First Steps Toward Artificial Gravity - TechAmok
First Steps Toward Artificial Gravity - [technology] 04:21 PM EST - Mar,24 2006 - (1 comments) Have scientists been able to
artificially generate a gravitational field? Researchers at the
European Space
Agency believe so.
Their experiment involves a ring of superconducting material rotating up to 6
500 times a minute. Superconductors are special materials that lose all
electrical resistance at a certain temperature. Spinning superconductors produce
a weak magnetic field, the so-called London moment. The new experiment tests a
conjecture by Tajmar and de Matos that explains the difference between
high-precision mass measurements of Cooper-pairs (the current carriers in
superconductors) and their prediction via quantum theory. They have discovered
that this anomaly could be explained by the appearance of a gravitomagnetic
field in the spinning superconductor (This effect has been named the
Gravitomagnetic London Moment by analogy with its magnetic counterpart).
Small acceleration sensors placed at different locations close to the spinning
superconductor, which has to be accelerated for the effect to be noticeable,
recorded an acceleration field outside the superconductor that appears to be
produced by gravitomagnetism. "This experiment is the gravitational analogue of
Faraday's electromagnetic induction experiment in 1831.
It demonstrates that a superconductive gyroscope is capable of generating a
powerful gravitomagnetic field, and is therefore the gravitational counterpart
of the magnetic coil. Depending on further confirmation, this effect could form
the basis for a new technological domain, which would have numerous applications
in space and other high-tech sectors" says de Matos. Although just 100
millionths of the acceleration due to the Earth's gravitational field, the
measured field is a surprising one hundred million trillion times larger than
Einstein's General Relativity predicts. Initially, the researchers were
reluctant to believe their own results.
Yeah. I'm finding this very hard to believe. But it's the European Space Agency...If true, this would be pretty much the biggest breakthrough since Einstein. Even reputable scientists are often wrong. We should wait for the paper, and then the flurry of counter papers before starting to believe anything.

They're talking about Gs there right? If so it doesn't seem like that would attract much of anything. But like anything else they could probably fine tune it and advance the method and materials over the next 100 years and maybe one day be in the range close enough to 1G to be able to counter the muscle atrify effect of 0G. I take it when they say it's much much more powerful (ha!) then what Einstien predicted they must mean that he pridicted no additional gravitational force aside from the mass of the matter itself. Superconductors rock! | |
