Yes, but all forms of energy REQUIRE matter in order in exist. The wavelenghts of light are somewhat of an exception, but that's because light is simulataneously both matter and energy at the same time, so it more or less can effect itself. If it can exist totally without matter, than it is matter.
Are you saying you know what all forms of energy in the universe are?
No, but I am saying that I know what energy itself is. I don't have to know what every form of insect in the world is to know that a cat isn't one.
Find any example of any kind of functional device or form, nature or artificial, however simplistic, that consists of energy with no matter. I can guarantee that there isn't one, because it isn't possible, but go ahead and try to prove me wrong.
To be serious for a minute. What is our soul? Energy, something like a ghost. Everything there is is a form of energy one way or another. And when we die our souls will be released from our bodies and supposedly, from popular religion, go to heaven or hell. But that is based on belief. What about the people who believe in incarnation? They don't go to heaven until they reach their final incarnation and die, and hell is earth for them. I think that if you believe, deep down, that you will go to heaven or hell, you'll go there. I think that if someone seriously, really deep down believe that if they die, they weill become energy and be a part of everything, everywhere.
And how, pray tell, does a soul qualify as energy? Can you measure it? Can you quantify it? Can you identify it's source or what it effects? If you believe in the soul, as I do, then you should know that it doesn't fit at all any definition of matter or energy. Therefore, it must be neither, but something else entirely.
