Hello, I heard a scientist on the radio claiming that, if the universe is infinite, that all possible combinations of matter/energy exist somewhere in that infinite-ness. So, for example, as I sit typing, I am wearing a gray sweater. As I understand it, somewhere in the infinite universe I exist doing the same typing but wearing a red sweater. But, what I don't understand is, this scientist said there was a finite amount of possible combinations for matter/energy. Is that really true? As I understand it, the possible combinations of distance between, say, two atoms would also be infinite. So, if both space and matter/energy-combinations are infinite, doesn't that mean that the existence of every possible combination of matter/energy is an impossibility?
