comment Is Gravity Energy?
Well, that's the question: do they? We can track the energy of the electrostatic field via E^2 dV, and when field energy disappears it reappears as kinetic energy of the charged particles. Gravity is different. If we calculate the square of the gravitational field and integrate it over space, we get something that looks like the electric field energy. But if we drop a stone to the ground, the kinetic energy increases and at the same time, the square of the field energy also increases. So you can't keep track of energy changes by looking at the field. It's very different from electrostatics.

Cool simulation. Well done.

Oh come on now. There is no accelerating charge in the ground state of the hydrogen atom and everyone knows that.

comment Common false beliefs in Physics
It's hard for me to understand what you are trying to tell me. In what interpretation are the charges accelerating in the ground state of hydrogen? More to the point, when you say "this is not correct" I'm wondering if you can identify one specific error in what I said?

Aaron, while I believe my last edit was technically correct, I have concluded that it does not really address your actual problem. So I am going to edit my answer one more time...

Yes, you're right again. I'm going to revise my answer for the third time.

comment Focusing light into an optical fiber cable
Okay, I must be wrong, because it is true that using a magnifying glass, I can make an image of the sun that is smaller than the actual sun.

comment Focusing light into an optical fiber cable
Those seem like related issues. If I can make a smaller image by collecting light over a certain solid angle, then can I not make multiple images in different places, collect them with optical cables, and concentrate them into a single reduced volume?
