i dunno why people think aliens visiting earth is such an impossibility. if the universe is infinite, there must be plenty of other intelligent lifeforms out there. surely, humanity in 100,000 years from now can figure out FTL travel?
a) The Milky Way alone has billions of stars with an unknown number of planets. To call earth a needle in a haystack would be a ridiculous understatement.
b) Just faster than light doesn't cut it. Even if you were able to travel a hundred times the speed of light (which would completely break physics as we know it), traveling across the Milky Way in a straight line would still take you like a thousand years. Traveling to the Andromeda galaxy would take you 25,000 years.
c) There's still the very real possibility that FTL travel is straight up impossible (for every life form everywhere) because it would require literally infinite energy. If we could theoretically achieve 99% the speed of light we could travel to other solar systems, but our range would be very limited.
