Hi Brain Dwarf, I don't agree with your reasoning (in your statement): 'because the universe is all there is...then it must be infinite'
. Professor Brian Cox touched on the subject of 'Oblers Paradox' during his astronomy program this week. (BBC Stargazing Live, Pt1). He seems to believe (as I do) that the universe is not infinite.
I thought Deuterium's comment about 'red shifted light' was very interesting though.
Happy New Year!
