Why do we not have these yet sci? (see pic)
How expensive to do is this really? And how much time would it take?
Does not every sane mind on this planet see the obvious value of creating such platforms for mans expansion into space?

Make space pay for itself a thousand times over. Chase did a study in the 1970's determining the economic impact of the Apollo program, and they released that for every dollar spent, $14 was returned in terms of how many extra people were inspired to become scientists, engineers, optimism of people investing in ventures that they usually probably wouldn't of, etc.

Just to comment on your idea of asteroid mining... Yes, a small asteroid will contain large amounts of valuable materials(metals and other chemicals), but then so dose virtually every part of earth. The problem is in mining and refining them. Unlike the earth an asteroid has been pretty much just sitting in space collecting any debris that happens to come along. So it's structure is generally homogeneous. Consider gold as an example, while there maybe many thousands of tones of gold in a small asteroid it will be so sparsely spread that mining it would cost more then the gold would be worth by several orders of magnitude. We have the same problem on earth actually. There are areas which are "High" in over all gold construction , but it's relative construction is too low to support even the most ambitious and modern mining methods. Now this may change in the future, but there are up (thermodynamic) limits to efficient mining. It's quite possible that mining an asteroid may never prove profitable because of it.

An asteroid full of oil would most definitely be worth it. It would likely be able to fuel the nation ten times over.

You're obviously the troll if you don't believe a rock surface with such mass is capable of carrying an abundant amount of oil and fuel. You learn to geology, dumass.

[Anonymous No.3585155]

>>3585145
Not sure if trolling but let me just say they are called FOSSIL fuels for a reason. Now we don't get fossils without living things and guess what you can't find on asteroids floating in space.

[Anonymous No.3585163]

>>3585155
Wow, now I know you're retarded. They are called only referred to as fossil fuels because of their age. Oil is extremely old and to think it came from anything living as of today is one of the most retarded ideas I have ever heard. Asteroids are just around the correct age to carry oil though. And even if not, then there are still asteroids nearby that are broken off from the earth during the prehistoric period.

If there was an asteroid in space that even gave signs of having oil, we'd be all over space in a matter of months.

Then we'd die as we tried unsuccessfully to get the oil back to earth without it burning up and turning into a goopy rain of fire.

You would think so but as that other idiot has proven, most people don't believe its even possible for oil to exist outside of earth. Then why isn't oil more expensive then say diamonds or gold? That would make oil one of the most rare substances in the entire universe, correct? Then answer my question

[Anonymous No.3585187]

>>3585163
>Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms.

Too have fossil fuel you need to have living things, Flora and Fauna included

[Anonymous No.3585189]

>>3585187
Yes which is why I mentioned prehistoric asteroids, which are also the most abundunt in our solar system and easily more likely to carry fuel. That type of oil can be found in prehistoric asteroids. The type of oil I am speaking of is not a formed under the fossil hypothesis. And is more prone to being found in places other than earth. Fossil fuels aren't just dead animals

[Anonymous No.3585209]

>>3585182
>oil one of the most rare substances in the entire universe
I never thought of it that way. You're still an idiot though.

Also diamonds aren't expensive. They're made of carbon and are super common. It's just when they're cut all pretty they get expensive for no real reason. Humans like shiny objects I guess.

As far as we know you either need life to create or to artificially make oil.

Furthermore, if there is life, intelligent space faring life, and they need oil to fuel their space travel or planet, and it were possible to get oil from asteroids, they've probably already tapped them.

[Anonymous No.3585219]

>>3585209
So now you're saying there is no such thing as otherworldly life capable of producing oil that would break off of their home planet in the form of an asteroid? Seriously, your entire argument is breaking up.

And don't call me a god damn idiot. You asshole.

[Anonymous No.3585234]

>>3584750
Many times over more expensive than the whole industrial output of the world. We'll have to wait for the economy to grow. At our current industrial capacity constructing this would take centuries even if all the nations co-operated. And we wouldn't be producing anything else, a bit like those crazy ancient construction projects that bancrupted nations.

[Anonymous No.3585236]

>>3585189
... There are almost no asteroids that were formed by being broken off of the Earth.
The majority of asteroids in the solar system were formed at the same time as the sun.

There are abiogenic sources for long chain hydrocarbons, but they require massive pressure that asteroids lack.

Actually, that massive pressure is why many gas giants are composed of a good chunk of methane.

impossible and severely improbable can be treated the same for the purposes of arguing something that has to be practical. if we found oil in an asteroid, we would be shitting ourselves over possible evidence of extra terrestrial life.

[Anonymous No.3585258]

We would have to get the resources to build that from other planets and asteroids. It just takes too many resources.

We will have to wait until we have terraformed a few planets to start building artificial ring worlds like that. While we terraform we can get by with smaller centrifugal space-stations...

ok first off, why so butthurt? there is more than one person on this forum, and i never insulted you. dont assume one comment came from a person another comment came from.
Secondly, i just corrected you when you were misinformed, and did you a favor. its improbable that another planet harboring life was struck, dislodging but not consuming oil in the resulting explosion and then later being found by another planets inhabitants. the significance of such a discovery would be more important than the resources obtained.
thirdly, for the record im under-educated, not over, and i had a similar childhood. i think most people have had bad parents, so dont take it so personally.

This only looks about as complicated as building a dyson swarm right now.
