Re: Explain Mass.
Mass is energy in motion. A particle at rest has no mass. But when it picks up speed it acquires mass. Mass is not matter. Matter is a concept. If you fall off the roof and hit the ground, your molecules are not bumping into each other. They are impacting force fields.
I've been struggling with this for years. It still isn't intuitive. How is it that when I look at something, I see something, rather than "empty space," which is what is all there is?
