The thread discusses the apparent contradiction of ultra-distant galaxies moving at speeds close to the speed of light, based on redshift measurements, and explores the implications of this phenomenon in the context of relativity and cosmology.

Ask Ethan: How can ultra-distant galaxies move so fast?

If you translate redshift into a special relativity velocity, you'll find the most distant galaxy, MoM-z14, speeds away from us at 99.2% the speed of light.

How is that possible?
