and Jim Hartle 1983
suggested that the Universe
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
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.
