4 exists in this reality, and yes I occupy all of them same as you. Quantum physics may open up as many a 10 dimensions, but AT THIS MOMENT IN TIME there are only 4.<quoted text>
How many dimensions exist in this realm you occupy? Do you occupy them all sir? Is the list complete or are certain scientists working feverishly in figuring out how to "discover" more dimensions?
Do all the dimensions occupy or exist in the same time/space?
Thats how science works, and thats why the word theory is used, any discovery is subject to change or modification as new information is discovered. A working theory is the best explanation at this moment in time.
