A Redshift Lookup Table for our Universe
The light from distant galaxies gets stretched by the expansion of the universe. We call this redshift, and it tells us how far away a galaxy is. This table maps redshift to distance, showing us how the universe has expanded since the light left its source. It is a fundamental tool for understanding the cosmos.
