Okay, well I guess I couldn't resist.Its so simple: The universe is physically and timewise infinite. This leaves no unanswered questions. Any other hypothesis require all kinds of wild assumptions to be made in support of of it; especially when people start asking hard questions; then the wacko meter starts going off the chart, or you get science's shotgun answer "well we just don't know that yet"
I actually find this a bit offensive.
Let me see if I can come up with a few unanswered questions for you, given an infinite universe that has been around forever.
If the universe is infinite and has been around forever, then:
1) Why are there stars still burning? Forever is a long time, why has all the hydrogen not long since been used up?
2) Given that in about 15 billion years, this galaxy will be just a bunch of cold rocks. Also given an infinite life to the universe, there should be an infinite number of cold galaxies around. Is there some interesting explanation as to why we have not seen them?
3) Given the matter density of local space, if there have been stars burning bight forever, why is it so cold out there?
4) If there has been an infinite number of stars burning for an infinite length of time, surely there would have been enough time for the light of an infinite number of stars to reach this point in space. Then why is the night sky so dark?
5) How do you explain the redshift?
6) How do explain quasars and why they are all so distant and red-shifted?
7) How does spacial curvature fit into an infinite space model?
8) Why is it that distant galaxies all seem to be much younger than local galaxies? I know it takes the light a long time to get here, but forever is a long time. We should see the light from older galaxies, 20, 30, 40, 50 billion light years distant. How come we don't?
Well, I could go on and on and on and on....and these are the easy ones
Please give me good scientifically based answers. I don't need you to quote references or provide equations (you can if you wish though), but also "That's just some yet unexplained property of the universe" won't cut it.
