– is it an accepted truth the universe is expanding?

376 views

Isn’t this idea included or a product of the Big Bang Theory?

The second part of the question is, how come there are new galaxies being discovered if the universe is expanding faster than the speed of light?

Does light travel an infinite amount of distance? Isn’t luminosity or intensity of light a thing?

Is there any possibility that light itself degrades over time and the wavelength simply gets redshifted because of wave decay rather than the space its travelling through becoming stretched? I think it could be plausible lets get a scientician to do a study. Just need a lab 12bn ly long and we can test it.
