I was unaware of any theory that postulates more than three space dimensions. Even the 12 dimensional Heim Extended Quantum Field Theory has only three space dimensions. The rest are “time-like”.
This is nine miles over my head, so I’m not pretending to understand it. But I looked it up and, if I got it right, “Bosonic” string theory, which is an early version of string theory, postulated 25 spatial dimensions and one time, and though not in favor, is still being studied.
So does this refute brand theory, or is the relevant scale of the collapsed dimensions all wrong?
