Comment on Bezos plan for solar powered datacenters is out of this world… literally
brucethemoose@lemmy.world 3 weeks agoI have, but I’m also concerned that humanity got “lucky” so far and that this won’t happen again. There are theories positing that there are several blocking “gates” to civilization, and humanity passed an exceptional number of them already.
It’s reasonable to assert that’s a misleading, human centric perspective; but I’d also point out that the Fermi Paradox supports it. Either:
-
The conditions that gave birth to our civilization are not exceptional, and spread intelligent life is hiding from us (unlikely at this point, I think)
-
They are exceptional, and we just happened to have passed many unlikely hurdles so far (hence it is critical we don’t trip up at the end here).
-
They are not that exceptional, and there is some gate we are not aware of yet (which I have heard called the Great Filter).

Well that’s all true, we don’t actually know what the real filters are, are we already past them, or are they still ahead of us? Certainly people have speculated about this for a long time, and I won’t pretend to have any more real answers than anyone else. But honestly, I’d have a hard time believing that the really rare event, that the great filter lays somewhere between the development of the brain and the development of the kind of intelligence humans have. It just seems like a relatively small jump (relative to all the other hurdles) between many of the smarter animals on earth and human beings. For example, many species use tools a whole lot actually. Only a few other species actually make tools or alter them to a large degree, but you know, give it 10 million years and see if that changes. Likewise, many species have languages, some species even give themselves names, so they can intentionally address other individuals in their social group.
If you don’t mind a bit of total speculation on my part, in my opinion, the explanation to the Fermi paradox is actually pretty simple, there really is no paradox. Intelligent life is probably relatively common in the universe, the reason we don’t see aliens all over the place is that intelligent life thrives too well for that. Once a species is capable of traveling other stars, it’s just a matter of time before they settle most of their galaxy, like within a million years (which is very quick on evolutionary scales). We’re just the first intelligent life in this galaxy, we can assume this because if there were others, they’d already have colonies right here on earth, because it’s a great planet.

Yeah, I buy the filter being early. That does seem like a freak accident, even with all that time for it.
But on the spread of civilization, this is why I love Orion’s arm: if a civilization like ours makes it another few thousand years, it’ll basically expanded in a bubble at a high fraction of the speed of light, meaning civilization should have spread across galaxies by now:

And the fiction, even as wild as it is, gives the somewhat unsolved Fermi Paradox a lot of thought:

I particularly like the ‘Ginnungagap Theory’ that, perhaps, there’s some unknown barrier to expansion.
