Given a 3D world (3 linear dimensions and 3 rotational dimension) and a single time dimension, to reverse time in this world, all that is needed is to rotate any one of the perpendicular time dimension outside of the time particle. This gives the illusion that only eleven dimensions are all that are needed to fully describe this world.
Time and space is arbitrary and interchangeable; symmetric, it is possible to live in a 3D time world with a single space dimension. So, time like space can have a full 3 orthogonal directions and 3 orthogonal rotational directions. And to build this world of time and space, requires six plus six, a total of twelve dimensions, six linear and six rotational.
Assumingly, but simplest.
