Hey all
As is my way I pondered what would happen to light (and other emr) when it reaches the edge of the universe.
First one must assume the universe has an edge.
Anyways I figured there is possibly two cases
1./ The universe is expanding at the speed of light so nothing ever reaches the edge
2./ As light reaches the border between the known and the unknown it must encounter an impedance mismatch.
Working on 2, I would assume the edge of the universe would be a perfect mismatch, in that everything that reaches it reflects back. Would that make it a perfect mirror?
Given that one must think then that perhaps some of the cosmological features we see in the universe are in fact reflections.
If the reflection is not perfect but in fact diffused, then perhaps that would fill the universe with a even glow of electromagnetic radiation in much the same way as white walls help fill a room with light, even the dark corners where the bulb is eclipsed by a chair.
Hmm CMB?
