We know that angular momentum comes in packets of h/2pi.
Consider a binary star system with two stars of equal masses on a
simple circular orbit around their centre of mass.
We can calculate the angular momentum being spewed out in gravitational
waves by the system. If we require this angular momentum to come in
packets of hbar, what can we infer about the quantisation of
gravitational waves -- or the masses of the binary star system?
I don't know enough GR to pull this through, but in a semi-Newtonian
approximation, it looks like the reduced mass of the system is
quantised by Planck's masses. That doesn't make sense and must be wrong
:-). Could people who know GR try this out and let me know?
Thanks!
