Stop teasing me, Universe - and show me the aliens already!
- zspade 7y agoJust as long as the universe doesn't show us to the aliens, I'm on board.
- krisroadruck 7y agoCheck out the Dyson Dilemma for a well-reasoned theory as to why it is a high probability that there is no space-faring intelligent life anywhere in our galaxy or even perhaps our super-cluster. https://www.youtube.com/watch?v=QfuK8la0y6s https://www.youtube.com/watch?v=QfuK8la0y6s
- sulam 7y agoThere are holes wide enough to fit a solar system through that argument. Reductio ad absurdum. Here, I'll construct an argument in a similar form. People don't like mosquitos, for various reasons including that they transfer deadly diseases. Therefore the presence of mosquitos says there's a high probability that the planet isn't actually inhabited by us, because we would have killed them by now. After all, we have the technology. Maybe, by the time we get around to wanting to construct a Dyson Sphere, we will have found a better alternative. Maybe they aren't a good idea for any number of reasons (if you need one, read the Cixin Liu "Dark Forest" series). Any argument of the form "X is inevitable but hasn't occurred, therefore Y" first needs very strong proof of the inevitability of X.
- fastball 7y agoTo be honest, I've never really understood how a Dyson sphere would be superior to many nuclear fusion reactors that you can move around / turn off and on / build more of / etc
- michaelmrose 7y agoThe sun is 99.9% of the mass in the solar system. Most of the rest of the mass is in Jupiter. If you are ultimately bounded by energy requirements then solar is where most of the available energy is even if you literally cannibalize the gas giants.
- mihaifm 7y agoIn this case it’s highly unlikely that there out there, that close, existing simultaneous with us. 4 billion years ahead of us...they’re either long dead or non-existing.
- rossdavidh 7y ago4 billion years, eh? Just about the amount of time we've had life here. Maybe they already colonized us, and we're descended from them.
- dogma1138 7y agoUnless they colonized us with panspermia it’s about as likely as “intelligent design” they surely put in a lot of work in hiding the fact that they came here including engineering 3 billion years of evolution. While possible seems a bit inefficient.
- sebazzz 7y agoLet's just say a part of Mass Effect is real and there are actually many civilizations right now. What are the chances that we could even know they exist with the current technology?
