I have a question concerning what has been proven about the properties of light over billions of years and billions of light years.
Specifically, is it assumed/proven that light waves stay the same over billions of years as they travel through space? (Disregarding the other influences like doppler, gravitation redshift, etc.)
How would you prove that?
How can we no with absolute certainty that it's not a natural property of light to redshift over billions of years, considering all the other influences that effect light (doppler, gravitation, etc.)?
Thanks for answering to a laymen who has a "hunch".
