Ever since the discovery of icy ocean worlds like Europa and Enceladus within our solar system, the scientific community has been captivated by the potential for life beneath their frozen surfaces.
These subsurface oceans have intrigued astrobiologists for decades, as they ponder whether the conditions necessary for life exist in these hidden waters.

Interesting. I’m so eager for them to come up with more conclusive evidence at some point.

Is anything other than the moon and mars habitable?
reply
Planets are just really deep holes that are hard to get out of. Just use asteroids to build houses in space instead

Astroids dont have a steady orbit...do they?
reply
Anything can have a steady orbit if you do the math and make it have a steady orbit.
Probably wouldn't have the asteroid belt, or rings on Saturn, if asteroids couldn't have a steady orbit.
However, I would grant you that the human inside the asteroid would probably mess with that, but they would also expend energy to keep it on course.
Also if we got big enough, we could all join homes in a ring (you could think of it like the first layer of a dyson sphere) and all have a steady orbit together and correct together.

Seems like a lot of work when there is the moon or mars.
reply
No it would be the same work because the moon doesn't have an atmosphere and neither does Mars and nothing can grow on Mars without planet wide changes (literal intentional climate change) so you have to build these self contained habitats either way.
Whereas with an asteroid, you can just heat it up (by bringing it closer to the sun) and the denser part will go to the center and the less dense part will be on the outside, then you put this droplet of water in the middle, seal it up and heat it up again and boom big iron and nickel bubble you can decorate and put a door on and air cycling system etc.
Figuring out orbits and self correcting is a computers job.

I had never heard this strategy before. That's really interesting.
Too much work.
Yes!
For one, pretty much any moon or asteroid are as inhabitable as those two bodies.
More excitingly, there's a layer in the atmosphere of Venus that has nearly breathable air, as well as reasonable temperatures and pressures. There's no water on Venus, so that would have to be delivered somehow, but people have speculated about floating cloud bases that could be inhabited.
reply
Which one is closer, Venus or Mars?
reply
Venus is closer, but I think Mars may be easier to get to.
reply
hhhmm.. They also have to time their departure to arrive when the planets are aligned, right?
reply
I'm not sure, but the explanation was something something orbital mechanics.
reply
If mars is on the other side of the sun, it would be a while before it swings back around. I think?
I highly doubt we will find an independent emergence of life in the same solar system (if a meteor/comet transferred biomaterial from one body to another, that would not be "independent").
If we do, however, that would be an observation (albeit a singular one) suggesting that the universe might absolutely be teeming with life (though not necessarily one that can communicate).
Or, the "precursors" seeded the universe with life according to some specific plan, and that plan called for multiple "experiments" in this particular system.
reply
This is so neat, I think life exists out there! It would be neat to find life on another planet sometime in our lives. Life is out there, we just haven't discovered them yet/ or they haven't discovered us yet.
reply
The universe is full of secrets, my curiosity really kills me to discover them and know if there is any form of life.
