The Big Crunch? Maybe.
Cinnamon Toast Crunch? No way! Can you explain why kids love that cinnamon toast goodness, I can't. Why? Why? Why?

Humanity will be wiped out billions of years before the big crunch.

Hope that elevates your fear.
Elevates or alleviates?
Gary, I'm a science guy, not a dictionary.
interstellar or even solar system colonies are very unlikely..
actual science considered,

a better option would be to refrain from boiling our planet.. but we might not be smart enough to do that.
Would it be better to build a colony on Mars or Venus?
They say Venus has a toxic gas atmosphere but it's not like we could breathe on Mars either. I heard something about huge pressure on Venus, can someone elaborate or explain that to me, vis-à-vis building structures on the planet which could support human life.
Also - would the relatively low gravity on Mars be a large hinderance to creating a workable human colony? Is this one area in which Venus, with its near-Earthlike gravity would get the nod?
And of course, Venus is closer to the Earth, on average, so fuel costs would be less to travel there - correct? Or is there anything special about the orbits on the three planets that changes this basic math I've done.
Allegedly Venus' atmosphere is 96% gas and has an average surface temperature of 862 degrees, though many global warming skeptics deny this and claim it's perfectly habitable.

Okay, but you can't breathe on Mars either and it is super cold there, so for a colony on Mars or Venus we are going to need to provide breathable air and temperature regulation. Which is more feasible to do, given the other factors differentiating the two planets as well (gravity, distance from Earth, orbital alignment, etc.)
The temperature reaches 70 degrees on a nice day on Mars. Anyway, I think -150 is much easier to handle than +800 and we already have materials than can withstand that. The coldest recorded temperature on Earth is -135.
What's up with that huge mountain on Mars? Something like 3x taller than Everest? But I guess there's no snow or ice on it so maybe it is easier to climb? Also, low gravity, that's got to help a bit. And you'd have to use supplemental oxygen the whole time, so no problem there. Anyway, reason I ask is that I dream of being the first person to summit the big Mars mountain. It sounds far fetched, but I'm young. People probably told Neal Armstrong he was crazy, too, when he said he'd be the first man to walk on the moon.

The universe is so vast that probability requires the existence of an un fathomable level of life sustaining planets, and intelligent species...
Actually, probability requires no such thing and 'vast' is relative.
Perhaps the Universe has 10^25 earth-like planets. Perhaps the probability of life forming on any given earth-like planet is 10^(-35). Then there is roughly one chance in 10^10 or one chance in 10 billion that there are ANY other planets out there that ever had or ever will have life form on them.
The "Oh, but there are so many stars/planets/..." argument is essentially vacuous.
Glad I could help straighten that out for you.
