How do you create gravity in space?

In one way a trick question.\n\nGravity is the bending of the space-time continuum due to the presence of mass.  To create "gravity" you would have to create or accumulate mass.\n\n1)  You could convert energy into mass.\n\n2)  You could functionally increase the mass by rapid acceleration (as physical objects approach the velocity of light, their mass increases dramatically).\n\n3)  You could use a mechanical device (such as a spinning object) to create a virtual gravity (like centripetal force).\n\n4)  You could move closer to a massive object and be influenced by the gravity well of that object (satellite, planet, star or even black hole).\n\n5)  You could build a device based upon currently unknown technology that would bend space without any of the above.  This is the typical method used in "scifi stories."

Einstein explained gravity as a warp in the time-space continuum.  The best explanation I've ever seen was at a museum.  It's hard to explain with words, but imagine a square piece of fabric stretched taut on all 4 edges.  Now, place a weight (a ball, say, to represent a planet) in the center of that fabric.  It causes the fabric to stretch, and distort.  And any small items (marbles, say) that get in the area near the ball will roll toward the ball.

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.

1.  Hurl it spinning into space.  The vehicle will spin around its center of gravity, and its center of gravity will travel in a straight line.\n\n2.  Balance it on a see-saw three ways: upright, on its side, and on one end.  Each balance will define a middle plane that cuts through the vehicle.  The intersection of the three planes is the center of gravity.

I suggest you build an anti-gravity lifter device that is able to float in the air without anything supporting it.\n\nhttp://www.amazing1.com/grav.htm

Gravity is a force which keeps you stay in groud. For instance if you drop a pencil it falls to earth, if you through a ball to sky the gravity slows the upward thrust give by you to the ball & then pull it back to ground. Like this you can gine "n" no. of examples

In order to combat gravity, we would need to be able to understand what it is. At the moment, we don't. If we did, it still would be a tall order to mess with the field of a whole planet. Assuming we could "stabilize" gravity at the quantum level, whatever device we invented to do this would undoubtedly require huge amounts of energy.\n\nA much easier method would be to install a system of shock absorbers and hydraulics underneath the floor. Controlled by a computer, these could make up for some weakenings in the field and simulate to the human feet an equal field. This wouldn't actually solve the problem, just treat the syptoms. The air pressure of the cabin could also be increased to press our feet down on the ground more, but if we mess with this too much, we will implode. Also, there is the idea of placing a large verticaly aligned doughnut-shaped cabin to produce "gravity" in the form of centrifugal force, but this would be extremely impractical and require a lot of digging. I hope this helps, because until we have Artificial Gravity, there isn't really a lot that can be done. Cool question, though.

Gravity shapes objects.  If an objects mass is over a certain threshold then gravity will be strong enough to overcome molecular forces to "mold" an object.  Most asteriods have masses that are too low for this however planets and most moons are massive enough.  \n\nWhy a sphere?  This is due to the inverse radial dependance of the gravitational force.  In order words at a given distance from the center of mass distribution the force of gravity is the same.  This type of shape is a sphere.

gravity is an inverse square law type graph , you can plot it at y=1/x^2\ntry this site http://hyperphysics.phy-astr.gsu.edu/hbase/forces/isq.html\n\nanother graph is available here\nhttp://csep10.phys.utk.edu/astr162/lect/light/intensity.html

kfawl has the most accurate answer... that although we can realistically simulate zero gravity, and the only real way to do that is to use the aforementioned Vomit Comit - I mean we can't realistically put someone at the center of the earth, and sure, if you put someone in an elevator and cut the cords, for some time, the person will experience weightlessness - not that they'll notice since they'll be thinking of their impending death.\n\nAnd you can even go in orbit and although it will feel like you're in a zero G environment, logically thinking - the earth is gigantc and you've not travelled very far from it - how can there suddenly be no gravity? Because the shuttle is actually falling, but travelling sideways so fast that it keeps "missing the earth". This also applies to sattelites or anything orbit. The only reason Earth doesn't fall into the sun is because it is rotating so fast, it "keeps missing the sun."\n\nAnd although its been said that it is impossible to really be in a zero g environment, I believe if you go out far enough, the pull of the planets or stars will be so negligable, that for all intents and purposes, you'll be in a zero-g environment,

all you have to do is multiply the kg by 10 ( or the 9.81 which is the gravity constant)\n\nso you would have about 855 N

I don't know what exactly is your question! If anti-gravity could be manipulated ever, i think if would be very useful for us, maybe even in interstellar travels.

Yes, anything with mass generates gravity.  Gravity will only effect things which have mass, so the fact that you are stuck down means you have mass, and thus gravity.

Gravity. Water doesn't seek its own level on the Space Station, it forms a ball-shaped blob.
