It is so simple, this is the same object seen over 2 places. Think of a fishing tank, the side glass wall and the front glass wall show the same fish. And that's i hope an easy to understand example of an extra dimension, it solves many physics problems add a dimension.. As the fish swims in the tank, both walls show change in position to and no need for communication at all, its just one fish.

you need proof for extra-dimensional existence just take all those experiments that could be solved by it .. double split... spooky action .... and many more.. (even quantum computers inner working)
