If mankind had evoled in a zero gravity environment, how different do you think we would look/be?

We would be much taller,have fewer wrinkles, and live longer due to less gravitational force afainst our bodies.

The air would rush away from the earth.  The average speed of an air molecule is about 1,000 miles per hour, so the initial speed of the air rusing away would be about 1,000 miles per hour.  If you were outdoors, you might be carried away with the air.\n\nAs the air pressure dropped, you would see fog everywhere and you might feel chilled because when air expands the temperature drops.\n\nWhen the air pressure was low enough, the fog would disappear because the fog droplets would boil away.\n\nThen, as the pressure dropped more, it would become excruciatingly painful as the gasses came out of (exsolved from) your blood.  Blood would bubble out of all of your body openings, ears, eyes, nose, mouth, others.  Your body would blow up like a balloon and your skin might burst.  This would all be unbelievably painful.\n\nThen you would loose consciousness from a lack of oxygen and die.\n\nAll of this would happen very quickly, maybe in a minute.  The space shuttle flies at an altitude of 100 miles because there is no air at that height.  Since the air is rushing away from the earth at 1,000 mph, all of the air would be gone within 10 minutes.

I think you pose a very insightful and valid question. I've wondered this same thing myself and dreamed about the day we can created a structure like the one you describe.\n\nHowever, to create a rotating torus large enough to mimic earth's gravity would be unfeasable with the enormous cost right now to build in space. Plus, the way the space station is built puts almost no stress on the station. If the station were rotating it would have to constantly withstand the forces of "gravity".

hehe that's funny.\n\nBut I would not want to be cryogenically frozen! :)

OK, say that your answer is true.\n\nThis changes nothing. We still get up, eat, sleep etc. What changes is our perceptions of things.\n\nAfter the initial shock, life will continue as before.\n\nThere are no implications for a different life in your question. Aliens or no aliens, nothing changes.

Well, I certainly wouldn't have to worry anymore about whether or not I turned the coffee maker off! Seriously, if the Earth stopped spinning on it's axis, there would be much larger factors at work & I'd be looking for the quickest way to get out of what was going to become an extremely unstable area of space! After all, assuming that I had a craft capable of long range travel, it might be left up to myself & whomever else might also be out on other missions to find a way to carry on the human race :)\n\nWhen I read the question the first thing I thought of was, "Pause.......BOOM!"

In an ideal world, that would be great.  Unfortunately, that kind of reality is probably thousands of years away.\n\nJust like in Star Trek, we probably won't see that until aliens land, and show us exactly how primitive and violent we really are.  As long as we think we are the only civilization in the universe, there is little likelihood for improvement.\n\nI believe society is moving that way, but again, that's going to take hundreds of generations for us to evolve further.\n\nAnd if the aliens land and give us a book, don't go with them, "It's a cookbook!"

This is conceivable, but only in a very low/no gravity environment.  Thanks for your thoughtful question.

leave yes, but not forever.  then i could come back & visit & see how much space debris & space trash is floating in our upper stratosphere.  then i could appreciate how untrash the new place looks.\n\n\nby the way, do U really have monkey feet?

It would probably sound something like this:\n\n"AAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH"\n\nsince we'd all just fly off the surface of the Earth and shoot into space.

The problem with your question is that assumes that there are only to possibilities; we're alone, or there are little green men walking around.  \n\nChances are that there is some form of life other than ours in the universe, but it more than likely will be much more different than just having different skin and being a different size.  Think about how weird all the animals at the bottom of the ocean.  Then think about how similar their need for water, oxygen, food, how similar their DNA is to ours.\n\nNow try to imagine life evolving on world rich in totally different elements, exposed to total different frequencies and concentrations of energy.  The thing about life on other planets isn't really whether or not it's out there, but whether or not we'd even be able to recognize it when we see it.  \n\nThat and the fact that it takes years just to move from one solar system to the next.  Just getting to another planet capable of supporting life would more than likely take decades, even centuries with any conceivable technology(though an alien lifespan could make that less significant).  Any alien capable of travelling that distance, whether by nature or technology, would once again likely be so different from us that we would never recognize one another as living beings.  So there you go, little green men, probably not, alone in the universe, who can say.

No. Even if the human race moves-on to distant planets, the universe will remain diverse and we will not look the same.  \nJust watch an episode of "Red Dwarf."

Well, that would depend on your point of view.  Since there was no universe in existence before time zero, you would have to be inside of the rapidly expanding newborn universe.  Therefore, inside, there would've been extreme heat and pressures.  My guess is that you wouldn't have noticed any sound as you were boiled away into your constituent atoms.  So, I'm thinking a silent and dark time (as your eyes would've also been boiled off, so there would've been nothing to see with).

No we wouldn't age any less relative to everyone else on Earth becase we're all in what's called the same "reference frame." Relative to other reference frames, our aging rate would be different, but at the velocities involved the difference would be negligible.

I hope so...\n\nI would like to imagine a future of space travel for the human race.\n\nBut I have no expereince in the field to offer suggestions.

I’m not sure about movie Apollo 3, but the only way to simulate a zero gravity is a free fall. The free fall can be generated by taking an airplane into a dive. And I’m not kidding. Obviously under these circumstances the experience of zero gravity will last for a few minutes only.\n\nThe simulation of work in space could be done by using buoyancy by submerging astronauts in a pool of water. For more information I would visit NASA site.

ja :)..all objects with mass experience gravitational forces; about it's effects I don't know many, but the varicous veins for example are due to gravity in a way:blood doesn't flow up easily and gets stuck in his way and those are formed; also astronautes experience space motion sickness, when they are out the earth ( headache , nausea and even vomiting..yucky)...that's because our vestibular system is govern by the motion of liquid ,and when there is no gravity it originates changes.\nif you mean: humans ¨excert¨ gravitational forces by your question..I would say due to our little mass compared to the earth it means nothing (..unless you are really really fat! :P)
