redpill me on extraterrestrials
the visible universe is 90 billion or so light years across, something humans can't truly appreciate. Have advanced alien civilizations existed in the past? Probably. Do aliens exist now? Probably. Have they visited earth or will we ever visit them? Probably not. To even go to other potentially habitable worlds we need generation spaceships that can support at least 100, 000 humans for a million years or so. The same would be said for them would it not? You need to be able to appreciate the size of the universe to realize we most likely will never find advanced alien species.
It's actually possible that we're the only intelligent species in the universe, large as it is. Circumstances have to be extremely specific for life to develop to that stage. Tons of microbial life out there, though.
this could also be true. But considering how vast the universe is earth really isnt that special.
"Thus, while scientists might see a spot that lay 13.8 billion light-years from Earth at the time of the Big Bang, the universe has continued to expand over its lifetime. Today, that same spot is 46 billion light-years away, making the diameter of the observable universe a sphere around 92 billion light-years. "
thats a very true possibility. but 100 billion galaxies is a lot. you could potentially have 1 million clone planets of earth.
all im saying is there probably is life as we know it out there, but its too far away to matter. or its existed and run its course already. 13 or so billion years is a long time
Here's your red pill sir.
Better keep the story as a big "maybe" right now.
