How would Anti-grav and Artificial Gravity work?

The same way the transporter's Heisenberg compensators work: They work very well, thank you.

Isn't gravity negative potential energy? Well the opposing force to gravity would be some form of positive potential energy which would rather than pull stuff towards it, would instead push stuff away, if the same amount was produced as the local gravity field you could effectively produce conditions of zero gravity.

If one could produce positive potential energy in sufficient amounts you could use it to push people down onto the floors of an object in space (i.e. a spacecraft, space-station) and produce the effect of having 1g by pushing people down with that force rather than using gravity to PULL them down. After all if you're pushed down with a given force, or pulled down with a given force it ultimately feels the same.

GEAAAAAAAAAH!!! ZOMBIE THREAD!!!! RUN!!!!

Re: would Artificial Gravity work ?

like a centrifuge, just like Clarke's Discovery One or one of those gravitron rides at the amusement park.

2001 would work in even the darkest, loneliest corner of the cosmos.

What's more (and as a freebie answer to the three or four folks who asked it) the gravitational waves travel through space at the speed of light.

Impressive. You succeeded in resurrecting a thread that is OVER 2 years old.

I sometimes think of an interesting analogy in fluid dynamics. Compare a source/sink and a vortex. With the source/sink, the fluid flows radially, while the vortex has fluid flowing in the angular direction.

____

________

source. sink if arrows are reversed ---- vortex. can rotate clockwise or anticlockwise.


One creates a pulling force, the other creates a pushing force. This effect can be seen if an object is place into a flow: Objects near a vortex are accelerated away from the vortex. Objects near a source/sink are accelerated towards the source or sink.

I've sometimes wondered if gravity could be interpreted this way: As a flow of some kind which objects react to in the same sort of way.

This wouldn't necessarily oppose existing theories, but if the analogy works, then it may offer some insight into what curved space-time actually is and why it curves the way it does.

I've never really explored the idea to see if it is consistent or not.
