What does antimatter look like?

Question

Just curious as to take antimatter looks like by itself and then when it contacts matter? I haven't seen any real answers to this.

Answer 1

We dont know. Let me put this simple If I try to put antimatter in a bowl, it will explode. Because the bowl is made of regular matter it will burst into pure energy.

Answer 2

Antimatter really pretty much "looks" and acts like matter when it's no where near matter.  For instance, a positron is an anti-electron.  It behaves just like a positive electron would.  It's got the same mass, it's got the same spin... it's essentially exactly the same except for the charge.

*But* what happens if a positron and an electron get close enough to each other to interact?!  They *annihilate* each other - they make each other *cease to exist*!  In the case of positrons and electrons, when they annihilate, they create two photons (because they both had mass, they both had energy.  You know, good old E=mc^2, meaning you can "convert" mass to energy and energy to mass)

Anyway, anti-matter isn't all that weird.  In fact, the weird thing is that there isn't more anti-matter around.  Be thankful though, or if a galaxy of antimatter objects came ripping through our galaxy, we might be in trouble (that whole annihilation thing doesn't sound good to me).  But fortunately, astrophysicists are pretty keenly looking around for anti-matter, so we're pretty safe.
