(Hi I'm actually a physicist believe it or not)
BrokenGlass

( That is awesome)
ArtIsArt

(And I still cry over Curiosity.)
BrokenGlass

( I'm a highschool drop out with basically only random science I've picked up because awesome. so An actual brain talking about space with me is a yay )
ArtIsArt

I'm not an astrophysicist by a long shot but I love my field.
BrokenGlass

any science is better then none?
BrokenGlass

bounces
ArtIsArt
8 years ago
True.
ArtIsArt

Mars is neat because it might have had primordial life once. Now its core has solidified, though, so no magnetic field to keep out cosmic radiation, which blew its atmosphere away.
BrokenGlass
8 years ago
That is really cool actually.
ArtIsArt
8 years ago
It's why small planets, even in the goldilocks zone, can't support life.
BrokenGlass
8 years ago
Like I know it used to have oceans right? Because their cores go out?
BrokenGlass
8 years ago
wow Two different thoughts at once there sorry
ArtIsArt
8 years ago
Yeah, their cores freeze.
ArtIsArt
8 years ago
And yeah, used to be blue and beautiful.
BrokenGlass
8 years ago
I wonder if there would ever be a way to I donno reheat a core.
BrokenGlass
8 years ago
See i have no idea if that was a stupid thought XD
ArtIsArt
8 years ago
Maybe with nukes but that'd also, y'know, irradiate it.
BrokenGlass
8 years ago
hums So it's not actually a silly thought.
ArtIsArt
8 years ago
Kinetic bombardment could also work!
BrokenGlass
8 years ago
Because energy is hot. nods
ArtIsArt
8 years ago
Yep!
ArtIsArt
8 years ago
But nothing will bring the atmosphere BACK.
BrokenGlass
8 years ago
bounces Ok saying we could somehow relight a planet....
♔ carrot king

:-o nothing can be done for the atmosphere? :-(
BrokenGlass
8 years ago
Ok what makes an atmosphere?
ArtIsArt
8 years ago
We still can't bring back an atmosphere.
ArtIsArt

The release of gasses as the planet cools.
BrokenGlass
8 years ago
head tilt
BrokenGlass
8 years ago
Well. Then why couldn't re just release those needed gasses?
ArtIsArt
8 years ago
Because they were alreasy released.
ArtIsArt
8 years ago
The stone doesn't have any more.
ArtIsArt
8 years ago
Plus we'd have to melt the whole planet to slag.
BrokenGlass
8 years ago
Yeah. But I mean. I mean Just releasing those gasses ourselves.
ArtIsArt
8 years ago
Where would we get them?
BrokenGlass
8 years ago
Well what are the gasses?
ArtIsArt
8 years ago
Oxygen, Nitrogen, Carbon, and Hydrogen.
ArtIsArt
8 years ago
Mostly.
ArtIsArt
8 years ago
We could raid a star, but that's probably a bad way to do it.
BrokenGlass
8 years ago
we can make those though can't we?
ArtIsArt
8 years ago
Sorta.
ArtIsArt
8 years ago
We can make trace amounts of highly energized and/or radioactive versions through fission.
BrokenGlass
8 years ago
I'm saying this shit like it's simple. i know.
ArtIsArt
8 years ago
But fission reactions are not easy to maintain.
ArtIsArt
8 years ago
We could probably use our excess atmospheric carbon, and there's oxygen and hydrogen in mars' polar ice caps, but nitrogen is in a super delicate cycle on earth.
BrokenGlass
8 years ago
I'm not even thinking making them all at once. just we know how to make those gasses individually don't we?
ArtIsArt
8 years ago
They're basic elements, so can only be produced by fusion or fission.
BrokenGlass
8 years ago
oh ok hums
BrokenGlass
8 years ago
It sounds like Nitrogen would be the hardest to get.
ArtIsArt
8 years ago
Yes.
BrokenGlass
8 years ago
I'm pretty much sitting here like. It actually sounds possible but insanely fucking hard to the point of laughably never going to happen with what we have currently.
ArtIsArt
8 years ago
If we nuke it to slag it may release enough gases, but it'll still cool again.
BrokenGlass
8 years ago
Would slagging something else work if we stole the gasses?
ArtIsArt
8 years ago
And yeah, pretty much. Until we can tap stars for gases, we can't easily remake an atmosphere, so we're better off searching fr life-supporting exoplanets.
ArtIsArt
8 years ago
Could but transporting's an issue too.
ArtIsArt
8 years ago
We've been seeking goldilocks exoplanets for about 30 years, and they're hard to find, but we've found several.
ArtIsArt
8 years ago
Including one around Alpha Centauri.
BrokenGlass
8 years ago
I was just following that thought mostly There would be insanely easier ways to waves hand I donno colonize.
Agent Dad
8 years ago
Long way away though
BrokenGlass
8 years ago
The issue with That thought line is the Travel more then anything.
BrokenGlass
8 years ago
So lets follow that.
ArtIsArt
8 years ago
Our best bet would be nuking the planet into slag in such a way that the energy levels on the surface were appropriate for the breakdown of calcium and silicon into C, H, O, and N.
ArtIsArt
8 years ago
But that's REALLY HARD.
BrokenGlass
8 years ago
All of it is really hard. and it's awesome.
ArtIsArt
8 years ago
We could also siphon gas giants, maybe.
BrokenGlass
8 years ago
oh!
BrokenGlass
8 years ago
Thats a thought
ArtIsArt
8 years ago
But that's not easy either.
ArtIsArt
8 years ago
Currently people are working on occluders and telescopes to analyze exoplanets.
BrokenGlass

nods
BrokenGlass
8 years ago
Travel.
ArtIsArt
8 years ago
Yeah.
ArtIsArt
8 years ago
It's not easy.
BrokenGlass
8 years ago
bounces What would be the easiest Way to figure out?
ArtIsArt
8 years ago
But it's easier to sustain a ship for generations than to terraform a planet, in theory.
BrokenGlass
8 years ago
Sure. Generation Ships would be the simplest...in some ways.
ArtIsArt
8 years ago
Well, we've got these AWESOME microwave emission impulse engines now. They work basically forever on principles we still don'
ArtIsArt
8 years ago
*don't fully get, but they work.
ArtIsArt
8 years ago
And they can very slowly accelerate something forever.
BrokenGlass
8 years ago
We still don't know how gravity or brains works so i'm not shocked
ArtIsArt
8 years ago
So you push something out of atmosphere and it's got decent speed and then you switch to these things and you can just go faster and faster forever.
ArtIsArt
8 years ago
Until things start getting relativistic, anyway.
ArtIsArt
8 years ago
There are speed limits and other forces involved.
ArtIsArt
8 years ago
Gotta push against radiation and cosmic background junk.
ArtIsArt
8 years ago
But we can do it.
BrokenGlass
8 years ago
It would still take....insane time.
ArtIsArt
8 years ago
Yes.
ArtIsArt
8 years ago
Generations.
ArtIsArt
8 years ago
And a large ship to support the project.
BrokenGlass
8 years ago
And it would need to be an Ark.
ArtIsArt
8 years ago
But it's possible, we just need to know that our goal is worthwhile.
ArtIsArt
8 years ago
Basically, yeah.
ArtIsArt
8 years ago
Though we'd probably want to minimize invasive species, so we'd mostly ship humans and food crops.
BrokenGlass
8 years ago
Embryos
ArtIsArt
8 years ago
Could work, but we'd need to have educated people on board as well.
ArtIsArt
8 years ago
It'd be a little society.
BrokenGlass
8 years ago
And it would take a hell of a lot of People willing to die on a ship and have their children's children's children die on that ship
BrokenGlass
8 years ago
And hope The generation that gets there Gives even a Little damn
ArtIsArt
8 years ago
Yeah.
ArtIsArt
8 years ago
It's better to work on preservation of our current planet.
BrokenGlass
8 years ago
Well yeah.
BrokenGlass
8 years ago
but Space
ArtIsArt
8 years ago
I knooooow it's so cool!
BrokenGlass
8 years ago
Preservation will be another plurk because more science yes.

If you got your GED you could always go to uni someday, study this stuff.
BrokenGlass
8 years ago
laughs Working on it. ive actually graduated ged class three times....
BrokenGlass
8 years ago
it's getting to a Testing center for the Big test thats fucked me.
ArtIsArt

/nods
BrokenGlass
8 years ago
I'm hoping to get it done this year though and start applying for schools for the coming year.
BrokenGlass
8 years ago
I'm planning on softer sciences ( Anthropology )
BrokenGlass
8 years ago
But i may find harder sciences more to my liking in practice who knows?
BrokenGlass
8 years ago
I Just. I like thinking about This sort of thing.
ArtIsArt
8 years ago
It's fun!
BrokenGlass
8 years ago
Think tanking about anything is fun
BrokenGlass

Lets try another Travel thought. Generation ship is out for the moment. Whats another way we could pull it off?
ArtIsArt
8 years ago
Relativistic ship.
BrokenGlass
8 years ago
Fast enough you mean?
ArtIsArt
8 years ago
Time dilation would make time flow slower for the astronauts, and it'd eat up space like whoa.
BrokenGlass
8 years ago
black hole energy?
ArtIsArt
8 years ago
What do you mean?
BrokenGlass
8 years ago
waves hand Any time Time flow comes up in just about any Sci-bullshit stuff at least when it comes to time in one place moving slower it has to do with black holes in some way.
BrokenGlass
8 years ago
like I said I know very very little
BrokenGlass
8 years ago
quietly googles Relativistic
BrokenGlass
8 years ago
So you're talking Warp drive?
ArtIsArt
8 years ago
Basically!
BrokenGlass
8 years ago
but could we get it to work is the question.
ArtIsArt
8 years ago
If you get the aforementioned engines going long enough, you theoretically can.
BrokenGlass
8 years ago
Could our bodies deal with it though?
ArtIsArt
8 years ago
Yeah.
ArtIsArt
8 years ago
From inside the ship, we're fine.
BrokenGlass
8 years ago
How close are we to managing it? I mean money aside.
ArtIsArt
8 years ago
In theory? We can do it. In practice, we can't do it fast enough.
