That isn't actually completely true. Mass("Matter") can be converted to energy, which is done daily in nuclear reactors to turn a tiny amount of phsical mass from a nuclear fuel into heat in a nuclear reactor. Scientists have also found that a high enough energy electromagnetic wave can spontaneously convert to matter in the form of an electron and its anti-matter opposite (positron), this is called pair production and is such so cool when you think that its the first step to a Star Trek transporter or replicator.SpiritInTheWater wrote:Science says: Matter can neither be created, nor destroyed.
The other rule not mentioned is that Energy may not be created or destroyed only changed in form. (Like the wave converting to matter for instance). This rule could someday also be proven incorrect but it has worked quite well and I find even as a scientific minded person that it works well with the concepts of spirits. While I may be wrong in a spiritual sense, we as entities do not have a fixed amount of energy throughout life. If that were true we wouldn't have to eat would we. We wouldn't grow from youth and we wouldn't fade with old age. I find it quite reasonable that as an entity lives its energy transfers out into the spaces around it, just as it absorbs the energies into itself (through eating, warmth, etc). If our spiritual energy transfers out into space in such a way that it results in waves of echo, like a rock thrown into a lake causes waves, then it makes great sense to me that a piece of us remains in areas that we have existed.
Just my thoughts on the matter (heh didn't mean to make the matter pun there)
