No.
The timespan of the whole of Humanity will be just a mere blip in the billions of years the universe will exist.
The universe is unimaginably big.
The spotlight effect is strong here.

- 4ndrewl 11mo agoI mean if their blink-of-an-eye existence corresponded with our blink-of-an-eye existence and they could pinpoint us at a distance of 20,000,000,000 _light years_ then sure, why not I guess?
- keepamovin 11mo agoI get you, but what if we are talking not individual life to individual life but civilization to civilization? Anyway I think you are considering the correct details to pin down the maths!
- IAmBroom 11mo ago"Corresponded" is an excellent verb choice, since their existence must be 20BY before or after ours...
- Yizahi 11mo agoThere is no way to detect our civilization bio signatures and technology signatures from more than a few closest stars range at most. None at all. Not even with magic. There is likely hundreds or thousands of isolated alien worlds in the galaxy, the is no point in getting to them just because they they are alive, because of the next problem - it is absolutely mind boggling what amount of energy and technological advances are mandatory to even short interstellar travel. If you can solve them all, your civilization are practically gods. Why would they concern themselves with some early stage civilization, to which they must travel for millennia in an iron box? This would also mean they have solve immortality btw, or they would all die in transit.
