I know it’s probably something I would not understand, but when Scientists say in an article, they are peering back into the origins of the Universe with the JWST, I wonder what happens in 20 or more years when another telescope is out there which is 100 times more powerful than the JWST and can see even further back in time, meaning how does anyone know when the end of the universe has been reached.
At some point, the red-shift of the light will be so far under the ‘infra-red’ (read: heat), part of the spectrum that it will be undetectable. Then you will have reached the edge of the known Universe. There may very well be ‘stuff’ out there beyond that physical limit, but we won’t ever see it in this lifetime................................
If you believe in the Big Bang, and the estimates of when the Big Bang occurred (based on red shift observations) then you wouldn’t be able to look back more than about 15 or 16 billion years.
When you finally see God
You can only look back to when light first appeared in the universe, which appears to be 13.? billion years ago. Nothing to look at before that no matter how powerful the telescope.
There will be a line of cars and a Border Customs station.
Thats no longer a real important question, since the 'end of the internet' was discovered right here on FR.
