C) keep the planet we have habitable

[–] [email protected] 23 points 3 weeks ago (6 children)

our planet could easily be wiped by a number of things. if we dont plan for a planetary catastrophe out of our control, our species is doomed.

a planetary catastrophe out of our control

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.

youre still not thinking astronomically. you need to think bigger. i like to at least pretend out technology advances.

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

There are black holes that travel at the speed of light. If one were to pass through our astronomical neighborhood we would never see it coming and it would end our existence so instantaneously that it would be like our species and planet never existed.

[–] [email protected] 3 points 3 weeks ago

I didn't realize they were mobile, that is terrifying.

[–] [email protected] 1 points 3 weeks ago

As long as it's instant then it's not that bad I guess

And you have your head stuck so far up your ass you think climate change is the only threat to the habitability of the Earth when one solar flare gone wrong or object striking the Earth or black hole travelling at the speed of light passing sufficiently close could erase humanity from existence and we would never see it coming. None of these things are fiction and all of them are completely within the realm of possibility. Modern astronomy has documented examples of all of these things happening. In fact the leading theory right now is that the Earth and moon existing as they do is the result of the collision of two objects typically referred to as Gaia and Theia. Theia broke off pieces of Gaia and those eventually came together to form the moon while the rest became the Earth.

As of right now the only thing preventing our species from going extinct due to any of a very large number of astronomical events is luck. But you have no guarantees that that luck will last forever and humanity needs a backup plan.

Uh, nope, you're putting words in my mouth. It's not realistic to worry about mitigating that kind of stuff when we can't even prevent ourselves from cooking ourselves, and several of the things you listed don't even have plausible technical solutions right now. Nice try, though.

Humanity can easily survive a KT extinction event. Sure, 99.999% of us will die, but tens of thousands will still survive.

[–] [email protected] 4 points 3 weeks ago (1 children)

If I use your math of 99.999% dying, only ~80,000 people will survive, not millions…

Thanks, updated comment

If Mars became one "arm" of the human race Earth would still be the heart. Your heart fails and all your limbs are fucked.

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.

[–] [email protected] 0 points 3 weeks ago

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 β€˜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?

[–] [email protected] 1 points 3 weeks ago (1 children)

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.

[–] [email protected] 1 points 3 weeks ago

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.

[–] [email protected] 0 points 3 weeks ago (1 children)

our planet could easily be wiped by a number of things.

Most likely by us, while we waste our limited resources on useless things like spaceships

if we dont plan for a planetary catastrophe out of our control, our species is doomed.

Oh no, how will the universe ever recover from this tragedy?

yep, this is what people resort to when they dont have a real point. 'so what?!' pfft
