In the superstring theory that successfully unites gravity and quantum mechanics, the universe must have:
A) four dimensions (three spatial and one temporal)
B) six dimensions (three spatial and three temporal)
C) seven dimensions (six spatial and one temporal)
D) nine dimensions (eight spatial and one temporal)
E) 11 dimensions (10 spatial and 1 temporal)

Question

Quizplus · Accepted Answer

According to the superstring theory, the universe must have 11 dimensions - 10 spatial dimensions and 1 temporal dimension. This means that there are six additional spatial dimensions beyond the familiar three that we experience in our everyday lives. These extra dimensions are believed to be too small to be detected by current technology, which is why we do not perceive them directly. The superstring theory is one of the leading theories in modern physics for explaining the nature of reality at its most fundamental level.
