Thanx:-) I would also like to ask if we are sure that the speed of light has allways been the same, or if it is somehow affected by the expansion of the universe? I will search the treads for an answer, but i apritiate any good explination to this:-)
Can we really say that the universe is accelerating its expansion because we find that galaxies further away have more redshift? We know that we are looking back in time when we look at the stars, and when we look at the galaxies furthest away from us, we are seeing them as they were a long time...
