Space / Time Questions

[leee (Thomas)]

These are probably simple questions - but. If the universe is as far as we can see (the longest light that has so far, reach our eyes) which is 45 billion light years + or -
Then will we - have to amend that distance every year, because "new" light will have arrived for us to 'see' ?

Secondly If all mass warps - time/space -such as we do and our moon, sun etc.
Then the Universe must look like a chaotic mess. and what happens if two object are close together. Each creating their own warp, then creating another, due to their close proximity ? And With 'Warps' everywhere, in all directions, Overlapping ? Each Galaxy must create their own gigantic Space/Time warp as well ?

Lastly . If light wraps around a mass - then light we see from like 19 billion light years ago -must have warp around billions or objects , billions of times by the time we see it.
By that time, do we even know where it came from ? its direction ?

Yes.. but effect is not THAT significant, so we ~know where light came from. Universe is actually quite empty and masses are very far away from each other.

To see Einstein's rings, you really have to have a very large instrument (Hubble Telescope, for example).
As to CBM..Universe was once soaked in it.. so it is coming to us from everywhere.
