Where are the aliens?
Fermi wasnt a troll.
you’ve got the option to believe in aliens and also recognize that science requires actionable data.
But what if both Fermis paradox and the alien enthusiasts are correct?
Lets start with the basics.
Thats a long trip to make for some small odds.
But what if we simplify things a bit.
And, according to them, about 94% ofeverythingis out of our reach.
The idea of location is a moving target, so to speak.
Thats because the universe is expanding.
This makes visiting the vast majority of all galaxies impossible.
As Siegel puts it:
As the universe expands, the space between all unbound objects increases over time.
Beyond distances of ~14.5 billion light-years, spaces expansion pushes galaxies away faster than light can travel.
This simple statement puts a lot of things into perspective.
So, what does that tell us about any trips to our next door neighbor Andromeda?
If Einstein and the laws of physics are correct, nothing can travel faster than the speed of light.
And that means that trip would take 2.537 million years at the universes speed limit.
Chances are, we wont be meeting any space aliens unless theyre already in our own galaxy.
