Breakthrough In Data Storage Could Store Your Photos for 10000 Years
Breakthrough In Data Storage Could Store Your Photos for 10000 Years YouTube video by Sabine Hossenfelder

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.

The Simulation Hypothesis Gets Scientific Backing
The Simulation Hypothesis Gets Scientific Backing YouTube video by Sabine Hossenfelder

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.

The First Moon Landing Wasn’t Apollo β€” And We Just Found It YouTube video by Sabine Hossenfelder

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.

Gen Z Isn't Dumberβ€”Here's What's Actually Happening YouTube video by Sabine Hossenfelder

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.

"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"

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.

@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.

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:

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.

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...

The AI Maths Revolution Has Begun
The AI Maths Revolution Has Begun YouTube video by Sabine Hossenfelder

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.
