comment A Neutron Star and an Atom are Similar
But if this really is the mechanism for your "millisecond pulsar", doesn't this answer in the affirmative the question of whether a charge radiates when accelerated by gravity? I thought that was still an open question.

comment A Neutron Star and an Atom are Similar
@rob jeffries yes you are right, I misread the density on Wikipedia. That brings my frequency down to 2 kHz which is in your ballpark; and of course also brings the speed down below c.

comment Why doesn't a lighter flame cast a shadow?
If they emit light in the visible range, then they must also absorb light in that range. That's how it works. If it were different, you could construct a closed system where heat flows from low to high temperature.

doesn't sound right to me. If a flame can emit light, then it can also absorb light.

comment Why is the trajectory of the alpha particle in a cloud chamber almost straight?
You're assuming the alpha particle actually has to strike the nucleus directly. What about coulomb scattering, which is effective over a much larger cross-section?

comment Why isn't a meter defined from a kilogram of water?
Except you'd have to worry about how much deuterium was in the water. That's a complication.

comment Why isn't a meter defined from a kilogram of water?
Contrary to the comments so far, this is a very good question. We could have defined a kilogram as the standard mass of so-and-so many hydrogen atoms, and then the definition of the meter could have followed as the linear dimension of one cubic megagram of water at 4 degrees celsius. The density of water would have been 1.000 by definition. Instead, we have to determine the density of water by experiment, from the standard meter and the standard kilogram. So how close is it to 1.00 anyways?

comment Is Wikipedia wrong about Huygens-Fresnel Principle?
The business of anomalous behaviour in two dimensional seems like a huge red herring which is irrelevant to the question at hand. It is not even mentioned in the Wikipedia article which I am calling into question. According to that article, Fresenel needed to make an angular compensation correction even in regular 3-space. I just don't buy it.

comment Is Wikipedia wrong about Huygens-Fresnel Principle?
If's there's only one wavefront, then it does propagate both ways, forwards and backwards. You need the whole forward-moving wave train to cancel out the backwards-propagating waves.
