics is next, we can see it coming"

Finally a clue to the Havana Syndrome mystery www.youtube.com/watch?v=Rd1e...

Fusion reactors, according to a recently published paper, could produce theoretical particles that might make up dark matter. I've had a look at the paper. www.youtube.com/watch?v=eRKx...

I used to think that quantum computing's threat for bitcoin is a far-fetched worry (and not my problem anyway) but I have recently changed my mind. www.youtube.com/watch?v=rjYF...

Nuclear fusion breaks multiple records. What does it mean? www.youtube.com/watch?v=IuMW...

A group of physicists say they found a solution to the problem of singularities in Einstein's theory. www.youtube.com/watch?v=b86Y...

One of my favorite videos of hers this year. Being a natural geometric savant (yes I was an autistic study kid of the 80s) I find their work fascinating though Exceptional Lia algebra frameworks though so few take this route. Even less also do work rectifying it with Teleparallel gravity work.

I'm in the "Epstein files." @hossenfelder.bsky.social I got some questions about the appearance of my name in Jeffrey Epstein's inbox. Turns out to be about... quantum gravity, unbelievable as that sounds. Here is the story and why I am still pissed off about this. youtu.be/ZxxNENOBD6w

Is the scare about plastic nano- and micro particles’ impact on human health justified? @hossenfelder.bsky.social takes a look and finds that the evidence for significant detrimental effects is weak or dubious, or non-existent: youtu.be/pyGvCtkIuDk

Today I talk about how more quantum computing use cases are disappearing, and an unexpected problem with quantum computing in general. www.youtube.com/watch?v=N-9m...

According to a new paper published by a group of astrophysicists, simulations seem to indicate that our galaxy cluster exists in a thin area of highly concentrated dark matter, which itself is located between two voids of dark matter. www.youtube.com/watch?v=BHAO...

Humanity is on its way to prevent space travel for a long time. Good for the aliens, I would say. Side note: GPS and internet access might be affected or even destroyed, in the long term, too...

Over the past few months, we’ve seen a growing number of headlines claiming that AI has solved math theorems that have remained unsolved for decades. Is this true? And if so, does this mean mathematicians will soon find themselves out of a job? Let’s take a look. www.youtube.com/watch?v=IKjf...

We are much closer to the Kessler syndrome than we thought. www.youtube.com/watch?v=8ag6...

Why does light exist? It's a consequence of what physicists call a "gauge symmetry" and in today's video I do my best to try and explain how that works. www.youtube.com/watch?v=0Rca...

According to new analysis, the reality of biofuels doesn’t match the models, and synthesizing and burning the fuels might actually increase the amount of carbon dioxide in the atmosphere. www.youtube.com/watch?v=6Nu-...

In a recent paper, physicists have come up with a quantum physics paradox that seems to show that we can change the past with quantum physics. www.youtube.com/watch?v=Xb9G...

Why does space have 3 dimensions? Why not 2? Or 4? Or 7? It’s because physics wouldn’t work properly. Let’s take a look at the major reasons for why physics needs 3 dimensions. www.youtube.com/watch?v=DqI2...

Physicists revisit the idea that dark matter is just normal matter www.youtube.com/watch?v=ffLD...

According to a new paper, we’ve misunderstood how gravity works. The authors say that gravity really can do action at a distance and that explains the observations that we currently ascribe to dark matter. www.youtube.com/watch?v=1WgN...

It's amazing how many new ideas scientists have come up with to spy on others www.youtube.com/watch?v=UYWj...

The #1 most-wanted particle in physics is the graviton, a quantum of gravity. In a recent paper, a physicist came up with an ingenious experiment that could prove that gravitons do exist. Let’s take a look. www.youtube.com/watch?v=qXwp...

It’s a new year, and according to a new paper, physics is headed into a new era. Over the past few years, the field of physics has seen a major shift in research priorities – let’s take a look at that shift, why it’s happened, and where physics is headed next. www.youtube.com/watch?v=iJWF...

Human brains are roughly 100,000 times more energy-efficient than current AI systems. So why don’t we build computers using human brain cells? Don’t worry, researchers are one step ahead of you there. www.youtube.com/watch?v=gC_r...

I have been alerted that black holes don’t exist, again. This isn’t the first time I have been asked to assess an argument which seems to prove that black holes aren’t real, but let’s take a look at all the new developments in this debate. www.youtube.com/watch?v=3HJG...

Physicists have theorized for decades that chaos doesn’t just destroy order, it can also create it. This could in turn mean that the laws of nature that make our universe the way it is could be emergent from chaos. www.youtube.com/watch?v=xDOV...

In today's video, I have a look at the return of DC electricity. www.youtube.com/watch?v=jFA4...

Wormholes are hypothetical tunnels in spacetime that appear in both Einstein’s theories and quantum physics. Recently, wormholes have been making a lot of headlines. Why is that? www.youtube.com/watch?v=PwXa...
