Sure it can, since THE LAWS OF PHYSICS DID NOT EXIST, or at least broke down due to the singularity which became our universe. If the laws are broken down, then there is nothing stopping it.
Also, WHY CAN'T IT BE ******* ETERNAL? Pegg that is a question you, and everyone else on this site has yet to answer. Why can't the universe be infinite in time, with no beginning or end? As in you can go as far back in time as you wish, and you will constantly find another cause, and another and another... but you will never find the first. Is that hard to understand? Well it doesn't matter. Just because you cannot understand it does not mean it's wrong.
