If the expansion of space in the macrolevel is faster than the speed of light then it should have "more" than infinite rapidity. How does that work out?
Thanks.
Thanks.

The FTL (faster-than-light) expansion of space refers to the theoretical idea that the universe is expanding faster than the speed of light. This concept is based on the theory of cosmic inflation, which suggests that the universe underwent a rapid period of expansion in its early stages.
Einstein's theory of relativity states that nothing can travel faster than the speed of light, so the idea of FTL expansion of space may seem contradictory. However, this concept does not involve matter or energy traveling through space, but rather the expansion of the fabric of space itself.
At this time, there is no direct evidence for FTL expansion of space. However, there is strong evidence for cosmic inflation, which is a key aspect of this theory. Scientists are currently conducting further research and observations to try and gather evidence for FTL expansion of space.
If FTL expansion of space is occurring, it would mean that the universe is much larger and older than previously thought. This is because the expansion of space would have happened at a much faster rate in the past, stretching the universe to its current size in a much shorter time period.
If FTL expansion of space is possible, it would have significant implications for space travel. It could potentially allow for faster travel between distant points in the universe, but it also raises questions about the limitations and consequences of surpassing the speed of light.
