can we live in space?

Answer 1

yeah, we are right now if you think about it

Answer 2

Not for very long. Where are the resources that support life? No air, no water, no soil for growing plants for food. All there is, is diffuse energy in the form of sunlight. This can be transformed into electricity by low efficiency solar panels. You can do a lot with electricity but you can't eat it, you can't drink it and you can't breathe it. Lack of gravity could be unhealthy and artificial shielding against cosmic and solar radiation would be needed

Best place in space for a colony is on Mars. Not much air there, but the Martian atmosphere can be turned into oxygen with simple 19th century chemistry. There is water, and it may be possible to get things growing in Martian soil in greenhouses with a bit of added organic matter and stuff brought from Earth. In addition the day is 24 hours and about 40 minutes long which would be suitable for plants. Sunlight is weaker but probably adequate specially for food plants bred for low light conditions. There is some gravity (not as strong as Earth but higher than on the Moon) and the Martian atmosphere, even though it is thin, provides some shielding against radiation. Martian temperature ranges are extreme but much less extreme than in space or on the Moon.

On the Moon - weak gravity, no atmosphere at all, very little or no water and a totally unsuitable day length. Radiation is a problem and temperatures range over 400 celcius degrees day to night which would be a problem for people trying to design air tight shelters.

Answer 3

Well if given time and if we develop the required technology, then Yes, there are many ideas about building orbital stations like a Stanford Torus or a O'Neil Cylinder (might be awhile before seeing anything of their size at the moment) but both would have gravity due to centripetal acceleration (aka it spins).
Even thou this bit is abit beyond your question, but there are also ideas for other planets too.

Read the source link provided as its more in-depth on the subject.

Answer 4

Hey, if the Russians, Chinese and Americans can all go up and stay at the international space station then yes, technically we could. Not everyone at the same time of course, in that station, it would be way too crowded (lol) but i guess if there were a lot of stations! Sure why not!

Answer 5

Is it Arthur C Clark who thinks you could survive the vaccuum of space for a few seconds by holding your breath?

My Colour Sargeant told me the other day that if an explosively formed projectile penetrated the armoured vehicle it would cause a vacuum that would rip off my arms and legs. So presumably the vacuum of space would do the same and Arthur C Clark is wrong.

Answer 6

Yes, but we're going to have to make our own air to do so (and it might be a good idea to also make some gravity and have a couple of metres of radiation shielding while we're at it unless you want to cower under the Earth's magnetic field like the people on the ISS do, oh and some hydroponics would be nice as well).

Answer 7

over time in space without artificial gravity, muscles and bone would deteriate due to the lack of gravity. But anything could be possible one day :)
living on other plantes however is a different ball game, you would ofcourse need a planet with near conditions to earths, theres none in our solar system. Mars however is withing the green band area which means that it could sustain life. But not suitable for us humans unfortunaely, temperatures on mars can reach - about 200 degrees. i think.

Answer 8

I'd like a bit of space

Answer 9

But we already live in space...

Answer 10

Ther is no air ,(oxygen,nitrogen or any)in space.So it would be hard for humans to survive.It is an hostile environment.Maybe in the future technology will be more advanced than now and we may be able to live there.
