Anything is possible within the laws of physics. It's interesting to note that if the multi-verse is truly infinite, then an event that happens every second (like a heart beat), or an event that happens every billion years (perhaps like the beginning of a universe), would both occur an infinite number of times! No difference between the two events from the perspective of infinity...
I agree with Tyler here. But I also believe that the physists today dont know all the laws of physics, there are still many more laws to discover. With that being said, I believe if we knew all the laws of physics, everything would have to obey the known and unknown laws of physics. What Im candidly saying is that there there is a science to everything, and everything can be explained by science except maybe feelings, emotions, the human psyche, etc.
I also believe in the multiverse, or many, many universes. If one universe can be created from nothing, then whos to say a seemingly infinite amount of universes cant also be created from nothing?- if space is indeed infinite like I believe.
Also, if space is infinite then what is anything in comparison to infinite space? We are all infinitely small, a dot within a dot, within a dot, within a dot, etc. Existance truly is a divine miracle.
If time is infinite also then that would nullify time and we are all just alive for a blink of an eye, our lives are for a naught amount of time.
