The famous speed limit imposed by Einstein's Special Theory Of Relativity also states that it
applies only to material objects moving within pre-existing space. However, space itself can expand
carrying objects with it and in that expansion it can reach arbitrarily high speeds. That's
precisely what happened in the early universe. In the first few moments of the universe it expanded
faster than the speed of light, with dark energy exerting pressure and forcing acceleration on our
expansion.
Consequently, the edge of the universe is expanding faster than the speed of light. You
can neither see nor interact with it because the light it sends back to us will never reach us.
Amazing, isn't it?
