How do you create gravity in space?

Answer 1

In one way a trick question.

Gravity 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.

1) You could convert energy into mass.

2) You could functionally increase the mass by rapid acceleration (as physical objects approach the velocity of light, their mass increases dramatically).

3) You could use a mechanical device (such as a spinning object) to create a virtual gravity (like centripetal force).

4) 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).

5) 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."

Answer 2

Anything with mass has gravity. Even in space you have gravity. The appearance of "floating" in space as when you see astronauts in the Space Station is due to the fact that they are traveling at the same speed as the space station as it orbits the Earth. Some refer to this as zero gravity but a better term is called micro gravity.
What I think you are asking,though, is how do you eliminate that effect of floating. Probably the best way to simulate the effects of gravity in space is to design your craft with a spinning hull allowing centrifugal force to hold you down to ceiling of your craft. Your prospective would be that you are walking on the floor.

Answer 3

Gravity isnt created, it is always there in everything. The more mass something has, the more gravity it has. To "gain" gravity in space you would just have to be standing on something with enough mass to keep you pulled to it.

So bassically, a spec of dust has gravity just not enough to notice.

Answer 4

You'd need an artificial gravity generator, which will only work in confined space i.e. in a spaceship or colony, and whose mechanics is beyond me.

Actually, there ARE gravity forces in space, or else Earth would fling away from the Sun and we'd have no Moon either. Oh, and don't forget the black holes... :)

Answer 5

I guess you mean artificial gravity in the "Hey! Look, I'm not floating anymore" kind of a scenario.

This kind of gravity can be produced by several means; the "easiest" way is by rotation.The spacecraft could rotate so that anything inside will be forced toward the outer wall by centrifugal force.

The Wikipedia entry for this describes this in great detail and is quite clear. Here it is: http://en.wikipedia.org/wiki/Artificial_gravity

Hope this helps.

Answer 6

You personally "create" gravity wherever you are. Gravity is "created" by the presence of mass, and since you have mass you're "creating" gravity.

Answer 7

WE cannot create gravity in space.

Answer 8

Lots of complicated answers for a simple question.

1- Either you design your spaceship like a ring and spin it to create artificial gravity or

2- You keep your engines on for a 1 G accelaration or

3- Pull one of those Startrek tricks

Answer 9

Accelerate your spacecraft by changing either its speed or direction. According to General Relativity, the effects of acceleration are indistinguishable from those of gravity.

Answer 10

No Earth ground, No gravity. You can get it only on Earth.
You are very lucky because I am so free in this time.
