Is it theoretically possible for space ships to have an artificial gravity like they do in Star Trek?

I really wouldn't know that :idea:

I've read that gravity is theoretically produced by the interactions of elementary particles called gravitons, so I suppose if you can create a field within the deck plating, due to some kind of graviton generator, then I suppose it may be possible.

Our current understanding of gravity indicates that there is no way to artificially create a gravity field, and that gravitons do not actually exist, so no.  Gravity is formed by a large mass bending space-time, and as such is not a form of energy in the traditional sense as was once thought.

on a starship? use Centrifugal (spell check) force. :logical:

on a large space station you can take an object the same mass as mars, compress it into a micro black hole and use that. :cool:

cynthithical = "Centrifugal"

That may be the current understanding of gravity, but as of yet no theory full explains how it works.

The bending of space-time may, or may not be correct, as almost everything else in quantum physics seems to be basically the interaction of elemental particles.

I may be wrong here, but wouldn't a focussed gravitational field, made by the object you describe, actually have an inherently bad effect on the station, and the people stationed there?

just like global warming, we'll wait until it's too late. :logical:

Im not sure what you mean there, but i would say that even on a large station, rotation would be a much better option to generate gravity.

General relativity explains gravity with astonishingly accuracy.

In general relativity gravity is explained through space and time bending due to a object with a lot of mass.

So gravity is nothing more then the tedency of a object to fall to the center of the massive object. If the ground wouldnt hold us in our place, we in essence would all fall to the center of the earth.

The higher the mass of the object the higher the gravitational pull. So you would fall faster to the center of the object if the ground wouldn't hold you in place. Like on Jupiter. (immagine gravity being a slope of a slide or something. The higher the gravity/slope the faster you will fall)

Several conditions due to gravitiy have been predicted by general relativity and experimentally confirmed.

Like slowing of time due to gravity/space-time bending and einstein lenses.

So the problem isn't so much as to understanding gravity since we got some succesfull theories explaining it, but unifying gravity with the other 3 fundamental forces. Thats biggest issue at the moment.

Gravitons have been mentioned in quantum physics as a solution but when calculated often gives outcomes in infinity which doesnt make much sense.

So quantum physics is a VERY succesfull theorie in the very small region (atoms and fundamental particles) but doesnt make much sense at all when ranging in the very large. Planets, galaxies. Likewise general relativity doesn't work in atomic and sub-atomic scale.

Heh, i been working on the Gravity question for years since 90's.All what you see from science today is nothing more then description of the gravity effects and NOT the actual cause explanation.I have some idea about what the cause is and so far found nothing that would proved me wrong.I tried to actually find some real scientist to examen my theories but none were interested,heh shows how much humans love to stay on this  screwed planet in the stone age.
I wont say here what its all about just that stealth bombers might use this already to make the weight of the jet lighter as a roomer goes,cause this can be used both ways,to make a ship lighter or to increase mass at specific areas making not even grav dec plates but even warp engines possible... in theory of course.

General relativity may explain the effect of gravity, but it does not explain gravity itself: why mass bends spacetime?

We have no answer for that.

Gravity is related to the mass of an object. When you jump off the Earth you actually pull the Earth towards you as it is pulling you towards it - Earth; however, pulls much harder than you and so nullifies (reduces to negligably zero) your attraction upon it.
In Sci-Fi theiry, it is indeed the density of the anhiliation reactants of the warp core that provide the plasma stream with a colloidal gravity well which draws the objects to the bulkhead floors.
It's sci-fi! Pretty boring - or ridiculously stupid - if they didn't have gravity on the ships!

Spacetime? lol you dont even know what space time is!
Gravity is the cause of the objects mass,make no mistake about it.
SciFi explanations dont do a thing for me.
If you really want to understand what the gravity is,you need to forget 99% of what current science say about it.
