 Expanding space has significant implications for measuring distance. Here we are zooming into GNZ-11, the most distant object ever found. The galaxy's redshift, combined with Hubble's law, gives us the distance the light traveled, 13.4 billion light years. And we know the speed of light, so the time traveled was 13.4 billion years. We normally say that the galaxy is therefore 13.4 billion light years away. But during its long travel time, space expanded considerably. In fact, GNZ-11 was less than 2.7 billion light years away from us when the light started its journey. And the galaxy is now over 30 billion light years away. In order to calculate these distances, we need to know how the universe expanded during the light's journey. Note that if a galaxy is far enough away, its apparent velocity will be faster than the speed of light. And its light would never reach us. It would be beyond the physical visible horizon for the universe. It's not that it is moving through space that fast. It's just that more space is being created per second between us and them than light can traverse in one second. Plugging in the numbers, we find that all galaxies beyond 14 billion light years could never be seen here. GNZ-11 is now 32 billion light years away, so the light that is leaving GNZ-11 now will never reach us.
