would it be cool if there was no gravity but you could still breath?

NO!  If there was NO gravity then you wouldn't be able to do anything.  Everyone's hair would be all over the place.  Sports would be over forever.  Sex would be next to impossible.  This is just stupid.  \nBy the way, it's breathe (not breath).\n\nRev. Jank

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.

Wait...doesn't everyone in the world already breathe at the same time?  \n\nAre you trying to say that if some people weren't swimming under water or having a breath holding contest, we'd run out of air?  Wow-I thought I came up with some crazy stuff.\n\nI'm going with no on this one.

Depends on your momentum when you do so.\n\nIf you're utterly still and blow out air in space, you will move backwards.\n\nWell, your frozen corpse will...

Don't worry, this will never happen. The "gravity" of the earth is actually caused by attraction between two objects of significant mass.  Were the gravitational force of the earth to vanish, that would mean that the earth itself had vanished.  It would also mean that you would be in free-fall, expereincing what might appear to be weightlessness.  not that this would matter considering that you would be in the void of space and would be dead.

No, because you are moving with the Earth while you're in it's atmosphere.

Yes. The gravitational force is not that weak.\nNote also that the pressure difference is not sudden at all, higher and higher into the atmosphere, the pressure becomes lower as the weight of the particles above becomes less. As the pressure gets lower, the effect of gravity is also lower.\nWe do still lose some air particles into space, but not a significant quantity.

at first the answer seemed obvious, of course you would.  But the more you think about it, the more it doesn't seem so obvious.\n\nI have to go with the answers that say you would feel the pull of gravity from all directions and therefore feel weightless.

assuming that you could do it and you didnt die and all that, you would go through to the other side.  if you include air resistance, you wouldnt make it to the other side, you would accelarate until you reached the center of the earth or until you reached terminal velocity, then you would start slowing down after you passed the center.  you would then start falling back toward the center in the opposite direction, passing it again, you would oscillate back and forth like this, losing some distance from center on each pass, eventually you would come to rest at the center

Hi Steve, I had the same idea when I was about 8 years old and I can tell you from experience - it doesn't work!!  The increased pressure from the water pushing on your body makes it impossible to inhale from the hose.  Your lungs are designed to work at 1 atmosphere of pressure and they just are not efficient enough to suck in air like that while underwater.  It could also be very dangerous for someone who is not properly trained to breath off any air supply while submerged, if you were to hold your breath and ascend, your lungs would burst from the increased volume of air which would cause an injury called an Embolism - not a good thing!

OK... let's get graphic.\nFirst off..... you'd die! No way around that!\nWhat would kill you first is the question.\nSpace is incredibly cold, so instant exposure to space would freeze almost all liquid in your body solid.\nSpace is also a HUGE vaccum, so all the air would be sucked out of you either while you're freezing solid, of during your freezing process.... either way, you'd suffocate if you didn't freeze by some miracle.\nSpace has absolutely no compromising pressure like the inside of our atmospere. Our bodies are used to a certain atmosperic pressure. Without it (I.E in space) if you didn't freeze or suffocate, eventually the lack of pressure would collapse our fragile bodies.\nThe possibilities for death are indeed endless.

Gravity is the only thing keeping the air that we breath here for us to breath.

Things would weigh less than on earth\n\nst

Well, the air is so low you definitely need an oxygen tank to aid in breathing. As far as elimination....it DEPENDS??? ha ha.

how are you supposed to swim on the moon? what about snowboard? i think it is pretty hard to do sports without much gravity.
98562
Yes!  Gravity has nothing to do with air, or the lack there of.  People tend to accociate vacuums with the absense of gravity because of the vacuum of space.  However, gravity is what keeps the moon orbiting the Earth and the Earth orbiting the sun, even though there is no air in space.
