Imagining the fourth dimension is hard but 6 more dimensions after that is mind boggling. It is all theory though mathematically proved. I couldn’t understand all the dimensions, I gave up on some of them. VIDEO->To help you understand dimensions you should watch Dr.Quantum In Flatland. It explains very well what dimensions are.->
I wonder what the use is of imagining ‘all possible outcomes for all possible universes’ as a dot. It’s a cool thing to think about I guess.
