T'Mau was a scientist who's work was known by the 23rd century

According to Professor T'Mau's theory, to determine how many dimensions connected to the primary universe was dependant on how many dimensions were shared by the two universes. However, Professor On-dy-Ango's theory, which was never proven, contradicted T'Mau's. A notable problem with T'Mau's scientific study was that it did not explain the slingshot effect.
