New Big Bang Cosmology

...but I'm still not buying what you're sellingnonsense is relative and I don't hold the monopoly on it. Are you saying that a bubble skin doesn't have an inside or outside surface ???on a side note, I was just reading somewhere that the universe is estimated to be 172 billion light years acrosss yet only 13.5 billion years old so going by what we discussed earlier about a particle starting it's journey at t=0 how can this be especially if light speed supposedly can't be exceeeded ???...unless expanding space carrying matter in the initial stages of the universe exceeded the supposed maximum velocity of light speed by a considerable amount as seems to be the theorybut getting back to bubbles, the thickness of it's skin as viewed from inside the skin itself gives you no indication of the size of the bubble as viewed from a point outside of it especially if (viewed from inside the skin) light bends around the inner surface and you can't actually see the outer surface as the light hasn't caught up to the expanding outer edge. That would leave a big sumthing we don't have a frame of reference for to fill the bubble itself......don't know much about riemann geometry but I will look it up and try to assimilatethanx

Hello Gup20 and welcome to the forum!I have to admit that I had a few problems with your post as it seemd to contradict what we know about relativity in a number of places. Actualy, from our perspecive, time on the faster moving outer galaxys would be much SLOWER.From our perspective it DOES appear that everything in our hubble volume is moving away from US at at increasing distances. Physiscs has shown that this is because Space itself is expanding, It looks the same way from every galaxy so no galaxy can be said to be the unique center of the universe.It also appears that our universe is finite. This is because as space expands, more and more galaxys will be moving away from us at a faster and faster speed. Once these outer galaxys are moving away faster than the speed of light they dissapear entirely and leave our "hubble volume". {edited to add} this disapearance is not sudden though as they have been geeting dimmer and redder due to the doppler effect.In a few billon years space will have expanded to such an extent that the only other galaxy visible (or reachable) from ours will be the andromida galaxySo even though it may SEEM like we are the at the center of the universe and even though it may SEEM like the universe is finite. The evedence actualy points the other way. The universe is infinite, has no unique "center" and no "edge". No, again you have it backwards. Time would seem to move more QUICKLY for us. Because as things move time slows down for them.See this post of mine for more on relativity and how observers cannot tell if they are moving or not merely based on time dialation:http://EvC Forum: Purple dosn't beleve in relativity -->EvC Forum: Purple dosn't beleve in relativityThis message has been edited by The Dread Dormammu, 12-08-2004 06:00 AM

Because space continues to expand and it's expansion is accelarateing. hence our hubble volume is much larger than 13.5 billion light years in radius.Just becase an object in space cannot accelarate to the speed of light or faster that doesn't mean that SPACE ITSELF is limited by the same constraint. In my previeos post I talked about how distant galaxys are becoming invisible becase they are accelarating away from us and leaving out hubble volume.This message has been edited by The Dread Dormammu, 12-08-2004 06:05 AM
