With the James Webb telescope detecting more and more extremely distant galaxies, the Big Bang theory is breaking down more and more every day.
So, to try to generate tools to continue the Big Bang theory, another theory is being used, the theory of “tired light”. What is this? It's the idea that over long distances, light slows down and tends towards the red, so that the distances calculated by common rules are greater than they really are. And so, with this kind of analysis, the Big Bang theory would be saved.
The idea is that light collides with other energy sources and loses energy. The big problem with this would be that, if this were true, the image would be blurred, because the particles collide and change the angles of the light, which would end up damaging the image. And this doesn't happen when viewing these stars over long distances.
But satellite systems can capture the light of distant galaxies. If the tired light theory were true, the consequence would be that we wouldn't be able to see these galaxies.
Therefore, the tired light theory is something that would go against itself, because if you can see distant galaxies, then what would generate the tired light couldn't exist, because you wouldn't see the galaxies.
