okay, I guess I'll just have to do it myself. I'm pretty sure I have seen an estimate of the size of the universe, so I can find that (unless you have that handy). All I need is the PRESENT acceleration of the universe. I am truly amazed at this discussion! It would be like someone asking...
Ok, I didn't think I would have to explain this to get an answer. Let's pretend the Universe is a balloon. Let's pretend that long ago, the balloon was deflated. Let's pretend that this universal balloon began filling with air (dark matter, or whatever you want to fill it with). If the air...
Wow! Talk about inability to think outside the box! (referring to refusal to do the simple calculation regarding expansion of the universe) I don't care what the theory is, I just want to know, out of simple scientific curiosity, how far back in time you would have to go for the expansion rate...
No assumptions made. In fact, you seem to assume that such a back extrapolation would extend before the "Big Bang". I believe the extrapolation would be dramatically fewer years ago than when the "Big Bang" is theorized to have occurred. I think most astrophysicists are afraid to do this...
I have been wondering for a few years if the current equations for the expansion of the universe have ever been used to extrapolate back in time, to determine how many years ago, the rate of expansion was zero. I believe this amount of time will not agree with the accepted age of the universe...
