What Does Anti Matter Look Like

In modern physics antimatter is defined as matter which is composed of the antiparticles or partners of the corresponding particles of ordinary matter.

What does anti matter look like.

Antimatter should have annihilated all of the matter in the universe after the big bang. It turns out as far as we can tell it looks like an exact mirror image of regular matter. Experimentally there is no difference between the spectral lines of antihydrogen and of ordinary hydrogen. Anti matter will combine with normal.

According to theory the big bang should have created matter and antimatter in equal amounts. When matter and antimatter meet they annihilate leaving nothing but energy behind. Antimatter looks exactly like oridnary matter as long as it does not enterin touch with matter as then it explodes in a spectacular annihilation. Theoretically anti matter should look just like normal matter.

Scientists learned something crazy about antimatter this morning. Cern experiment makes spectroscopic measurement of antihydrogen. A proton has a positive charge while an antiproton a negative. The basic difference between matter and antimatter is that they have opposite charges.

So in principle none of us should exist. Anti water for example would still be h2o and would have the same properties of water when reacting with other antimatter. What would an antimatter universe look like. But okay what does that even mean.

However we ve never been able to make enough of it to see which is probably just as well. Real antimatter looks just like regular matter. Then i show you what happens i. Minuscule numbers of antiparticles are generated daily at particle accelerators total production has been only a few nanograms and in natural processes like cosmic ray collisions and some types of radioactive decay but only a.
