Thnx guys, great help.

I noticed that in quantum physics, an elementary particle has no dimensions, and is point like, but in string theory has one dimension. Why is this?

I do believe that elementary particles are one-dimensional, not zero-dimensional.

If you mean that Earth is separate from space (like in a small bubble outside space) then no. Earth is indeed in space. "Space" is quite well named, as it's in every space that isn't taken by an object, e.g. a brick. So when you're walking along the road, you're still in space, as to say.

Surely that means that super-massive black holes could work as the cosmological constant, along with dark matter, but also could bring the end to whole solar systems, maybe even galaxies.

After some thinking, it seems that it is not so much decaying so much as metamorphosis. It looks as if, for instance, the muon transforms into an electron and 2 neutrinos. This would also explain your other question, if turned around. Remember Einstein's equation, e=mc2, this implies that mass...

Ah, I think I misunderstood a little. Surely A WOULD be composed of B and C?

Perhaps, but you would be pulled apart by the immense gravitational pull before you got through it, which is why we don't know for sure. Also, I don't think they are "holes" so much as spheres, because, after all, they are collapsed stars.

Doesn't that mean that some valuable metals may have come as a result of meteorite impacts?

Are particles B and C elementary particles?
