You're still describing climate change. Science fiction ideas are fun to think about but our own inability to live harmoniously with nature is going to kill us off before any of those problems become relevant.
I was kind of surprised that comet that's been visible at night was only discovered like a year ago. Crazy to think that would be the warning time of anything coming to hit us
huh? why do people have this innate ability to underestimate what we might be capable of? why do you think its impossible for us to become masters of our own genome?
not getting off this rock means our species is doomed regardless of how 'perfect' we keep earth.
why do people have this innate ability to underestimate what we might be capable of?
Because we can see what we're currently capable of in terms of climate change, and the outlook is pretty bleak
why do you think its impossible for us to become masters of our own genome?
Because even in the best case scenario, this is dangerously close to eugenics
not getting off this rock means our species is doomed regardless of how ‘perfect’ we keep earth.
If we can't keep earth livable, an entire self-regulating planet that's been livable for hundreds of millions or billions of years, what are our chances of keeping anywhere else livable?
there is not a single thing that could wipe out a deep sea habitat that wouldnt also wipe any space colonies. but i dont see anybody arguing for that, despite being far more achievable and practical. also, there is no feasible way for space colonies to be self sufficient anywhere in the near future, so wiping out earth also wipes out space colonies relying on it for supplies. this argument aboOt survivability is absurd.
a rogue planet hitting this one would. i would expect a space faring race to want to move not only to the outskirts of the solar system, but possible attempt venturing to a new one. perhaps multiples.
but go ahead, keep thinking small for some reason. technology never advances dontcha know.
