I believe the density will vary, depending on what part of space, for example: (a) The space between the planets within our Solar System, (b) The space between star systems within our Milky Way Galaxy, (c) The space between galaxies, and (d) The space outside of our Local Group (that is, outside of a galaxy group). Also, I don't think the numbers are known precisely. From the Wikipedia article on "Outer Space": "...However, even in the deep vacuum of intergalactic space there are still a few hydrogen atoms per cubic meter." And, in one of the footnotes: "...This source estimates a density of 7 × 10−29 g/cm for the Local Group. An Atomic Mass unit is 1.66 × 10−24 g, for roughly 40 atoms per cubic metre." Note that they are talking about estimates - there is probably no precise information available.
it takes them many years because they have to get us to the life style they will have to be using for outer space. they have to relearn every thing more different because outer space is alot different then the world that we live on.
This is a very generic question, What do you mean by "information" Humans obtain many different forms of information from outer space, information regarding physics? or do you mean information from satelines?
They go to outer space in a spaceship today.

I'm a professional but even i don't know how many astronauts go into space a year too many to count
