Answer 5

Yep...the most well know pairs are electrons and positrons.  The charges plus and minus are the only difference between the two.  Otherwise, they are identical.  And this is true of all the other particles: muons, leptons, photons, etc.  They have anti equivalents with different charges as well.

Anti particles have very very short lives.  Which is why we don't normally see anti particles in daily life or the labs.  They are continually popping into and out of existance.

And speaking of labs, whenever they make matter out of energy, invoking E = mc^2, they invariably create anti matter.  That is, they cannot make matter without also making antimatter.  There is a sort-of symmetry in our universe...a ying and a yang.
