*The James Webb telescope has discovered a galaxy with the red shift of 14.44. From that you can calculate that it took light 13.5 billion years to reach us, it started its journey only 280 million years after the Big Bang. And because of the expansion of the universe the galaxy is now 34.7 billion light years from the Earth. What I find really fascinating is that although we can see the galaxy if we tried to send a laser beam to it, because of the expansion of the universe, the beam would NEVER reach it; in fact that's true for any galaxy that has a red shift larger than 1.8, and this one had a red shift of 14.44! * *James Webb telescope breaks its own record again, discovering farthest known galaxy in the universe* <https://www.livescience.com/space/astronomy/previously-unimaginable-james-webb-telescope-breaks-its-own-record-again-discovering-farthest-known-galaxy-in-the-universe> Does a red shift of 1.8 imply recession at light speed? How is that calculated? AG ^aq -- You received this message because you are subscribed to the Google Groups "Everything List" group.
