Zeno, Universe, galaxy, Earth, superluminal, light
We consider the case of light emitted by the after-Earth born galaxy of redshift < 1.5 that travels through space towards the Earth in the non-expanding (Euclidian) Universe or the expanding (Big Bang) Universe. Assuming that the Principle of energy conservation is valid, we conclude that in both cases that light has to be superluminal to reach the Earth.
