Do gravitational waves exhibit wave-particle duality?
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
My understanding is that "gravitational waves" are mechanical waves, like water, not "quantum waves" like light.
This article seems to confuse what wave particle duality means:
just like water waves are waves that are made of particles, we fully expect that gravitational waves are made of particles, too.
When it comes to duality it's the particles that exhibit wave-like properties individually.
Wave/Particle duality of quantum objects (quanta) is a bit like bicycle/car duality when looking at motorcycles. Light isn't a wave or a particle, but it has properties of both. Motorcycles aren't pedal-powered bikes or cars, but have properties of both.
There are no particles, just quanta.
When it comes to duality it’s the particles that exhibit wave-like properties individually.
And waves exhibit particle behavior because waves are particles and particles are waves. Light comes in waves. But when we see light it doesn't mean we are seeing a single light photon.
Surely that would require gravity to be quantized.
