If it breaks the laws of physics, it can not be. By this I do not refer the laws that we the Humans have defined, but to the laws that exist and control the universe and that we have only partially figured out and understood. When one law is broken another will take it's place and control it. Everything follows the laws of physics, the common ones that we know and those that we haven't figured.
But if there is infinite amount of universe, infinite space and infinite energy. Any combination can create almost everything, but things that break the laws of reality and physics.
