The way you spell Berenstain Bears might suggest you're from an alternate universe.

Somehow, there's a mess going on regarding the Berenstain Bears, and an internet belief over how you spell their name. Do you spell it Berenstain or Berenstein? A or E?

In the end, it might mean you came from a parallel universe some believe.

According to one, the spelling of our beloved Berenstain Bears is actually more complex than you realize (Feel free to skip ahead of the passage, because I'm not sure what the hell he's saying--except the Berenstain Bears are from another dimension, or you are, or me, or I'm not sure--am I sniffing glue?)(Try to stay awake.):

I propose that the universe is a 4-dimensional complex manifold.  If you don't se habla math jargon, that means I propose the 3 space dimensions and the 1 time dimensions are actually in themselves complex, meaning they take values of the form a+ib, part "real" and part "imaginary".  Within this 4D manifold, there are sixteen hexadectants (like quadrants, but 16 of them), corresponding to whether we consider only the real or imaginary part of each of the four dimensions.  In our particular hexadectant, the three space dimensions are real, and the time dimension is imaginary.

If the above sounds weird to you, please remember that the original proposal of special relativity by Einstein and Minkowski (and others) explicitly treated time as a strictly imaginary coordinate in pseudo-Euclidean space.  It is only modern formulations that have turned to Minkowski space with signed metric tensors.  Also, imaginary time dimensions show up again in quantum field theory to relate quantum path integrals to statistical mechanical path integrals, this done by means of a Wick rotation.

So the concept isn't foreign to physics, was used early on to help get special relativity started, and has shown up since to help quantum field theory to calculate things.

Within this complex spacetime, all mass is shared, and also wave functions of particles are shared, so that effects can leak between them.  This may account for dark matter and dark energy.  Because the imaginary coordinates in a plane wave will turn it in to a decaying function (e^ik(ix) = e^(-kx), which goes to zero as x increases), mostly particles hang out in their own hexadectant and don't leak out.

I further propose that the stEin and the stAin universes are actually just different hexadectants of the same universe: in the stEin universe, all three spatial dimensions are real and time is imaginary; in the stAin universe, all three spatial dimensions are imaginary and time is real.  Of course, from the standpoint of stEin/stAin this won't produce any mathematically significant difference; it's the same as choosing (+++-) or (---+) convention for Minkowski space, which at the end doesn't alter predictions or measurements.  We'd never know if we did swap.
