[crackpot link deleted] I came across this document when I did a Goggle on theories that violate the conservation of energy law. As I read about Einstein he felt it necessary to look at every ting cynically, even universally accepted laws such as those developed by Newton. Later on I also read that as he was working on a theory one of the requirements was that it did not violate the conservation of energy law. I wondered if there were theories that attempt to reconsider this law. This paper states that not only are their ideas how this law can be violated but presents some examples of when it is violated. Other than the expanding universe example I have to think the others seem to be more of a marketing gimmick than a factual representation. So is this document at least partially valid? Are there theories that attempt to dispute the conservation of energy law?
