The hypothesis of Big Bang is still predominates today but have more and more difficulties. Too many galaxies, galaxies too mature, galaxies have active nucleus due to very big black holes appeared faster than galaxy may be formed — all those facts discovered by James Webb Space Telescope seems to bring the Big Bang idea to the end. But the important question appears: what is instead? One of the old ideas resurrected now is tired light hypothesis. Indeed, there is no process found in the nature so far that has absolutely zero friction — the slow loss of energy by that or this mechanisms is present everywhere. Why would light be an exception (and the present understanding of light is counting on this assumption). However, the initial idea of tired light is not possible — the electromagnetic path to lose energy will not help (see the article). So the idea is to have light losing energy in very small steps — in this situation the energy loss is possible to explain while preserving the other properties of the observed light from the far galaxies. This idea also easily explains the "active" nuclei of the far galaxies by the direct observation of the light scattering in the vacuum. This scattering is actually too strong for gravitation and way too weak for electromagnetic force, so the fifth force is possibly involved here.
