    i was wondering if its possible to create an electromagnetic field large enough and powerful enough to collect and contain an atmosphere around on object in an otherwise atmosphere free environment?

    for example, say theres a floating city around jupiter, and jupiters gasses are being harvested to power a fusion reactor, so enormous amounts of energy can be created.. could perhaps the very metallic structure the colony is made out of be turned into a massive cathode to collect and contain a dense oxygen atmosphere while meanwhile repelling the denser hydrogen atmosphere of jupiter itself, essentially creating a bubble around the floating city which could allow people to be outdoors?

    just curious if this is even possible?

    Well, it's true oxygen is paramagnetic while hydrogen is diamagnetic. But it seems a stretch to me. Hydrogen is less than oxygen by the way.

    This electromagnetic field would also have to be so configured as to protect the city from the intense radiation field around Jupiter. Not sure how you are going to do that.

    this seems like something that would be impossible to do on lets say a martian colony simply because the massive amounts of energy it would take would be very hard to come by... has it even been confirmed that mars has a liquid core?.. seems geothermal energy could be hard to come by and solar would have to be used for generating power on mars.. but something like jupiter where youre literally floating on a sea of fuel, such massive amounts of energy could be more feasible.. anyway, its just an idea.. downside is that if the power ever went down, even momentarily, everyone outside in that atmosphere would be immediately killed

    Why do you think Mars would require a molten core (which, you are correct, it does not have) in order to harness geothermal energy? All you need is a temperature gradient.

    well, thats true, ive also though of the possibility of using extreme cold in certain parts of this planet, to harness the temperature differential of extreme cold temperatures above, moderate temperatures below to power a stirling engine which runs purely on temperature differences, but just how warm does mars get underneath?.. a planet its size is plenty big enough to generate a molten core on its own if our moon and mercury can have one,

    but if it truly does have a completely solid core (i hear theories that it could still have a liquid core), why is the core on mars solid, and just how much underground heat is generated, and how much power could you get off that?.. if youre building a colony within a cave you wouldnt need anything special to contain an atmosphere, the outside temperature is suitable for humans, which means underground temperature should be even warmer, youd really only need electricity for CO2 scrubbing and hydroponics i guess, but if theres enough vegetation you wouldnt even need the scrubbers, so yeah, its a possibility

    the real question is though is how will long term exposure to that low of gravity effect a person?, will their bones and muscles only lose density which could be re-gained through rehabilitation when coming back to earth or will something more serious happen? im also curious as to what the lowest pressure a human can be adapted to withstand?.. i know divers can become adapted to extremely high pressures underwater and have to be eased back into a lower pressure environment, but can a person be adapted to an even lower pressure environment?

    so.. what do you think the best candidates for colonization are?.. i just read another article that pointed out something i actually realized before but forgot about.. mars is covered in iron-oxide which, as i stated before i used electrolysis to de-oxidize metal, converting iron oxide back into iron... so something mars has going for it is all that soil equates to huge amounts of iron needed for industry, and oxygen

    also read that the lack of a magnetosphere can be countered with a thicker atmosphere, an atmosphere that can block out solar radiation like venus.. venus has almost no magnetosphere but in the many of millions of years its existed, its atmosphere remains, of course, it has far more gravity than mars does, but the fact that titan has such a dense atmosphere is proof that mars should have enough gravity to provide an atmosphere atleast as thick as ours, likely thicker, and we could probably adapt to the 1.5x atmospheric pressure present on titan... im sure there are certain chemicals that would be ideal to release into the martian atmosphere that would be particularly well suited for countering the radiation and solar winds while protecting the atmosphere we breath?.. also, due to the lower gravity on mars

    so do you still believe mars is the best candidate for a colony?.. and would you agree that the best way to do this would be inside a cave system?
