These articles should spend more time trying to explain the scale of galaxies and superclusters, plus the sheer number of stars vs. physics. That puts in so much perspective: even if we had warp 11 drives it would be essentially impossible to look for alien life on every star system. We’ll never find each other because the universe is too damn big.
- nadermx 3y agoThat's assuming that's the only mode of travel. There could be worm holes, or things we can't imagine. Also if the goal was to find life, searching would not be optimal. It would be better to launch pods that self expand to nearby planet, make their own pods, and go to the next nearby planets.
- demondemidi 3y agoEven if there is a wormhole or some crazy sci-fi thing we haven’t thought of, there are a million trillion stars. Basically invisible. Unless you suggest some technology appears that allows an entity to travel to every star and observe it for billions of years. I’d love to hear a sci-fi proposal that covers this without invoking omniscient gods or the supernatural.

- bsmith 3y agoMultidimensional beings that transcend time and/or space. Not necessarily dieties, but it kind of is from our perspective. Another night be that consciousness exists at many physical levels. Just like you are made of trillions of automata of cells and bacteria, which are played out by proteins and DNA, maybe the universe is a single consciousness, and we are but one part. Or a part of a part.
- saulpw 3y agoThe universe is so vast, that I think even self-replicating probes traveling via wormholes would not be able to cover even a tiny fraction of the existing planets before their suns die out. The universe is really really really big.
- demondemidi 3y ago200 billion trillion stars in the universe. 13.7 billion years old, with a window of detection of about 1,000,000 years (evolution to self-extermination). Maybe I'm just a dumb human, but I really don't see why a supergenius race would invest the resources in scouring the universe. Unless it was their manifest destiny. In my head a narrative to address this crosses from sci-fi into fantasy.

- bsder 3y ago> We’ll never find each other because the universe is too damn big. Intra-galaxy is certainly not too big. Even at slow, sub-relativistic speeds, our local galaxy should be fully colonized by now--whether by self-replicating automation or life. This is the paradox.
