  • You’re including a great list of things we have or do have to look into to solve before space is trivial. You’re omitting a lot of the problems of underwater, or even above water colonies. I do agree that colonization of space comes only if we can make it self-sufficient, as getting all the resources from a gravity well makes it ridiculously costly and limited. I disagree on how any of the problems have no solutions though, as they’ve been discussed even before I was born, and I’m old. 🫤

    Will humans change by necessity and by exposure? Of course they will. The Expanse did a good job of suggesting early changes to those living in low gravity conditions (which is probably the biggest thing to solve, not radiation or material sources). And after even longer they will change even more, making the different places become subsets of the species as we diverge.

    Thanks for the link, I could not remember where that site was from so long ago, but it’s a great collection of lore and speculative ideas.

    We just disagree on what can be done. I can’t imagine the scifi visions of underwater places that ignore how a small crack leads to instant crushing, or the constant corrosion that has to be fought against. On the Moon and Mars we’ve got the dust that is still a questionable thing on how to handle (electrostatic charges were the last I saw that seemed like they may help some). If you don’t have to rely on Earth for most supplies and you find ways to counter radiation (a few meters of slag works, not practical for a ship due to the mass, but a station isn’t a problem). Rotation may solve a lot of the problems with zero G, but we need to do more research on site before we can just accept it’s unsolvable.

    It may not matter and we may not be around that long for it to be a factor anyway, but assuming we are, we have to move on from the Earth, as the window of habitability is not that long. Huge for us at human scales, but cosmically we’re way past the halfway point.


  • Your list of other places to colonize are easier than a difference of one atmosphere and controllable environment? That’s funny. I never implied it would be easy, I said the opposite, and getting into space is a big part of that. And there are dangers to figure out. But a hull leak in space is far safer than even a few hundred meters under water.


  • Maybe. We never got far enough to really test the waters that much. I think that it’s more possible than flying cars or living on Mars, but it would take huge effort, and my opinion is the window of opportunity is all but shut now. But why should we? If for no other reason than because of the “eggs in one basket” metaphor. Even past climate change and impacts, this Sun won’t last forever, and if we don’t find ways to move on, all life that we know of is gone.

    Maybe that doesn’t matter in the end, after all the universe also ends some way too. I think even if life is everywhere, it’s all unique, and so are we, good and bad. But we obviously don’t treasure what we have much, and maybe it’s better we don’t spread the same bad we do to Earth and ourselves elsewhere. It’s possible we simply advanced before we were mature enough to understand what we could stand to lose.

    Flying cars was a scifi delusion that didn’t consider all the problems that come with it. What would be a more rational “this was predicted and never came about” would be social constructs like safety nets and betterment of society for all, as well as improving our management and use of the Earth. That should make us mad, not that we don’t have flying cars buzzing (and falling) in the sky.

    It just hit me that we did for flying what we should have done for ground. Make it almost all mass transit.
