Still not solving communication speed limits
- pavel_lishin 11y agoI think the previous commenter was saying that the communication speed limits may not be a problem that can be, or needs to be, solved. If the speed of light is the ultimate speed limit, technological civilizations may just have to accept it and work within that limit. Just because a method of communication is slow doesn't mean it's not worth using.
- DasIch 11y agoIf that limit can't be broken, it would massively slow down space travel though. Our civilization currently consumes more resources than can be replenished. What if other civilizations have the same problem and can't travel to other planets before resource starvation comes in?
- krapp 11y ago> What if other civilizations have the same problem and can't travel to other planets before resource starvation comes in? They probably die.
- nine_k 11y agoTraveling to other planets is relatively easy; in our system it takes just a few years using the cheapest chemical boosters + ion engines. A nuclear rocket engine (quite feasible) would probably lower the travel time noticeably. Communication delays in the range of a few hours maximum are not a significant problem either. It's traveling to other star systems what is hard. OTOH we live in a relatively sparsely populated neck of galactic woods; thicker clusters of stars exist with much shorter interstellar distances. Conditions there are usually deadly for us, though.
- pavel_lishin 11y ago> If that limit can't be broken, it would massively slow down space travel though. Yes. So? I reiterate my previous argument.
