Not true.
So the Academia knows very well that motion is relative.
What Hoyle is saying is that relative motion has no physical significance, physics remains the same. There is no way to say one is real and the other is only apparent, since the only difference is in the frame of reference. There is no experiment that can be performed to tell the difference between the two. Meaning, either performed from Earth or Sun or in space, experiment will always give the same physical conclusions. Movement depends on the frame of reference and that is the matter of convention. Understanding this may lead us to a better understanding of relations, it brings us a step closer to how things really are. Like, when General relativity replaced Newtonian mechanics, it did not disprove it, but overgrew it instead. It is just more general and provides a better understanding, from a perspective on a scale larger than Newtonian. Example is the experiment in which observer from Earth, after seeing that Sun is orbiting Earth, would start elevating from the Earth, and when changing position, he would realize that motion of the Sun is not that simple. The picture changes. That experiment would change no physical laws, it would change only the experience. The only thing left is to make a convention with observers in a different frames of reference. Movement is a convention. Another example is how the Earth would look from the Moon. Here we see that Moon is revolving around us. But from the Moon, Earth would look like a lunostationary satellite. Neither is true, yet both are true.
Another thing worth mentioning here is the relativity of truth. Philosophy went beyond Aristotelian "tertium non datur"or "ït is either true or not true". There are new fields in philosophy, like paraconsistent logics and dialetheism, which allow for a statement to be simultaneously both true and not true. Both views work, the difference is relative.
Philosophy singles it out in Cogito ergo sum.
