B Question about the nature of Gravitation

[Swapnil Das]

Hello.

Modern Physics explains Gravitation in two general ways:

• In accordance to the General Theory of Relativity, Gravitation is thought of as an effect of the curvature of space-time continuum. This results in the formation of the recently and famously detected Gravitational Waves.
• Quantum Field Theory explains Gravitation to be mediated by a hypothetical particle called the graviton.

So can we say that even Gravitation obeys wave particle duality? Please express your views.

Thanks!

No. Gravitation is like the electric force. An electron or photon obeys the wave-particle duality, but the electric force does not. Gravitons, if they exist, would obey the same duality, but gravitation would not.

Thanks for your valuable reply!

The wave-particle duality is a property of a wavefunction, not of a force. A graviton is a perturbation of a vacuum and has a certain wavefunction in the quantum formalism. Hence it will obey the wave-particle duality.

Btw, see chapter 2 of this paper,

by one of our PF-users, for a clear explanation of the duality.

Gravitons have not been detected, although if they were that would certainly upset a few apple carts.
