comment At which point are gravitational waves generated when two black holes merge?
The Hulse-Taylor binary pulsar is a great demonstration of the earlier, weaker emission en.wikipedia.org/wiki/PSR_B1913%2B16

comment Has a stellar blackhole more mass than previously?
Just a small correction: The inward force compressing the matter is just gravity. The expulsion of matter outwards is a consequence of tapping into the gravitational potential energy.

comment Metal-rich star formation
Isn't the process of star formation sufficiently complex that it's possible that a single value for a maximum metallicity is impossible to compute?

comment Why is Heisenberg uncertainty principle not valid in waves in string?
Is $\mu$ as you've defined it really the mean value of $f(x)$? I would say that it's the mean value of $x$, if $f(x)$ is interpreted as a probability amplitude.

comment Why do some types of waves disperse?
And before dives in with the full mathematical derivation of the dispersion relation, I think I'd add that a truly helpful answer to this question would provide some physical intuition for why the mathematics gives the result that it does.
