What is time?


Eternalism (philosophy of time): Time is only a concept. The future moves into the past leaving no time for the present. When the relativity of time is understood as merely a concept for the measurement of apparent change, then there is only the present moment, which is eternity itself.

Higher dimensions from string theory



String Theory predicts the existence of more than the 3 space dimensions and 1 time dimension we are all familiar with. According to string theory, there are additional dimensions that we are unfamiliar with because they are curled up into tiny complicated shapes that can only be seen on tiny scales. If we could shrink to this tiny, Planck-sized scale we could see that at every 3D point in space, we can also explore 6 additional dimensions. This animation shows a Calabi-Yau surface which is a projection of these higher dimensions into the more familiar dimensions we are aware of.
