How much energy AI really needs. And why that's not its main problem. | 8:05Sabine Hossenfelder | 1.19M subscribers | 171,326 views | March 25, 2024

My new essay is here: https://nautil.us/what-physicists-hav...We've seen a lot of headlines in the past year about how dangerous AI is and how overblown these fears are . I've found it hard to make sense of this discussion. If only someone could systematically interview experts and figure out what they're worried about. Well, a group of researchers from the UK has done exactly that and just published their results. What they have found is, not very reassuring. Let's have a look.The paper is here: https://ieeexplore.ieee.org/document/...AI experts make predictions for 2040. I was a little surprised. | 6:57Sabine Hossenfelder | 1.13M subscribers...

I got a lot of questions last week about an article in Quanta Magazine about Dark Dimensions. it's about an idea motivated by string theory that combines large extra dimensions with dark matter. I had a look at the paper.The paper is here: https://arxiv.org/abs/2311.05318The article in quanta magazine is here: https://www.quantamagazine.org/...String theory nonsense makes comeback | 8:12Sabine Hossenfelder | 1.13M subscribers | 147,734 views | February 7, 2024

In this week's science news, I talk about a new candidate for a cosmic string, the mysterious shrinking of planet Mercury, a nuclear clock, the first quantum engine, a simulator for human diseases, whether we can find new physics with spinning black holes, AI that wants to help find aliens, how to compute with photons, and of course, the telephone will ring.Could this be the first evidence for string theory? | 18:21Sabine Hossenfelder | 1.03M subscribers | 310,893 views | October 10, 2023

A very brief video because I want to tell you about this story I learned from William Jason Morgan's obituary. It's a lovely story about how the process of scientific discovery sometimes takes unexpected turns.He looked for gravitational waves, but discovered something entirely different | 3:39Sabine Hossenfelder | 1.03M subscribers | 232,486 views | October 19, 2023her YouTube channel

If you've been following my channel for a really long time, you might remember that some years ago I made a video about whether faster-than-light travel is possible. I was trying to explain why the arguments saying it's impossible are inconclusive and we shouldn't throw out the possibility too quickly, but I'm afraid I didn't make my case very well. This video is a second attempt. Hopefully this time it'll come across more clearly!I Think Faster Than Light Travel is Possible.
