Scientists
might have observed the gravitational waves or the curves in space-time. But we
still have a limited knowledge about how gravity affects the universe. André
Füzfa, a mathematician at the University of Namur in Belgium has proposed a
method that would allow humans to control gravity.
Füzfa says "Studying gravity is a contemplative activity. Generating artificial gravitational fields, that could be switched on or off at will, is a question captured or left to science-fiction."
Füzfa's
proposed device has not yet proved experimentally, so we should not get so excited
about it, but he has completed the calculations related to the proposed device.
His device is based on huge superconducting electromagnets.
In fact, his
assertion is quite close to reality as it is based on the equivalence
principle, which is at the very heart of Einstein’s general relativity, and
states that all types of energy produce and undergo gravitation in the same
way. So it indicates that electromagnetic fields can curve the space-time as a
planet or a sun could. But we can’t observe these minute curves here on
Earth. Füzfa proposed that by assembling
huge superconducting electromagnets, we would be able to establish a feeble
gravitational field, and this would be observed by using highly sensitive interferometers.
These
interferometers would superimpose the gravitational fields on top of each other
so that the physicists could get details about them. It would be very difficult
to make an IRL device of this kind, with only mathematical proofs to continue.
If we are be able to control gravity just like the way we do with the other
three fundamental forces - electromagnetic, and strong and weak nuclear forces
– it might just be a big enough prize to take a gamble on.
It would
ultimately take gravitation into a new experimental and industrial era.
