What are some curious theories on what this all is? Existence in the universe is mind blowing when I sit down and think of what we are really a part of. What are your own theories about what we call 'space' is? Like, what's going on from a bigger perspective? Or smaller?

I made up a story for school. Where the universe is a gaint being thats further then the 4th dimension and we live like microbes inside of it and only scens this being in a 3th dimensional way . But its on a scale so big we cant understand further than intended,just like microbes we just live our purpose but cant visualise the being where in. And black holes are like a chemo killing microbes or problems that harm the universe.

I know science doesn't care about our feelings, but tell me of any alternate theories other than everything freezing to death or being ripped to shreds that allows something, anything to keep on going and surviving.

Can we eventually develop the technology that allows us to "jump" to a new, younger or possibly truly unending universe with different laws of thermodynamics to carry ourselves on?

Hold me, /sagan/.

The fact that anything exists at all is pretty much the biggest - well, it's technically the only problem in science.
Yeah, some scientists say things like "nothingness is unstable" and that may well be true. But if we can't figure out how nothing can turn into something - and why it turned into quarks, atoms, stars, planets, galaxies instead of something entirely different - there's no way we can say what will eventually happen.

But whether we're made out vibrating strings or just condensed balls of energy the only thing you need to know is,

yeah, that would be way better.

I think ISS is situated so that they can ditch it if they want to stop paying for it though.
the ring station would probably stay up a lot longer.

but to be fair it is the most expensive object ever created by mankind and arguably one of our greatest acheivements.

Kind of a dumb question.

I guess personally I do actually believe there is a formal point of life in the grand scheme, but that's sci fi stuff. I didn't realize it came out so much, but I still stand by it.
There must be natural rules to alien life, universal forms, just like the formation of mountains. If evolution is dictated by the environment, similar environments should create similar life. We are more related to horses than we are to deer, but similar habitats, similar place in the food chain, and similar food sources created similar animals, at least morphologically.

We won't be having hamburgers in space.

Or milk or eggs, for that matter. For every cow slaughtered for food there must be an incredible amount of food grown to sustain the cow. In space stations this may not be feasible due to limited space and resources. We'd be better off focusing energy on hydroponics and a vegan diet would probably be necessary in a long term colony or space station.

Why would you want to destroy a planet?
In the movie Dark Star, they blew up entire worlds because "instable planets" could threaten the future colonization of other planets.
Is it viable to blow up a planet to mine it as with asteroids? What other use could it have? Elimination of gravitatory perturbances in an Interplanetary Transport Network?
Blowing it up wouldn't send tons of material into chaotic orbits?

Sorry for too many questions. I just read about asteroid mining and thought about why not Jupiter with all that hydrogen?

That would take a lot of energy, a ton of which would be released as heat. I think the debris would be too hot to be useful or mine-able for a LONG time.

I would be awesome if that dishwasher-sized satellite was the last tiny bit of mass needed to collapse Jupiter's core and start the fusion reaction.

I recently realised that I'm completely fascinated with the early space programmes / the early space technology / the early space race. I would say from the very beginning until the end of the 80's.

So as far as I know, there are two theories on the ultimate fate of the Universe.

One is that the Universe will experience heat death and that chemical reactions and everything reliant upon them will cease to be.

The other is that the universe will tear itself a new one, collapse in on itself and reset.

Either way, humanity, every other sapient species in the universe and everything we've ever known and accomplished will amount to nothing.

On a scale from "Stubbed your toe" to "Visigoths sacking Rome", how does that make you feel?

For me, I'd say that it triggers a "Read Ecclesiastes and contemplated petty arson" kind of feeling.

Personally, I already felt like whatever humans did would amount to nothing in the grand scheme of things anyway. I have absolutely no faith that Humanity won't completely blow each other up in the future and eventually when Earth dies entirely nothing we didw would matter anyway. I don't believe we'll ever colonize another planet or anything, I think we're too stupid as a species for anything that cool.

It's in orbit!
I would be lying, if i said i wasn't excited most about the bright spots.
Seems like it's a bit of a wait still, until we get clearer images, though.
It's pretty fucking cool nevertheless

"The most recent images received from the spacecraft, taken on March 1 show
Ceres as a crescent, mostly in shadow because the spacecraft's trajectory put it on a side of Ceres that faces away from the sun until mid-April. When Dawn emerges from Ceres' dark side, it will deliver ever-sharper images as it spirals to lower orbits around the planet."

I think you're defining the word "novel" too strictly. I'd consider any form of cryovolcanism to be novel because the evidence itself is relatively new and much of it is based on indirect observation.

We are not alone in the universe, just because we have not found life on other planets some people seem to doubt the possibility of alien life. I'm just here to tell you we have not even explored 1% of our galaxy for alien life. It's even probable that there are sentient species as advanced or more advanced than our own i this galaxy based upon the age of it. The main ingredients for life (amino acids) are not that uncommon from what we know. How do we know for sure those are not alien spacecraft we see on occasion in our skies? What's your theory on how advanced alien life is?

there's already a space alien thread on page 0, so i'm not gonna bump, but until we find fossils or microbes or something somewhere that isn't Earth, or until somebody talks to us, it isn't 'probable', it's possible. We've literally got a sample size of 1 to look at right now. Kind of impossible to determine probability based on the one single rock in a galaxy with billions and billions of rocks that sprouted life.
It's fun to think about, and I'm in the camp that believes there's life out there, but we just can't possibly know it based how very, very little we can observe things not on Earth.

Furthermore, 'sentient' life seems like an unbelievably rare occurrence. It's only happened once here. Multicellular life in itself is probably excessively rare if life even exists elsewhere to begin with, animal life even moreso. Rarer still would be a self-aware species. Yet rarer would be self-aware species capable of technological civilization. It's fairly safe to assume quite a few civilizations would end themselves before reaching the stars, and who knows; it might simply be too much time and energy to cross interstellar space for such a species to leave its home planet.

UFOs being filled with little green men is silly, though. Remember all those UFO sightings in the American Southwest during the Cold War? How people thought that they had flying saucers holed up in Area 51, and then a bunch of files were declassified and it turned out the Air Force was testing SR71s and shit out there?
If space aliens have the technology to efficiently get around and build a galactic civilization, then we're like, an ant colony in New York City to them. So advanced compared to us that we could not possibly comprehend them.

I dunno, man. Imagine what people might be like if we manage to maintain a technological civilization for a a thousand, a hundred thousand, one million, five hundred million, even billions of years.

Who knows, though, maybe we're lucky number one. The first civilization to emerge in the galaxy. It's not unfeasible, really. Shit, we might even be the first planet to have life. Or maybe life came to Earth from somewhere else. It's hard to say.

Imagine no restrictions of the creation of it. You have an unlimited supply of dense matter to throw into a big old sphere. Say, I dunno...Iron. Unlimited iron. You can just throw that shit by the teraton into one even pile.

I mean, you could create a black hole eventually, right? It would get really fucking hot at first...molten...then maybe some sort of weird plasma? But we keep throwing on the mass. Using special Future Magic to keep shit contained. You get a black hole at some point, right?
