Originally posted by lemon limeI think we pretty much ruled out a steady state universe since we see the universe is expanding, which is not an attribute of a steady state. So we are in the process of either expanding (in our little space time realm) forever or at some point in time we reach a max stretch and we start contracting again, the oscillating universe concept. Since we don't know if our universe has done that before the only thing we can say is for right now, the universe is expanding and we noted that about 5 billion odd years ago it appears this expansion sped up for some as yet unknown reason.
A steady state universe means the universe has always existed in its present form.
An Oscillating Universe contracts but stops short of reaching a singularity before it begins expanding again. The Oscillating Universe theory was proposed to overcome a problem with trying to reverse engineer the Big Bang back to its very beginning. The theory resembles ...[text shortened]... y State universe, except that it oscillates instead of remaining in a steady state of existence.
That is pretty much how it goes scientifically for now, news at 11.
Of course the RJ's among us will soundly refute such radical ideas and say Godidit 6000 years ago and everything else is nonsense. That is to be expected.
My personal opinion is we live in one universe among many others and there is some evidence of other universes banging into ours early on, the record is there in deep analysis of the CMB.
There is a theory that what we see as black holes in our universe creates a new daughter universe, perhaps with physics just a tiny bit changed, maybe the speed of light 186,243 miles per second instead of 186,242 miles per second in our universe, stuff like that.
And the implication there is our universe came from a black hole in a parent universe where the laws of physics were a wee bit different from ours, like the speed of light was 186,241 miles second and so forth.
Of course this is all total speculation at this point but it is fun to visualize all this.
