As established in Cube2, in a Tesseract alternate realities could exist side by side.
This raises a question. Is there 1 room, or the same room folding in on each other constantly?

What do you think?
I personally think that the Tesseract is more than 1 room, like the first Cube facility, but the rooms CAN fold in each other, because Kate managed to jump Simon from the opposite side of the room.

i believe there are at least 3 rooms but they keep folding in on each other so it seems like there is an infinite number of rooms. an example of when the rooms folded in on each other was the time when the colonel was.... burnt, vapourised, pwned? by the moving wall and when the alternate simon was killed by the moving columns.

But then if they were 3 rooms, where would the dead Max and Julia, what about that room with all of them dead in it?
I suppose they could be Alternate Realities, like Alternate Simon.
The colonel got pwned - Love it! Although, for the sake of correctness, a room with a time signature faster than the one he was in moved in to that room, making him age rapidly.
