Question

Where did antimatter come from and can there be a large quantity of it?

Answer 1

You can certainly have as much of it as you want.  It takes energy to create it, and when the antimatter comes into contact with regular matter, that energy is release all at once.  To prevent loss, you put it in a vacuum and suspend it with a magnetic field.  This works with charged ions.  However, anti-hydrogen has been made.  That is, anti-protons with positrons in orbit.  No idea how this was contained.  Should be able to have anti-chemistry.

In principal, there could be whole anti-galaxies.  None have been detected.  If there were many of them, we might have witnessed an interaction with a positive galaxy by now.  But short of that, we shouldn't be able to tell.

Answer 2

Matter and antimatter were both created at the same time, and *almost* in the same amount.  There's a theory why it wasn't created in equal amounts, but the upshot is that there was more matter than antimatter, and the two anihilated each other shortly after the Big Bang - leaving the mass of the Universe to be made up of matter.

Antimatter *can* be created - it has been, at least in the sub-atomic level - but around matter, it won't exist for long, because the particles in Antimatter are not only destroyed by the particles of matter, they're *attracted* to each other - making it very hard to isolate particles of antimatter for very long.

Answer 3

When matter self implodes from the tremendous gravitational and atomic forces it creates a vacuum that sucks in space and possibly time itself. Like a suction cup.
