During the period of inflation the universe may have briefly

During the period of inflation, the universe may have briefly expanded at 10^{30}1030 ( a million trillion trillion) or more times the speed of light. Why did this ultra rapid expansion not violate Einstein\'s special relativity, which says that neither matter nor communication can move faster than the speed of light.? 1. The universe does not expand through spacetime. Only things moving through spacetime are limited by the speed of light. 2. The universe was too small for the speed of light to make any sense. 3. It does violate Einstein\'s theory of special relativity. Nothing can move faster than light. 4. The universe had negative mass making it tachyonic in nature.

Solution

1. The universe does not expand through spacetime. Only things moving through spacetime are limited by the speed of light.

this is the reason why it not violet the special theory of relativity

as it moves through the sped of 10^30 times this shows that only the inner things are moving at that speed the space is not expanding with the given speed at that time
