Correct me if I'm wrong, but the only real evidence showing that the universe is expanding (and accelerating it's expansion) is by observing the so called "standard candle" supernovae which always have the same luminosity and observing that the farther they are, the more red shifted their light is, and since red shift indicates that an object is moving away from us, we assume that the whole universe is expanding, is this an accurate description?
Isn't also equally plausible that there is some sort of electromagnetic influence on some properties of light which on long time scales will make the light more red shifted?
In other words, we assume that the universe is expanding because the farther an object is, the more red shifted it is, and by having such theoretical construct we are assuming that light is unchanged, that the properties of light are a constant (I'm not referring to the speed of light here), what I'm questioning is that, when light travels across space for billions of years, it should be expected for it to suffer some interference in it's wavelenght.
And if this notion can be sustended by current understanding, wouldn't it somewhat invalidate the whole lambda cdm cosmological model, and in effect the big bang theory itself?
