easy. There's no matter in the area. say, you have one cubic feet of space. Instead of acubic foot of air, where there is hundreds and thousands of molecules and atoms, there are very few atoms, and they are very spread a part. the space that exists between the particles is a vacuum, which is the absense of particles.<br /><br />Also, stop posting new threads. just keep replying in one, please.
vacuum. But there is far... (for lack of a better term) More atoms than vacuum.this vacuum also exists between the nucleus and it's electrons and between the neutrons and protons. all these little subatomic particles exist in the void, but they do not make up the vacuum.
i suppose you could say every object smaller tahn the universe is "subuniversal" but that's usually not a fact that's important to anyone, since everything we can see is clearly smaller than the universe it's in.
