Should we really rely on this principle as heavily as we do? I have good reason to think that this statement is incorrect. My first question I would like to ask is if matter cannot be created, how does it exist?
At this point, you will hear various responses. The most common one is that "Matter that exists has always existed, and was not created by anything because in order to have been created it must first have not existed." It's a fair point, but lacks any evidence to support. Why would we so readily accept the notion that all matter has always existed in some form, when we can not logically explain how something can exist without being created? While I do not deny the possibility that this statement is accurate, I cannot give it any more weight than I give to the theory that matter was created, but came from nothing. If we do not have any substantial evidence showing which of these theories is more plausible, than how we can so matter of factly state that matter cannot be created? I believe this is a serious scientific error that will eventually prevent us from making progress in knowledge unless we change our perspective. So I ask these forums for someone to attempt to provide me with a more convincing arguement to accept this principle of matter.

What we call "matter" is "created" and "destroyed" all the time. There is however some more fundamental reality which is not created or destroyed but sometimes "appears" to have properties we call "matter". "Matter" is really some kind of an energy field. The total amount of energy and certain other properties may be conserved in a system. Some of that energy apears as "matter" at least under certain conditions.

I would only add the possibility of that which transcends human perception or understanding completely.

Well then; how would we know of it??? If we concentrate on what we can know we are bound to be in better shape at the end of the day...Science and technology take turns waiting on each other, and together they extend human perception far beyond what the past could imagine... So why imagine when for us it is fantasy... Let the geeks do their geeky things and report in triplicate later... learn what we already know...
