  • I mean, saying it would take half of forever with existing technology, when we do not have the technology to do it in the first place, seems a bit redundant. There are any number of hypothetical technologies for travel to relatively nearby stars that, while we don’t have them presently, at least do not violate physics and are more an issue of requiring a civilization of much larger scale than ours to afford to build them rather than one of if they’re physically possible.

    An analogy I once saw was this: suppose you were to go back in time to meet a medieval blacksmith, and you show him the blueprints for a modern jetliner. You might, with a lot of explaining of the relevant physics and engineering behind all the parts, be able to convince the guy that the machine could work if constructed. But, he’d have no idea of the process for how many of the parts are made, or the materials they’re made from, and if you included all that information too, the whole process would be so expensive and the size of the economy back then so small that in all likelihood, not even the richest kingdom on earth in his day could possibly afford to actually build and operate one. However, if the blacksmith took all that information and concluded “this can never happen, it’s just too hard”, time would prove him wrong.


  • Terraforming would seem a bit unnecessary if you can send a crewed ship there. Manned interstellar travel, unless we’re wrong about the whole speed of light thing, is going to take decades at least to reach the very nearest stars (I’d imagine that it is more likely we’d go to those stars first, and only reach Trappist when people from those stars later launch their own ships, until eventually the outer edge of settled space reaches 40ly).

    That implies that, if you can send some colony ship to another star, you necessarily have the technology to build a space habitat that can sustain large numbers of humans in sufficient comfort to run a small civilization and all relevant industry, self-sufficiently using only the materials available in space from asteroids and such as inputs. You have this tech first, because the colony ship is itself just one or more of these habitats, on top of some massive propulsion system.

    As such, why even bother with terraforming planets? That’s a process that may potentially take millennia to truly finish, longer than it took your ship to even get there with some of the possible propulsion options, will only be viable on a fraction of worlds, and will still get you a place that probably does not have an earth like day or gravity or any number of other differences. You would then be back in the bottom of a gravity well, which requires a ton of energy expenditure to get back into space again. Why not instead, find some asteroids and comets in your target system, there’s probably going to be some around somewhere if our solar system is any indication, and build more of those habitats as needed.





  • While I do agree, I also find that even though I find VR a lot more intense and enjoyable than any flat screen game I’ve played, I also only rarely use mine even still. There’s something about it that seems to make it a hassle to use casually somehow, between actually getting the headset straps feeling comfortable, getting the passthrough cables plugged, launching driver programs on both the pc and the headset just to get to steamvr. It’s not a problem at all if I’m feeling specifically like doing VR stuff for a couple hours as it doesn’t take that long, but if I’m recently home from work and want to just chill for a bit without really knowing what, even that inconvenience means that the VR stuff basically never gets used for me.

    My current VR headset feels a lot more polished than my previous, older one, or previous experience with earlier devices owned by people I was visiting, and admittedly I bet it’s probably a bit smoother on standalone than on pc passthrough like I go for, but I feel like to really take off, putting it on is going to need to not feel like setting up a printer whilst wearing a box on your head.
