There are some properties of the Universe I find in the (mostly popular) literature which are often described as "the most probable in case of our Universe". I can't put them together in a way that doesn't confuse me. Here they are:
- the Universe curvature is flat
- the space is infinite
- the amount of matter is finite
- the matter distribution is uniform
The first three assumptions seems to contradict the last, because from what I understand, if you run in one direction long (and fast) enough through a flat, infinite space with a finite amount of matter, you will eventually run out of galaxies and go into an empty space. Is that true, or I just don't understand some of the above concepts?
