Really?

Why is that? Its kinda sad.

Your statement will become more interesting/meaningful when you define the god space/heat death leads you to believe in.

The universe is under no obligation to make sense to you.

Neil De Grasse Tyson (I think)

I mean its so wild that i cant compute. How do you compute with all of this? Can you truly?

Unless you can travel much, much faster than the speed of light it would be very boring.

The more you learn about space, the more you should leave the idea of 'a God'. So what about the 'heat death' makes you think that you lost the 'sauce'? Do you actually study, or are you just an interested reader on Wikipedia or Reddit?

I'm sure someone is hard at work writing a SciFi novel with that title already.

Well, you only need to dig for a very short time - and using humans to dig would be inefficient, anyways.

After the first meter or so radiation is no longer a relevant issue.

It says alone, not solo, so you can interpret it as he was first to be the only one in a lunar orbit. But I guess they just forgot about 10.

Its true that light takes 2.5 million years to travel to Andromeda, as seen by us who are mostly stationary and not doing the travelling. The thing is though, the faster you go, the more time on board the ship slows down, relative to the outside world. If the ship goes super fast, approaching lightspeed, it would look to observers on the outside that time is almost stopped onboard the ship. Or to look at it another way, from the point of view of astronauts on board the ship, the local shiptime is normal, but the time outside seems to get faster and faster. If the ship travels fast enough, you get to watch 2.5 million years go by outside, at which point you are at Andromeda.

If you are able to reach almost lightspeed, you can reach almost any part of the universe within your lifetime (or even years, or days, if you go extremely close to light speed), but, the universe will have aged by millions or billions of years when you get there. For photons, which actually do travel at lightspeed, the journey is instantaneous, as they don't experience time at all.

I think that’s still conjecture

Not bad, not terrible. Meh.

Water is a side product of so many chemical processes that as far as I know there should not be any shortage. Usually water can be fully recycled without worries anyways.

Just fyi with liquids it's commonly called an azeotrope, not a eutectic (which is for solids despite them being the same thing in two different phases).

Primarily different terms because it's different branches of engineering that deal with the two.

I was listening to a podcast a while ago where they were laughing with a guy who (I think) had basically got a Nobel prize or some such for as they put it expanding our ignorance by working out that we actually only really know what 5% of the universe is - because dark matter/ dark energy makes around 95%.

The coolest would be that some stars can have temperature of "barely lukewarm". I know they're brown dwarfs but that counts as stars. And WISE 0855-0714 is not even lukewarm, it's below water freezing point! Makes you really think about... well, what temperature is (anything above 0K). If that's not cool, idk what.

As for the scariest... well, when I was a kid I was afraid about the Sun dying. My tiny brain couldn't comprehend that I won't live for 5 billion years anyway. Used to have nightmares about the Sun frying the Earth. Now it's gamma ray bursts, I suppose. My brain is only slightly bigger now and it cannot understand probabilities and chances well.

Given how long the universe is expected to exist, and taking that into consideration with how long it has already been about. We are so, so, SO early to the party.

Maybe life in the universe IS abundant, but we just haven't caught up to when it is on the timeline.

The "Grabby" Aliens hypothesis is cool too!

We must colonize other planets if we want our species to survive as long as possible

Could already be happening? I could be totally misremembering but doesn’t it still progress at the speed of causality??? Though if so that would mean it might never catch up to some of the expansion? On the other hand … some theorise that we are already in a process of false vacuum decay - that’s what cosmic inflation is?
