Wow.My first post in here.
I wanna know how artificial gravity
works on the ships and stuff.
I know its there for being practical
.....and budget reasons! (tiddi-boom)
But it kinda confuses me.
How does this work?
(The following is not mine)

ERROR: GRAVITY IN SPACE SHIPS AND OTHER PLANETS
This is a biggie. Even assuming that something like "artificial gravity" would have been invented, then how does it work? Does it use some kind of centrifugal force? Then why is it that when people leave a space ship to clamber about on its outside in a space suit that they suddenly find themselves in zero gravity conditions? Doesn't this "artificial gravity" extend beyond even a fracture of a distance beyond its hull?

Also, distant planets (even known ones such as Mars) would have people on it moving about as if it has Earth-like gravity. Ever watched those astronauts on the moon bounce around in the old footage? This is a budget talking: it would simply cost too much to actually imitate the real effects of gravity in space . . . but still!

Another interesting question is how it is that when space ships confront each other in outer space, both are always inevitably "the right side up"?

Anyone who knows me here knows that I'm writing a
sci fi story and Ive got a system:on large ships--DS9,
Enterprise--People have a mandatory ingredient found on
another world sprinkled on food and drink.The ingredient
goes threw a persons system,and a chemical reaction happens in the body.The ingredient connects with stomach
acids and mutates.The body craps it, its cleaned and used as
a magnet sorta thing under the floor. The mutated substance is demutated and put back in food to start over because whats left in the body is all gone eventually.One can adjust how much pull there is in a room by a switch, so they can be weightless if they want.
Seems logical...
oh well.
Back to the point:how does Art. Gravity work?
Because it probably doesn't like my theory does.

Everybody in the ship has a small iron rod in their uniforms there is a large magnet in the underside of the ship which pulls the people down.

That doesnt explain the guests that beam up from planets though. It would have to be some sort of magnetic fields yes, but I don't think guests that beam up are going to have iron rods in their clothes. Oh and what about when people are taking baths or showers or what not?

It would be easy for astronaughts today if they had big magnets in their boots , since the floor is already made of metal . To answer your question , artificial gravity works by the use of artificial gravity generators , witch generate Gravitons , a theoreticle partical that is responsible for gravity .

How does it create those?
Is my idea good?
I think with very little posts here,
that the "Ingredient" would be some
Gravitons or something.
Help me please, I'm writing sci-fi!

the deck plating has graviton generators under them.

don't ask for a real science explanation for this type of artificial gravity because it doesn't exist

Yes . Unfortunatly , we cannot create the technology . At least not yet . No , i dont think your idea is possible , but it is very creative .

I dont know how this would work on a ship. But how about collapse a mass to about half its size with the same mass. It would be denser and have a stonger gravitational pull.

Its really quite simple.
Everythign in the universe:

The galactic core, each and every sun, the planets, etc. each are powered by their own hamster in a wheel, in the cores of the planets and suns, and the center of the galaxies. So AG is created by a hamster in a wheel in the computer core of the ship.

gravity is an intrinsic property of mass not density. if you take an object and condense it, it will still have the same gravitational flux.

things of course get a lot crazier when you get into several multiples of a solar mass.

Well there are two possible ways to create artificial gravity the first deals with a little known attribute of gravity that einstein predicted called gravo magntism.

Basically Einstein found that revolving a mass would generate a gravititional force similar to the way spinning a charged sphere would generate a magnetic field.

So if you can rotate a small mass at relativitic velocities you could generate a gravity field, there are some scientists ( Dr. ning Wu being the leader in this research) that have written papers on duplicating this effect using ions accelerated in in loops of superconductive wires.

see :

http://arxiv.org/PS_cache/hep-th/pdf/0307/0307225.pdf

Along these lines another Physicist, Raymond Chiao has postulated that because of the unique electrical properties of superconductive materials the development of a gravitational-transducer may be feasible.

Chiao's theory maintains that the gravitational-mass of conduction-bound electrons create gravitational waves as they react to electromagnetic waves applied to the superconductor.

"Over the years a number of physicists have suggested that if a superconductor can block magnetic fields--giving rise to the famous Meissner effect, which is responsible for magnetic levitation over a superconductor--then it might block gravitomagnetic fields, too."

According to theory, the conversion rate between the electromagnetic waves and the resulting gravitational waves is quite high -- Chiao estimates that as much as 50% of the incoming electromagnetic energy is converted directly into gravitational waves, which are then reflected off the surface of the superconductor at a 90-degree angle to the vector of the original EM wave.

"Chiao and Berkeley electronics specialist Walter Fitelson plan to beam specially polarized microwaves onto one slab of superconductor and use a second slab to look for rebounding gravitational waves."

Problem is that once you generate a 1 G gravity field it effect should duplicate that of a nature field. Basically following the inverse square law where the field force dimishes at the rate of 1/R square.

Now according to einstein Gravity is nothing more than the curving or warping of space, so if you could warp space on demand there should be nothing to create a area of space where the warpage mimic a natural gravity field inside a ship but drop to zero outside the ship.. The amount of energy require to do this would be mind boggling...:)

Hey long time no debate buddy. Hows that borg ship doing now after my voyager flew through it. lol.

Let me clarify. If you take a massive object and condense it untill it is superdense you could have the gravitational force of an object the size of a moon that is more manageable an can be placed inside a really large craft. More like a generational ship or a permanent space station.

Or you could take superdense material and line it on the bottom of ships. There are a few positive and or negative results.

1. You couldn't turn it off or on it would always be present.
2. It would require no power from the ship.
3. Not only would you have outward forces to deal with like acceleration, friction and others. Engineers would have to consider what a constant downward force on the structure of the entire ship would have when combined with the other forces.
4. Considering number three...all ships would have to be flat. More like the Klingon vessles, because if a part of the ship were lower than another, the lower half may tend to put stress on the upper by pulling it downward and in. OR..vice versa.
5. Anything below the ship would be pulled toward the bottom of the ship as well.

our you could configure your ship in a ring large enough so that the gravitational attraction from the opposite end is negligible compared to the part u are standing on. or a cylinder or sphere where everyone stands on the outside.

well don't they have arti. grav plating all over the ship? and that would be like the conductor for the field they create, because it can be turned on and off.

Im sorry to inform you we dont even know what gravity is!
Scientists think gravity is created by subatomic particles...

And on the trek series ships emulate gravitiy on each deck, below floor.
