I don't see any evidence that this is more than sci-fi fantasy. Yes there are (technological barriers). There is no technology that...

I think the Fermi paradox is different than what has been stated here. I think it goes like this: (1) We can already envision our...

I guess it depends on how the Sun-like stars are distributed. The current estimate seems to be about 5-10 billion Earth-like planets...

It's more like tens (or perhaps hundreds) of thousands. With millions of civilizations, randomly spread, there would be a high...
