Can anti matter be seen?

Particles of matter and antimatter are identical, except for an opposite electrical charge. An electron has a negative charge whereas its antiparticle, the positron, has a positive charge, and both have an identical mass.

How is anti matter different from matter what happens when matter and anti matter come in contact with each other?

Matter and antimatter particles are always produced as a pair and, if they come in contact, annihilate one another, leaving behind pure energy. During the first fractions of a second of the Big Bang, the hot and dense universe was buzzing with particle-antiparticle pairs popping in and out of existence.

Where is the anti matter?

The antimatter is missing – not from CERN, but from the Universe! At least that is what we can deduce so far from careful examination of the evidence. For each basic particle of matter, there exists an antiparticle with the same mass, but the opposite electric charge.

Why do we think there was slightly more matter than antimatter in the early universe What happened to all the antimatter and when?

Why do we think there was slightly more matter than antimatter in the early universe? What happened to all the antimatter, and when? Because the universe contains a significant amount of matter now. The antimatter was all annihilated leaving ordinary matter that is in the present-day universe, during the Particle Era.

Can protons travel backwards in time?

Yes. According to the CPT theorem, antimatter is matter going backwards in time, but when viewed through a mirror.

Does anti-matter act like matter traveling backward in time?

“Anti-matter acts like matter traveling backward in time”. Technically true, but not in a way that’s useful or particularly enlightening for almost anyone to know. This isn’t as useful an insight as it might seem.

How do anti-matter particles interact with each other?

All anti-matter particles have the opposite charge of their matter counterparts and their parity is flipped in the sense that when anti-particles interact using the weak force, they do so like matter’s image in a mirror. When an anti-neutron decays into an anti-proton, a positron, and an electron-neutrino, the positron pops out of its “north pole”.

How does an anti-particle behave in the past?

In physics, whenever you’re trying to figure out how an anti-particle will behave in a situation you can always reverse time and consider how a normal particle traveling into the past would act. “Anti-matter acts like matter traveling backward in time”.

Is it possible for a particle to move backwards in time?

What they came up with was a particle that matched the known properties of the positron. Just to give you a rough idea of what it means for a particle to “move backwards in time” in the technical sense: in quantum field theory, particles carry with them amounts of various conserved quantities as they move.
