Astronomers using the James Webb Space Telescope have observed extremely distant LRD galaxies, with redshifts greater than 14 at distances greater than 13.5 billion light-years. The question I raise here is how do we see these galaxies and their spectral features if the universe is less than 10,000 years old?

Does the fact that we see light from very distant galaxies prove that the one-way speed of light is finite? Dr. Jason Lisle responds to this question. The conventionality thesis plays a critical role in understanding the issue, suggesting that measurements usually assume an isotropic light speed.
