in a cartoon(dragon ball z) they made a room that creates more gravity then earths?

Question

is that possible in reality?

Answer 1

There are several ways to produce this sort of effect. In order of most probable to most ludicrous:

1) Centrifuge. It's not really gravity, per se, but being pressed into the wall by angular acceleration while the centrifuge spins. To properly simulate gravity, the centrifuge should be in a microgravity environment, otherwise you're going to have a tangential acceleration due to the Earth's own gravity. This is really the only practical way you could do such a thing without having to rely on reality-defying sci-fantasy magic.

2) Gathering enough mass in one place to produce an acceleration due to gravity several times greater than that of Earth's. The problem with this is you need some fantastically dense matter to pull this off in any reasonable space. Say neutron star matter, since compressed degenerate matter takes up quite a bit less room than the fluffy non-compressed matter that makes up the Earth. The problem with this is that such a heavy mass will exert multiple Earth-gravities of pull on everything else, including the Earth. As a result, our hypothetical room will immediately begin sinking, and go right on sinking until it reaches the center of the Earth. The tidal interactions would also result in the extinction of all life on Earth.

3) All molecules and atoms are effected by electromagnetism in some way. This is the principle behind MRIs. Theoretically with some really freaky, almost arbitrary ability to manipulate electomagnetic forces, you could create an acceleration feeling very much like that of gravity, and you'd need many times less charge carriers than you would mass, since electromagnetism is a much, much stronger force than gravity is. Of course, this sort of fine-control over electromagnetism will probably require a fair bit of handwaving, and possibly some unobtanium to pull off.

Answer 2

Well, if you wish to form a gravitational field that has greater intensity that what we experience on the surface of earth you would have to consider what is said in the physics trilogy concerning the formation of a field of gravity. The trilogy is: E = mc2, m = E/c2, and c2 = E/m. The last is that for a field of gravity. It is a mass to energy relationship. The reason it exists may be found at http://360.yahoo.com/noddarc "The Problem and Repair of Relativity" and "A Gravitational Experiment You Can Help With" both being short and easy to read.

What you shall find is that the force of gravity is a particular form of energy and is able to be increased and decreased within a mass. In order to form a field that would be greater than that of earth, it would require a particular mass being greatly compressed. Notice the equation c2 = E/m. By increasing the energy to mass ratio the "c2" value increases. The reason a small mass is able to be more intense than that of earth's, is that a person is able to move closer to the center of a small mass having a gravitational field increased, whereas in relation to our planet we are 4,000 miles away form its center, where the force is most intensive. To understand the "why" of this one of the above writings should be read.

Answer 3

Objects that have more mass have stronger gravity so in order to have a room with stronger gravity it must be on something with more mass than earth.
There is another way, though. The effect of gravity can be synthesised by spinning the room really quickly. Think of the fairground ride that is circular. People are strapped to the inside of the circular frame and it is spun quickly. The people on the ride feel that they are heavier, as if there is stronger gravity.

Answer 4

No . The Only way you could produce more tha 1 g on earth is in a centrifuge. Go back to your comics.

Answer 5

you should be inside a chamber rotating at high speed, that would push you against the walls.

Answer 6

in the future it might be possible

Answer 7

I don't think so... it is impossible
