B Positive Energy Theorem Explained in Layman Terms

[windy miller]

Can anyone explain what the positive energy theorem is layman terms ?

What do you mean by "layman terms"? I mean what do you expect as an answer? I suppose the wiki article is not what you are looking for?

Well maybe we could start with a physical interpretation of the dominant energy condition, what is that and how does it differ from the other strong and the week energy condition?

Where have you tried to look for this information already? Have you looked in any textbooks? Most of the standard GR textbooks discuss the energy conditions and what they mean physically.

Even Wikipedia's discussion is not too bad as a starting point:

@bcrowell's free-to-download textbook on GR discusses the energy conditions in fairly plain language in section 8.1.3 (p307 or thereabouts).
