Gravitational waves are ripples in space-time and has never yet been detected.?

Question

It might seem a bit stupid but can these waves propagate as particles as well according to the wave particle duality of light or does it just hold for light only?

Answer 1

The LIGO experiment is looking for gravitational waves using a very large interferometer.  It has not yet detected anything.

I suspect that we'll have to wait for the space based version to get a real detection.  Unless we get lucky enough to have a nearby energetic event - like a supernova.

Answer 2

Light (and the electromagnetic field) are characterized as particles/waves that travel in space. Gravity waves are ripples in space itself. String theory holds that a gravity particle (the gravitron) must exist, but so far, neither it or gravity waves have been observed. Probably because gravity is such a weak force compared to the other three.

Answer 3

The wave-particle duality applies to *everything* as far as we know: light, electrons, neutrinos, atoms, etc. The theoretical particles for gravitational waves are called gravitons. They have not been detected.

Answer 4

There have been a number detectors constructed like Lidar and a resonating cylinder. So far no one has crowed that gravity wave has been detected. Here on Earth we are  bathed in it from the earth itself and to detect it may be difficult to ID with the current technology. May be if the detectors were in deep space away from influence of large objects it may be easier to detect gravity waves.

Answer 5

The entire electromagnetic spectrum can propagate as waves and particles, this includes x-rays, microwaves, radio waves etc. as far as i know gravity cannot
