and WHAT'S the point? And don't start a science argument.
anti matter is anti matter
I have to agree with Kydon.
Antimatter is just what is sounds like, Anti-matter. It is a different state of matter, in fact it is not matter at all. Therefore it cannot pass through the walls of the regular states of matter. The moderators made no errors when coding it, this is it's true nature. Simple. +1 for asking a question that I could answer.
also, not really FP worthy.
I dont really know why this is on FP. Antimatter isn't the opposite of matter, per se. Antimatter doesn't contain any of the properties we observe in our states of matter, i.e. Solid, Liquid, Gas, Plasma, Superfluid, Supersolid, or Bosons. When the Universe began, there was an equal amount of 'antimatter' created as normal matter. All they do is cancel eachother out. Thye show no other properties that we know of because we have never observed enough antimatter to see any properties.
antimatter = it isn't a matter = it isn't liquid, powder etc.
Dude, antimatter particles are really just tiny portals into the Dirac Sea. TPT doesn't know what to do with tiny mobile portals.
