Photons in Electromagnetic Interactions
- Colin Cumming
I know that it's hard to visualize, but it works the same way. When it comes to repulsion, you can think of two people facing each other, throwing a basketball back and force. Throwing the ball and catching the ball pushes the people further apart. (This becomes very clear when you place these two people in separate boats on a lake. The boats will move away from each other.) Well, in Einstein's four-dimensional quantum world of space and time, you can have the same process with negative energy. In the macroworld, this would lead to the two people/boats moving closer together. I've seen a graphic explaining it in this way: Think of two people facing AWAY from each other. Now one of them skillfully launches a Frisbee in a nice curve that lands directly in the hands of the second person. In this case, both people experience a "kick" that pushes them (and their boats) toward each other.
