- I may not have got this right:
The observable edge of the universe is nearly 14billion light years away, but, because this is receeding from us, its current position must be around 46billion light years away. The actual edge will be further away than that (as suggested in this video). I would agree with Charles Hill that the actual edge will be the point at which the expanding matter finally achieves the speed of light. This all seems to contradict the notion that the universe is just 13.75billion years old.
How about this for an idea: When the matter at the edge of the universe achieves the speed of light it becomes energy (e=mc^2). This energy must go somewhere. How about if it is somehow fed back continuously into the sytem to create new matter? This would make the whole system a continuous process with new matter being constantly created within the universe and old matter being converted to energy at the edge. No beginning, no end. Maybe 13.75billion years is just the age of our part of the universe? The rest ranges from 'new' to however old it would have to be to reach light-speed at the edge.May 14, 2012
- , I am entertaining your theory. If the oldest matter converts to energy when the accelerating universe expansion achieves light speed, the COBE microwave radiation images from the video are not necessarily the echo of the big bang, but actually the output of the continual process of matter dying at the farthest reaches of the universe.
Furthermore, is something at the center of the universe repelling matter (anti-gravity?) to cause this accelerating expansion toward the universe horizon? Where is our galaxy in this continuous process?
Regarding the age of the universe, by Einstein's relativity, time would slow to a crawl (by our measure) within those accelerating galaxies approaching the universe horizon. Do things happen significantly slower in our galactic neighborhood since our matter was formed and began expanding and careening toward the universe horizon in the course of billions of years? If we are accelerating as part of the expansion of the universe, would relative time affect our perception such that the actual age of our galaxy is less than 13.75 billion years?May 14, 2012
- that's a really interesting idea. I think that the matter would not be radiating energy, because in it's own frame it is not moving at near light speeds, and it is not interacting locally with near-light speed (within the local reference frame) objects, so we would not be seeing higher than normal radiation - which should still look like whatever gave off that radiation in structure, even if it is "red-shifted" as heck.May 14, 2012
- Thanks for your comments. Maybe the background microwave energy is the mechanism by which the energy in the system is returned towards the centre? What I like about this idea is the way it allows the universe to have always existed and to continue for ever, even if the actual matter is continuously renewed. This seems, to me, rather more plausible than a 'big bang' start at some point.
No doubt there are problems with this idea, but I think it's good to throw around ideas: there maybe something that triggers a new idea that gets us nearer the truth.May 14, 2012
- wow...just superb.... i would love to see some more of these videos...May 15, 2012
