I respect your position but I completely disagree. We are so far off from needing to worry about the sun dying out. We should be focused on stopping and reversing climate change.
It's not just about the sun dying out. A large asteroid could strike at any time and wipe us out. If that is going to happen on Earth with probability p and we make it to Mars then our chances of going extinct due to that cause shrinks to less than p -squared (it's less than p -squared because Mars is smaller than Earth), which is many orders of magnitude smaller than p . Diversification is extremely important to our…
The chances of being wiped out by a super volcano or asteroid impact over the next 500 years until we solved the sustainable energy problem and a stable ecosystem are rather small.
