Crazy New Physics Anomaly: Anti-Matter Helium Detected

Enjoy 10% OFF on all Hoverpens and free shipping to most countries with code SABINE:

A small experiment aboard the International Space Station, the Alpha Magnetic Spectrometer, found a crazy new physics anomaly: They have now detected 10 nuclei of anti-matter helium -- way more than expected. What could explain that? Most of the explanations that physicists have come up so far say it might be a relic of dark matter. Let’s have a look.

2:05 To be fair, when Romeo met Juliet, they annihilated pretty quickly.

[alieninmybeverage]

Aliens: "Radio signals are too easily dismissed, let's try anti-helium!"

PUNY HUMANS: "dark anti simulated holographic multiverse detected?!"

[okman]

Everyone is talking about Anti particle but nobody ask How is Uncle particle 😞

[carlbrenninkmeijer]

Now I think : it does not anti matter

[bradzylman]

Dark matter somehow makes Anti-Helium? That's a pretty funny way to say, "We have no idea".

[GeoffryGifari]

Could it be that the solution to "matter-antimatter asymmetry" is not that antimatters aren't there naturally, but they're just so far away and in isolated clusters due to rapid expansion like inflation (?). Maybe we just happen to be in a matter cluster

My skepticism was annihilated with anti-skepticism and now I am releasing a lot of energy with no opinion.

[AdvantestInc]

The explanation of antimatter in this video was spot on—simplifying such a complex concept without losing its wonder. The way you break down these intricate topics is truly a talent, making high-level physics accessible and engaging for everyone.

[DisFuntastic]

Would you also get a funny voice when inhaling anti-matter Helium?

[bencrossley]

Sabine,

Many years ago I said to a lecturer at uni that anti-hydrogen should be element -1, anti-helium element -2 and so on. He agreed that this was sensible.

Please perputuate my one and only good idea XD

[nosuchthing]

Little known fact: inhaling anti helium gives you a super squeaky voice. For a femto second.

[Techmagus]

The plasma balls are a very new papers that addresses that not only the amount of anti-helium is unexpected, but the ratio of anti-helium(3) to anti-helium(4) is unexpected too. But we have to be very careful as the numbers of particles detected by AMS is very high, but the anti-helium is extremely low(even if far higher then expected) and with low examples comes high uncertainty.

[laurentbasara]

0:18 it made me sad to learn AMS-02 was not an actual particle detector :( having done my PhD and post-doc on it, I had always believed it was.

This reminds me of a hypothesis I remember hearing about where even if we did find alien life, there's a chance that we could never come in contact because they'd be made of anti-matter.
The reasoning being that outside of a few niche situations _(like the rotation of a particular particle being asymmetric between the two - I forget which one), _ it's impossible to tell matter and antimatter apart without measuring its polarity; combined with the theory that it's entirely possible that we only *_think_* the universe is made up of entirely matter solely because our little section is made up of matter, and that space is so big that it's entirely possible that some of the stars you see in the night sky are actually "antistars." Even if we communicated with distant aliens and asked, simply measuring the polarity wouldn't actually solve anything because to them, *they'd* be the ones made out of matter. The concept of "positive" vs. "negative" is entirely arbitrary, especially when the way to measure it is via other "positives" and "negatives" like from magnets.
The fact we're able to pick up antihelium - what would be the primary exhaust of antistars - at such an amount helps solidify the hypothesis for me.

[AllanDoane]

Question: what holds the anti helium nucleus together? Is it the same strong force of regular matter?

[DN]

Dark matter as the explanation for everything that you can't explain is so convenient since no-one can disprove it for the lack of dark matter in the universe.

[Jefuslives]

Science: There's too little antimatter. It doesn't make sense!
Also science: There's too much antimatter. It doesn't make sense!

[andrearaimondi]

The quantity of anti helium is absolutely staggering. Holy moly!

[David-lcw]

It's not often I have to correct Sabine, but anti-particles not only have an opposite charge, but they also each have a goatee.

[VFFP]

That's nothing new. Death metal vocalists were inhaling Anti-Helium since mid 80's.
