Can tessering actually happen in reality as it does in A Wrinkle in Time?

In ,
"tessering" refers to traveling in the fifth dimension, allowing the traveler
instantaneously to cover hundreds of thousands of light years in three-dimensional
space.

Could this happen in reality? Theoretically, yes. String theory and
M-theory have posited up to eleven dimensions, and we have clear mathematical descriptions of
the fifth dimension. The tesseract or "four-dimensional cube" from which
"tessering" takes its name is well established in geometry, and many physicists
believe that higher dimensions are the answer to some of the most fundamental problems of the
universe (in particular, the creation of a unified field theory, which would combine quantum
mechanics with general relativity).

The discovery of a unified field theory
might make "tessering" possible, but it would probably still be beyond human
understanding until our brains develop into something quite different. As Michio Kaku notes,
even physicists and mathematicians who have worked with the notion of higher dimensions for
years admit that they are quite unable to envisage these dimensions. Although
"tessering" might theoretically be possible in the future, we would probably have to
wait a long time for our brains to catch up to the point where we can envisage
it.
