2 Chapter 1:Multiple Universes Coexisting

In my stories there will be more than one universe and these universes numbers are uncountable. But no matter how many universes there are,they will always be connected to one singular timeline. The reason for that is in order to travel or inneract with other universes without dimensional tiering(which I will talk about later) you need to have the exact same time. Here is an example:if a being from Universe 1 wants to talk with his/her Universe 2 equivelent and travels to that universe,if the date in Universe 1 is 12/03/2017 afternoon,the date in Universe 2 is also going to be 12/03/2017 afternoon. No matter how much more advanced or simple that universe is.
