Re: Light vs neutrons - aren't all that different?

Correct.
"90% of everything is crap" guideline suggests that encountering crap should not be a surprise.
So when I saw crappy claims in that video -- I was not surprised.

I do not understand what you are asking.

1) Light cannot escape gravity because gravity pulls on it as a particle.
2) It is not obvious.
3) I still do not see the connection between that talk about the curvature and why light cannot escape.

Ok.
But how does it prove that gravitational impact on light should not be considered separately from gravitational impact on mass?
