This is interesting, and I would like to find out more about it. That equation with the Del & T is meaningless to me, since I don't know what the letters stand for. A search for "energy-momentum conservation" turns up lots of college physics labs about energy conservation and momentum conservation.
Can anyone help me find out more?
Also, I have read that Newton's three laws of motion, if suitably formulated so that they are meaningful in a non-euclidean space, and being careful to say "derivative of momentum", NOT "mass times derivative of velocity", continue to be exactly right, as far as modern physics is aware. But since Newton's laws essentially say, "momentum is conserved", that would not be true if this article is correct (right)?
