Does Antimatter Create Anti-Gravity?

I would love to see an episode on how Anti-matter is actually made. What's the process, what are the materials, what reactions have to happen, and why it actually works.

It would be funny if this was a 2 second episode with Matt just saying:"Nope"

I like how Matt keeps bringing up hoverboards like it would be totally safe to have something that if it got into a crash would explode with the force of a Tsar Bomb

Whether or not it disrupted the status quo, this experiment is such an amazing achievement. To think that one of the most exotic forms of matter is merrily floating around in a magnetic field, in CERN, on Earth, created by humans, its simply amazing.

I deeply appreciate how in the split screen rocket illustration, you had the rocket's background Starfield accelerating at increasing velocity instead of just passing by at a constant velocity, reflecting the fact that the rocket is constantly accelerating. Great attention to detail!

Thank you for including the confidence level of the result. That makes or breaks this kind of science communication IMHO

I was in Cern im 2019 and an old physicist who gave us a tour was really excited and told us young students evrything about that experiment. We were fascinated by the implications and that such a raw hypothesis was tested for. Wether or not it was ever plausible to show antigravity it is still excellent science to test for it.

Dear whoever edits/does music for these, PLEASE make the outro quieter! I love listening to these before bed and the last 15 seconds are so much louder than the entire episode. THANK YOU! Sincerely, An overworked mom who just wants to peacefully learn and fall asleep to science

At 3:56 you remove both masses. Acceleration should be a = MG/r^2, with M being the fixed mass of the object you are being attracted towards.

One big issue to me with negative gravitational mass for antimatter is that it implies that particles like photons, which are their own antiparticles, must not interact with gravity, even though we've observed that they do. Is this not the absolute deal-breaker I think it is, or do people just like brushing that to the side when talking about this idea?

A few years ago I had the pleasure of visiting the Antimatter Factory at CERN where they described this experiment to us. It was really fascinating and I'm happy to hear about the results now. One interesting fact I found interesting was, that the were shooting the first antiparticles they generated just straight into a concrete wall just casually standing around in the facility. 😀Nothing spectacular happens, sure, it annihilates with the matter of the concrete and creates 'lots' of energy, but, after all, it's just a single particle.

Love your new look! Thank you again for including the full equations. I love seeing them. I don’t understand and it is motivating to me to learn.

When Spacetime drops, it's always a good day

I just want to say that this channel is one of the biggest helps and inspirations for my studies. You are an excellent, top tier teacher who makes math and physics fun, engaging, and rather easy to comprehend. I've only been watching this channel since 2020, but thank you. I am attending college this fall to start my journey into theoretical physics at the age of 34. It's never to late to learn.

Your reporting of the error bar is wrong. The paper says " a=(0.75 ± 0.13 (statistical + systematic) ± 0.16 (simulation))g." Not sure why you put the  ± 0.13 in the video but not the ± 0.16. If you wanted to keep things simple and only have one error bar, you should have added the two in quadrature, getting ± 0.21. This mistake drastically overestimates the statistical significance of the difference. It's not that it's less than 3 sigma, it's barely more than 1 sigma, and it can even be below 1 sigma if you think those different kinds of errors should be added linearly.

Congratulations on 3M subs! I like the new logo and the new intro. Btw a youtuber called acollierastro made a video about this topic.

Feel better soon, Matt, and take the time you need to fully recover!

Just wrote my bachelor's research project on the matter-antimatter asymmetry of the universe! very cool to watch this video :)

It's incredible how much I learn from this channel.

Anti-matter may not have negative gravity, but Negative Matter should. I'd love to see an episode about the possibility of turning negative energy into negative matter. Also, what's up with dark matter & dark energy? Is there a corresponding anti-dark matter and negative dark energy?
