I want to clarify, this isn’t “my scenario”, it’s a non-mathematical explanation of what we actually observe right now. When we measure the speed of galaxies far away from us, they’re receding at faster then the speed of light. You have to keep in mind that we are not talking about movement “within” the universe, where stars and matter don’t move anywhere near the speeds of light, we’re talking about reality itself expanding in all directions. We can actually observe the light emitted from those distant galaxies change its color, as the expansion of space causes the actually wavelength of light to expand.
