comment Why are laser beams not affected by gravitational waves in Michelson interferometer?
This question is similar to: Is LIGO flawed by the identical expansion of laser wavelength and arms in presence of a gravitational wave?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem.

comment What is the relationship between core temperature and surface temperature in main-sequence stars?
Can you clarify what you want. An understanding of why the relationship exists or just a table of values? (There is no simple analytic relationship)

comment Isn't the induced electric field vector always tangent to the loop?
Since the law is true for any loop then how could your proposal be correct?

comment Why Cepheids have Period Luminosity relation?
@Polaris5744 I got from your question that you understood the kappa mechanism but wanted to know why there was a period-luminosity relationship.

comment Why are heavier nuclei unstable?
That's why I wrote "highly neutron rich nuclei will be unstable".

comment Does a football field size asteroid really fall past the moon once a week?
It's the cross-sectional area that matters not the volume. I.E. probability of getting within $r$ goes as $r^2$. The lifetime risk of being killed by an asteroid is higher than an airplane crash for most people I believe.

comment What is the nature of magnetism within and without the Galatic plane?
I can't see what problems people have with this question. It's asking about the relative strength and morphology of the Galactic magnetic field compared with that of the Earth.

Except that the most abundant "metals" are in fact non-metals.

I don't think either answer you cite claims that Kirchoff and Bunsen invented the terminology.

comment What is the best catalog of black hole candidates?
@tau1777 sounds like another Q. There are only a couple of stellar BHs that have been found dynamically. All the rest are X-ray or GW sources.
