How has E=mc2 affected me?

Well, that is a good question. I work with "energy" all day in that I do bodywork. I work with my energy and my clients. I wonder how this equation fits into that activity. If I am low energy does that have something to do with mass? I guess thinking about how this equation affects me in everyday life leads to more questions.

On another level, there is something that I don't, but probably should, think more about. And that is nuclear energy. When I was in college there was a series of concerts on the east coast, the No Nukes concerts. I think there was a lot more awareness around the treat of nuclear weapons and nuclear energy back then. Seems like the issue has gotten a bit quiet. I am more concerned with the general acceptance of nuclear energy. I don't think we have handle on how to deal with the waste. The idea of radioactive material being transported by train or truck, close to where people live and the idea of radioactive waste leaking into our environment really scares me.

Compare the Four Forces:

The Four Forces are similar in that they define the relationship between objects, large and small. The two nuclear forces, the weak nuclear force and the strong nuclear force are very big, but there impact is over a very small distance and limited to the particles of an atom. Electromagnetic forces are also relatively big, but impact objects over a greater distance. Gravity is the weakest of the forces and impacts larger objects over great distances as well. Gravity doesn't fit into the quantum perspective.

What is the function of gravity?

The function of gravity is to define acceleration which gives us a guide to how objects are attracted to and connected to each other.
