If the Universe is flat and the total energy of the universe can be zero (we don't know if it is, but many theorists support the idea, i.e. at BB initial conditions: t = 0, V = 0, E = 0) then is it possible that all matter in the universe could have emerged from nothing? If so, that what is the total energy of the matter compensated by?
Just in case, sorry for my English =)Thanks to all in advance.
Edit: Yes, I've watched the lecture by Lawrence Krauss, and I know about his book. Haven't read it though (will be too hard for me, I suppose).
Edit2: @Ahmadi, @Alfred Centauri. Thanks for the answers. But i didn't get it fully. The laws of physics are just notions, abstractions, terms invented by people to describe the processes and regularities in our universe. The law of gravity comes to the scope due to the force of gravity (i know that sounds very primitive, but let's just abstract the details away just for know). Isn't the force of gravity a reciprocity of particles (bosons) between fermions? How can any of the 4 fundametal forces come to scope without existance of particles? Then, where have this particles emerged from? If you say they emerged due to the gravity or some law, then we end up with a circular reasoning.
