In physics, any absurdity entails other absurdities. So the expansion of the universe entails that "the wavelength of photons propagating through the expanding space is stretched"
https://en.wikipedia.org/wiki/Redshift. Let us consider this:
Richard Feynman: "I want to emphasize that light comes in this form - particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you probably learned something about light
behaving like waves. I'm telling you the way it does behave - like particles. You might say that it's just the photomultiplier that detects light as particles, but no, every instrument that has been designed to be sensitive enough to detect weak light
has always ended up discovering the same thing: light is made of particles."

In this text Feynman unwittingly suggests:
1. The speed of light varies as per Newton.
2. Variable wavelength of light
https://youtube.com/watch?v=xsVxC_NR64M is an unrealistic wave-based concept.
"The wavelength of light is constant for a given emitter" will become the fundamental axiom of future, Einstein-free physics (if it's not too late to resurrect physics).
