<human>: Recently I have been revising for my Physics exam so when I've been taking a break I've been watching physics related videos on YouTube which lead me onto one about the theory of parallel Universes, which got me thinking. In the video they said about how the interaction between particles would spark of into separate 'branches' where in one branch they interacted and the other they didn't thus creating an infinite amount of branches over time, and in each of these 'parallel universes' they laws of physics as well as laws of everything else are slightly different where in out universe pi=3.14 but in another if could equal 2 or even 45, which made me think of the idea that in one of these universes the concept of parallel universes would be impossible (if there is an infinite amount of universes then one must have this concept) then if this was the case, then that would make the whole concept of this impossible, as if one of the universes has the laws of physics saying its impossible, then it has to be impossible in every other one, rendering them all incorrect and whole concept implodes on itself...

Provide a brief overview of the text.
<bot>: Parallel universe idea, what if the laws of physics in a  universe said that the idea of parallels couldn't exist rendering all universes wrong
