Inception brought us the alteration of space, the three initial dimensions, by putting mind over matter. Okay, the matter was essentially mind, but still, space and it's physical properties got altered in this movie to the extant of a possible penrose-staircase.
But Nolan, my name sharer, didn't stop there, with Interstellar he multiplied Inception by Infinity. Seriously, if you want to know what's the next higher dimension, put the one you have now next to it over and over again infinitely and you get it.
So what happens if you stack space onto space onto space until you have a string of which every point is a whole spacial universe?
Did I hear time? You, you there, you said it. Admit it, you said time. And it's right. Fourth Dimension is the illusion of time created by an infinity of spacial universes speeding through as we count a millionth of a millionth of a millionth of a second.
Well, and what happens towards the end of Interstellar? Exactly, mind is put over matter again, but also over time, when the tesseract , an object with infinite mass and existent in every point in space, is used as a fivedimensional shortcut to his daughter he was said to never see again because of lightyears, distances and shit. They didn't see the tesseract coming. Or, as Doc Brown would put it, they're not thinking four-dimensionally!
So, where am I going with this? Well, Folks, we were given a trailer and if you didn't already see the new Dr. Strange trailer, I recommend you to do that, because we have just gotten higher by a dimension.
Update (26.07.2016):
So, the new trailer was released *thinkthinkthink* three days ago and we finally see more about it, like it also including four-dimensional movement/travel! :bademoticon:
I so will go see this movie...
