Artificial Gravity Generator Now Possible?

The artificial gravity generator is probably the science-fictional pseudo-science device most disliked by physicists. Used as a plot device as early as 1930 by Olaf Stapleton, artificially-produced gravity fields make space flight a lot easier and more bearable for everyone. But it's impossible, right?

Recent work done by researchers supported by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Martin Tajmar (ARC Seibersdorf Research GmbH, Austria), Clovis de Matos (ESA-HQ, Paris) and colleagues have successfully produced and measured a very weak gravitomagnetic field.

They summarize their results as follows:

  • 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.

The results were presented at a one-day conference at ESA's European Space and Technology Research Centre (ESTEC), in the Netherlands, 21 March 2006.

"We ran more than 250 experiments, improved the facility over 3 years and discussed the validity of the results for 8 months before making this announcement. Now we are confident about the measurement," says Tajmar, who performed the experiments and hopes that other physicists will conduct their own versions of the experiment in order to verify the findings and rule out a facility induced effect.

This is a very intriguing development, if it can be duplicated by other researchers. Artificial gravity fields were almost immediately decried as fantasy, not science fiction. The other method of creating "artificial gravity" was first used in science fiction just a year after Stapleton; Jack Williamson wrote about the City of Space in 1931:

"The City of Space is in a cylinder," Captain Smith said. "Roughly five thousand feet in diameter... The cylinder whirls constantly, with such speed that the centrifugal force against the sides equals the force of gravity on the earth. The city is built around the inside of the cylinder...

If you think that this research might have merit, and are interested in other science-fictional devices that make use of gravitational field control, take a look at Frank Herbert's gravity web vest, Larry Niven's sleeping plates and Isaac Asimov's gravitic repulsion elevator. Readers might also want to explore a more recently suggested method of obtaining weak artificial gravity for space stations; see this article on non-conductive tethers. Read more about the ESA experiments; nice paper (pdf) also online. Thanks to an alert reader for the tip on this story.
