does antimatter have dimensions?

Question

If yes, how do you measure it?

Answer 1

Yes.

Anti-matter is matter - just the opposite of what we are used to.

We measure it in the same way.

Although we can encounter anti-particles regularly, we don't normally encounter anti-matter - atoms or molecules based on positrons and negatrons. However, apparently some labs have been able to generate small amounts of "anti-hydrogen".

Answer 2

Because anti-matter is just the antiparticle of the corresponding normal particle yes in general it does. An anti-proton has the same "size" as a proton. A positron is a point particle like an electron(thus no dimension). An anti quark is just the anti version of the normal quark. I saw "size" because these are quantum mechanical things and dont have dimension like we are used to.
Also just so you know, there is no known anti matter of large quantity.. so no antimatter objects are out there as far as we know. Also the dimension might be slightly different than the normal particle, it hasnt been measured directly but most scientists doubt it because they expect a symmetry here.

Answer 3

Yes but it couldnot be measured .May be there must be a way to calculate it.
In the Case of positron which is an electron particule skin made up of dark matter it would be in the order of 1.35 x10^-15 meters.

Answer 4

anti-matter is created when two atoms collide at light speed if it's called anti-matter idt it has dimension
