Grains of Space and Time

In the Planic scale ( after Max Planck ) atoms and normal time scales are huge. As huge as sun is to an atom and as huge as a nano second is to the age of the Universe.

At the Planic scale, both space and time are not continuous, but grainy. Theory of relativity assumes space is continuous and efforts are on to produce a grainy theory of relativity.

The grainy universe is a consequence of Heisenberg's uncertainity theory.

Looking at Planck time:

Light, travelling over very long distances, would have to spread out a bit if there was any uncertainty in time . So measure the spread and you know the uncertainity and the graininess of time.
