Stephen Hawking and
Jim Hartle 1983 suggested that the
Universe is
finite but does not have any
boundaries. ("
Wave function of the universe",
Physical Review vol D28, pages 2960-2975) So far, all observations and calculations agree with this. There is no boundary and there is
absolutely nothing outside this nonexisting boundary. A finite number of stars in a finite universe. (I have no idea if this
contributed in a
constructive way the way I had hoped.)
On request, on "no boundaries": "No boundaries" is a
mathematical boundary condition, which seems to be correct compared to what has been observed in
fluctuations in
background microwave radiation. I cannot draw any
physical or
philosophical conclusions of this, myself, unfortunately.
Most important though, and the commonly accepted solution to Olber's paradox is that the universe is so young that only a tiny fraction of all light has reached us yet.
