great explanation and animation!
Interesting! Is this the first time we definitely learned that antimatter behaves just as normal matter in relation to gravity?
Sounds like it.
Yes!
@@arsonor groundbreaking stuff, amazing! 😊
These experimental data actually tell us that it's very unlikely that matter gravitationally interacts with antimatter through something like antigravity (a repulsive gravity). But it's still possible that there is a tiny difference (not involving antigravity) in the way they interact. They are working on experiments having lower and lower uncertainty of measurement in order to figure it out.
Antiprotons were first produced at CERN for the Proton-Antiproton Collider experiment which ran from 1981 to 1991 as a six-month-per-year experiment on the Super Proton Synchrotron.
AWESOME!!!!! love this - and its useful step forward.
WOW, interesting.
Awesome music I wish that scientists would be quiet so we could all properly appreciate it
The scientists also made the music...
Really brilliant! Awesome! That is a great news! Until now, nobody knew! Now we know for sure!
This is so cool. Can we call it and make liquid anti hydrogen? Also is it potentially possible to make anti water one day? Or what would that be called.
I was hoping it goes up.😅
You aren’t alone. Electromagnetic forces can be attractive or repulsive, depending on charge interactions. Like charges repel, opposite charges attract. Gravity to date is attractive only, but I was leaning towards a model of “like matter attracts” and “antimatter and matter repel”. That doesn’t seem to be supported by this experiment.
@@arsonor Anti-matter has positive mass, just like regular matter, so there's not really any reason to expect anti-matter to be repelled by a gravitational field from a regular matter particle. It's their charges that are flipped.
@@tacocookie1015 perhaps I was just wishing it was true.
@@tacocookie1015 wait.. but they are anti particles. Isn t their mass like anti mass or a "negative" mass?
No. Anti-matter is only "anti" in the sense that the charge and other quantum numbers like lepton number change signs. The mass is exactly the same between a particle and the respective anti-particle.@@herrdani
Anti matter is matter that we have no instruments to monitor that low in energy value terms as its phase waves are so small but interact over time and temp
What if Earth gravity is too strong to observe the effect?
I'm 50% thinking that the result of this experiment is right, but the other half is thinking that we don't know enough to stop at this point. If antimatter annihilates with regular matter producing so much energy, there must be a difference between the two.
I don't know if it's more crazy to take a sample where there's no gravity, or to produce and test a bigger quantity here.
Anyway don't give up please, this is a great achievement already!
hey can i buy a jar full of those positrons? i need them for something ...
1:05 A magnetic bottle that holds onto neutral atoms? How does that work?
Brilliant video , I have a question : What are the properties of antihydrogen ? , is it the same as normal Hydrogen ?
yes same
How come it is neutral when normal hydrogen isn't?
@@antoniobrown6210normal hydrogen is neutral as well
@@antoniobrown6210normal hydrogen is neutral, for the same reason. The opposite charges of the nucleus and electron (or positron) cloud cancel out overall. Both normal and antihydrogen are somewhat diamagnetic, especially in the para state, and that is what they are using to hold the antihydrogen in place
LOVE U.
Something tells me you guys have already found the missing link to the Hydrogen and Renewable Energy problem....But the take : "It is not yet our Problem"
I think it is more interesting to move towards natural objects. For example, in the direction of ordinary, but metallic hydrogen and understand whether there are several states of metallic hydrogen, as a reflection of the structure of aggregate states, conditionally, “from above”. That is, whether there is a state of metallic hydrogen of stage one and stages beyond. Such as the stages of rotation in a proton, for example, at least one more, looking like the limit of rotations to the state of four stages of everything, similar to the icon of a BMW car, or similar to the icon for the sun in ancient texts, a cross in a circle, and not so many feet , as the primary state of the quantities of steps of the first encountered metallic hydrogen. Then there will be a symmetrical number of states of aggregation, according to the limit from the edges.
And this relates to ALPHA-G how exactly?
@@polarisukyc1204 😂
Great, now figure out how to store it at scale and use it for space craft propulsion!
To see the effect, you need antihydrogen the mass of Earth. Or fly away from the Earth so that the force of anti-gravity is comparable to the force of gravity.
would it be possible to create fusion with antihydrogen? Could antihelium and other antielements also exist?
As far as we know, antimatter is simply regular matter but with opposite charges. For example, the anti-proton is negative while the anti-electron (the positron) is positive. You could do fusion with them, but it would be identical to regular matter fusion in terms of energy output. And yes, we could hypothetically make other anti-elements.
There’s an idea. I wonder what dynamics would exist in a plasma of hydrogen and anti-hydrogen. It wouldn’t annihilate instantly as despite the energy of the particles, they would still need to impact each other. I wonder how long such a plasma would last
you dont need fusion to produce energy you can simply mix with normal hydrogen and it will annihilate and produce energy
@@polarisukyc1204 It will immediately annihilate
@@BondJFK not necessarily, a regular plasma is made of negatively charged electrons and positively charged ions, but it doesn’t instantly recombine into a neutral gas does it, there is also the matter of reaction cross section and temperature of the particles and antiparticles to consider
