::Both rational though and our genetic programming says that we need to spread more to avoid the risk of extinction. Note that Mars guarantees nothing: Sun will go nova in just five billion years and destroys all inner planets. That's the deadline to moving to different solar system or at least moons of Jupiter. We would need to move to Mars sooner, as Earth will get too hot (yes, even if we stop current episode of climate changes). Also, that's assuming nothing will crash into our solar system when {{w|Andromeda–Milky Way collision|our galaxy will be crashing into Andromeda}} in 3.75 billion years. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:46, 16 March 2019 (UTC)

:::The travel-into-space efforts seem to either be "right now!" or "that's stupid" when it seems a more rational approach would be, "let's just make sure we're always working on this a little bit." [[Special:Contributions/162.158.78.100|162.158.78.100]] 17:30, 16 March 2019 (UTC)

::::I second that. Let's stop worrying what will happen in "just five billion years". Anything can happen between now and 5 Ga from now, including Earth being ejected into interstellar space (goodbye, Sun! goodbye, life!). We've already done a lot to avoid extinction in the last few thousand years, and we'll continue that effort; however, being unable to learn from an example, we can make a fatal mistake anytime without realizing it until it's too late. Or a random big event (internal or external) could wipe us all. Or a natural long-term trend (in human timescale, not billions of years) that we can't possibly adapt to. So research what we reasonably and affordably can and hope for the best :-) -- [[User:Malgond|Malgond]] ([[User talk:Malgond|talk]]) 10:56, 18 March 2019 (UTC)
