Im not sure what point you are trying to make with the sun and radiant energy. The sun's energy cannot exist in two places at once. When you burn a piece of wood the majority of the potential energy stored within it is released to its surroundings via heat and light. Once it is in thermal equilibrium with its environment it is "burned out". Likewise the sun heats the earth through a fusion reaction, transmitting the energy to the planets and the far reaches of space as radiation and light. As there is no medium in the vacuum of space, radiation and light is the only means of energy transfer. The sun is not an infinite supply of heat and light, albeit incredibly large it will at some point go out. This is a process of entropy as everything in the universe is moving torwards a state of thermal equilibrium.
I agree personal energy is not relevant, because its not energy rather information. It would be the arrangement of electrons that makes you "you". This leaves the realm of thermodynamics and ventures into quantum physics and the way the world is arranged. I personally feel the soul is something that cannot be measured or clearly defined with science
I am a little a.d.d. and a.d.h.d. so my post might sometimes ramble or jump subject,sorry.
with radiant energy, since energy cannot be created, when radiant energy is given off/split from the source it is in essence
in two places at once.
