Do you get BBC's Horizon? In "What happened before the Big Bang?", Laura Houghton-Mersini was on great form. She's saying one reason for the universe being hotter than expected could be neighbouring universes.
It's not an insult, Janeebee.
If you knew anything about the multiverse, you'd know what p-branes are.
In theoretical physics, a p-brane is a spatially extended mathematical concept that appears in string theory which exists in a static number of dimensions.
The variable 'p' refers to the number of spatial dimensions of the brane.
There may be multiple universes, containing parallel/alternate Janebees.
Have you ever considered that possibility?
If so, then you know that you may already be a p-brane.
