This seems testable enough... The speed of light isn't in question here, so the frequency is the yardstick. Can't we just record the frequencies given off by the elements every hundred years or so and see that they are the same?
- madaxe_again 8y agoThat’s true, as with this cosmology light evidently isn’t affected by the increase in rest mass, as photons are massless. If this cosmology affected relativistic mass, then light would also be affected and would not be seemingly redshifted by the mass gain mechanism. So, yeah, we should be able to measure a gradual emission spectrum shift here on Earth with current methods - we can measure energies of photons to very high precision, and you’d likely only need a few years of data to prove or disprove the hypothetical cosmology.
- api 8y agoWe should do it then. Maybe nobody ever looked because we assumed these things to be invariant.
- fragsworth 8y agoNot necessarily, because the currently accepted theory is that the universe is expanding at an accelerating rate. The frequencies should change in both models.
