“At 95 light years away, even if they do find us, none of us will be alive by the time they get here...”
Just because we haven’t figured out faster-than-light propulsion technology, doesn’t mean others haven’t.
They could be here next week, for all we know.
“Just because we haven’t figured out faster-than-light propulsion technology, doesn’t mean others haven’t.”
Except it’s not that “we haven’t figured it out”, it’s that we have figured out it’s basically physically impossible.
Let’s review the possible ways one could travel faster-than-light and why they don’t work:
1 - Acceleration (conventional rockets, etc): Doesn’t work because you can never accelerate a mass to light speed, much less above it.
2 - Wormholes : We don’t even know that they can exist, and if they did, they would take more energy than we can generate to create them, and even if we could create one, we could not traverse them and survive.
3 - Warp drive : Requires creating a zone of negative energy density, which doesn’t seem to actually be possible in this universe.
So that pretty much covers all the bases. Don’t hold your breath hoping for FTL travel, either by humans or aliens.
