There is measurement of time known as Plancks time, which is about 10^-43s (a very, very small period of time). The life of the universe that comes prior to one Plancks time (the universe younger than 10^-43s) is known as Plancks epoch. During Plancks epoch, the known laws of physics simply do not apply. For example, all four fundamental forces (gravity, weak nuclear force, strong nuclear force, and electromagnetism) were likely unified into a single force. It wasn't until after Planks time that the forces began to split. It's not possible to analyze the young universe (a universe younger than Plancks time) using the known laws of physics. This includes the conservation laws, which you are inducing in your post.
So, in short......a young universe could "violate" the conservation laws as, during that time frame, our currently-discovered laws of physics do not apply.
Will we ever know what happened during Plancks epoch? Maybe, maybe not. But the correct course of action is to continue to approach the issue scientifically rather than fall into the infinite regress of a "first cause" argument.
Does this fit in with multiverse and bubble theory? All universi would have the same origin?//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif
