How? What if after 100 years light has a small chance to disappear.
- sandworm101 3y agoBecause very distant objects describe a very different universe, meaning the light has traveled in time without degrading. For instance, the cmb doesn't match the current universe, proving both that light travels forever and that the universe is not static. Distant objects also do not show degradation in brightness beyond square area expectations. They are redshifted, but not dimmer than would be normal.
