Question

THE GRAVITY is the waves or not can we control it or not??????

Answer 1

Gravity, and a definition of it, has confounded science for hundreds of years. Isaac Newton managed to create rules that governed its effects and they are still good enough to be used by NASA. Einstein refined these rules to account for anomalies in the orbits of planets and he proposed that a massive body warped the space around it, this has been verified. However, we still have not determined how the effects of of gravity are propagated.

Answer 2

i haven't read this anywhere but i  just think that gravitational waves must not  be existing for the reason that for anything to be a wave,a disturbance is required,wave doesn't depend upon the mass of the source or the target unlike the gravitational attraction.

though its true that gravity has gravitational lines which become weaker as the distance decreases.

ya, i think we can control it bcoz i have read that astronauts are given training by putting them into 0 gravity chambers.so if we can maintain 0 gravity situation,then why not control it !

. I don't know the technique

Answer 3

Gravitational waves (like electromagnetic waves) occur when the source of the gravitational field is rapidly changing.  Because gravity is so weak, though, and because large masses don't tend to move too quickly, we've never actually found them.  Experiments are underway to detect gravitational waves from supernovae.  It is unlikely that we would ever harness gravitational waves.  But who knows?

Answer 4

Gravity is the weakest of the four fundamental forces.  EM force is about 10^35 times stronger than gravity for example.  As Brian Greene pointed out in his "Elegant Universe" the strength of the EM force over the gravity force is illustrated when a person falls from a four story building and hits the cement below....splat.  If gravity were stronger than EM, the body would go right on through that cement.

I am currently writing a scifi short story where the hero invents a way to modulate gravity.  The strictly fictional device is an alloy of rare metals that, together, create fluxuations in mass when hydraulically pinched and relaxed.  It's a sort of piezogravitational device wherein the pinching energy is momentarily converted to additional rest mass.

Why would we want a piezogravitational device?  Because, according to string theory, the inherent weakness of the graviton may be due to part of the graviton existing in a parallel universe outside our four dimensions.  In which case, we can send gravitational waves into that parallel universe and, perhaps, contact the "other side."  Which is why I call the story Contact II...where Contact is the Carl Sagan story portrayed in the movies by Jodie Foster.

Answer 5

An object or particle spiralling into a Black hole loses energy through gravitational radiation. As it reaches its last stable orbit, it falls rapidly into the Black hole and emits a last gasp burst of gravitational waves. The total energy radiated during the slow inward spiral is equal to the binding energy of the last stable orbit: -

E(radiated) = μ - E(last orbit)

Where 'μ' is the rest mass of the object or particle. It may be shown that for a Schwarzschild hole this has a value of 0.0573V and for a Kerr hole 0.4235μ. The total energy of the last gasp burst is about 0.01μ(μ/M) if μ<<M.

Gravity waves travel at the speed of light. Thus, if the Black Hole gravity radiation source is 100 light years away from the Earth, it will take one hundred years before the gravity wave passes through 'us'. As the gravity way passes through a mass, it distorts it in two perpendicular directions to its direction of travel with cruciform type oscillations. Furthermore, the passing gravity wave imparts a very, very small amount of energy into the mass and because of this; it is very difficult for experimenters to detect the passage of such waves. It is hoped that the LIGO (Laser Interferometer Gravitational-Wave Observatory) gravity wave experiment, which has been running since 2002, will be able to detect gravity waves from exploding supernovae and coalescing binary Black Holes. Different gravity wave sources can deliver waves of a wide range of amplitudes with a frequency spectrum of 10^-7 Hz up to 10^11 Hz travelling at the speed of light. More intense gravitational waves can be expected from Coalescing Binary Neutron Stars.

However, controlling gravity waves seems unlikely because they deposit an absolutely miniscule amount of energy when they pass through matter.

Answer 6

I wouldn't lose sleep over this since gravitational waves have never been observed. They do seem to fall out of the mathematics of general relativity but that does not necessarily make them real, just an abstract mathematical construct that might possibly exist. A lot of time and money has been wasted on detectors that anyone with half a brain would know were not sensitive enough to detect these things since they are extremely weak if they even exist at all. But so called scientists, eager to scarf money from the public trough just as any self respecting DOD contractor, don't mind hedging data, etc to get their governmental welfare.  But, back to your question, why would we want to control them? What would we do with them? Since they are so weak, how big a generator would you need to build to create a large enough wave that you might actually be able to put to use doing something?
