Is it possible to make gravity with a machine?
« on: 10/02/2009 13:00:37 »
Is there any machine called Gravity Field Generator?Does it generate Gravity ?  [;D] [:D] [;)]
There must be a way to produce artificial G force .......

It's called "Getting an enormous amount of mass into as small-a-space as possible". Probably low on portability, though.

These folks claim they have done it. It seems plausible, but I haven't snooped around enough to get a clear take on it.

Here's the relevant quote:

Quote from: The Link
# An acceleration field was found to be induced by applying angular accelerations to a superconductor. The field produced is directly proportional to the applied acceleration with a correlation factor higher than 0.96. All mean values are 3.3 times above the facility noise level.
# The gravitational field is emitted from the superconductor and follows the laws of field propagation and induction similar to those of electromagnetism as formulated in linearized general relativity.
# Gravitational peaks were observed when the superconductor passed its critical temperature while it was rotating. Their sign changed with the orientation of the angular velocity.
# For the first time, non-Newtonian gravitational and gravitomagnetic fields of measurable magnitude were observed in a laboratory environment.
# The existence of the gravitational Faraday law was shown.

Could it be 'frame dragging'?

I guess it could be frame dragging; but they didn't call it that. Google gets a few other hits; some mention frame dragging.

could it be nonsense?
Please disregard all previous signatures.

Frame dragging is a special case of more general effects named Gravitomagnetic field effects (and they have talked about these):
