Small-Scale Question Sunday for January 14, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

But that leap - from ‘they exist’ to ‘they exist and actually have visited us’ - doesn’t seem as great as you suggest.

This leap is literally measured in light years. Humanity would need a massive upgrade of its spacefaring technology to reach even the nearest star. Our furthest-reaching satellite broke down in less than 50 years and is too slow to reach Alpha Centauri even if we fired it in the right direction. A constant-acceleration drive that is also powerful enough to routinely spend enough delta-V to get close to the planet instead of hanging around Kuiper Belt? We're very far away from building something like this, but would notice a craft capable of this kind of manoeuvres.

I agree it’s a huge technological leap. I’m saying that for most of the atheist humanity fuck yeah space is cool I fucking love science crowd, aliens visiting earth wouldn’t shatter their model of the universe. (And the same, of course, is true for the religious).
