who exactly is the fool? Is it the one who sees the Sun going down and concludes it is really the Sun that is moving, or is it the one who sees the Sun going down and thinks it is actually the world spinning round?

It is interesting to notice and keep in mind two things we consider in science nowadays: 1. The Earth and the Sun both orbit around one common barycenter which is very close to our star (under its surface, actually) because of its relative mass; 2. The answer of the question "which is spinning around which?" depends on the reference frame; so on Earth's surface, we can effectively say that this is the Sun which is moving. So no one is the fool. Both are right.

If we take a frame of reference linked to another star, we would certainly see the Earth moving around the Sun. How do we know that? Because we observed many different and more exotic stellar systems, and we know that this is always the lighter body which turn around the more massive one.
At 
[according to Einstein:] the two sentences "the Sun is at rest and the Earth moves" or "the Sun moves and the Earth is at rest" would simply mean two different conventions concerning two different coordinate systems

Einstein was working on the incompatibility of Newtonian mechanics with Maxwell’s equations of electromagnetism. The Michelson-Morley experiment showed thatthe so far accepted “luminiferous aether” doesn’t exist. He developed the "Special relativity" theory to correct mechanics to handle situations involving all motions especially closed to the speed of light. The experiments did not show that earth is fixed but rather that the aether as defined until then. doesn't match the experiment..

This is also an accurate quote (page 63 of "The Universe and Dr Einstein") but it is out of context. L. Barnettt said that this was a supposition of the men 400 years ago. The author seems convinced that the Earth is moving with respect to the sun. On the same page: "We know, for example, that the earth is moving around the sun at the rate of twenty miles a second".

Accurate quote from "The Relative Motion of the Earth and the Luminiferous Ether" by Michelson, plublished in the American Journal of Science in 1881. But the end of the sentence is missing: "... which presupposes that the earth moves through the ether, the latter remaining at rest." The hypothesis of an earth at rest contradicts the phenomenon of aberration as well, which is one of the most solid proof that the Earth is moving.
At

It's not how the modern science works. We ask for evidences, and an explanation for all the experiments that seems to prove that the earth is moving. The idea of an earth in the center of the universe is so outdated... Once again: the earth is at rest in its own frame of reference, but is moving in most of the others. The center of the universe doesn't even exist.

It is incorrect to say that "the stars are going around other stars". Except for a few special binary stars, where one very small star goes around a very big one, most of the stars orbits around the center of their galaxy, not around another star. In the Milky Way, this center is a supermassive black hole, Sagittarus A*.

He worked with Heaviside, another physicist who had already tried to understand the electric field for particle affected by a motion close to the speed of light. He did not used the word 'contraction' but tits implication was there. The wording doesn't state that "it shortens its length" but rather "compressed the ether"

The general relativity doesn't state that the earth is at the center of the universe. It provides a geometric theory of gravitation. It encompasses special relativity and refines newton's law of universal gravitation. Hence it explains how any body (mass) travel across the four dimensional spacetime, relating the curvature of spec-time to the energy and momentum.

This is just a misinterpretation of general relativity. The general relativity expands Newton's theory of gravitation with a geometric theory of gravitation. In this theory each independent body evolves linearly along its own spacetime. None of the objects has specific role, being the center of something for example. All celestial bodies elements evolve according to the spacetime as defined by matter and radiation in the spacetime.

The statement just misinterprets the general relativity (and the previous Einstein quote) The general relativity doesn't create any special point in space but rather define that each object has an inertial movement on its own time-space . Therefore each object could be used as its own reference in space understanding that time-space is modified by gravity..

Boyle is just saying that we are defining the center of the solar system as the point (inside the sun) that is the closest to the barycenter of the different objects of the solar system. If someone want s to take another center (of reference) we can also compute and measure the positions and moves of all objects. This is just one of the basic principle of general relativity.
