“Everywhere there is incessant relative change in position throughout the universe, and the observer is always at the centre of things.”

— Giordano Bruno

Cause, Principle, and Unity (1584)
Context: This entire globe, this star, not being subject to death, and dissolution and annihilation being impossible anywhere in Nature, from time to time renews itself by changing and altering all its parts. There is no absolute up or down, as Aristotle taught; no absolute position in space; but the position of a body is relative to that of other bodies. Everywhere there is incessant relative change in position throughout the universe, and the observer is always at the centre of things.

“All change is relative. The universe is expanding relatively to our common material standards; our material standards are shrinking relatively to the size of the universe. The theory of the "expanding universe" might also be called the theory of the "shrinking atom."”

Arthur Stanley Eddington (1882–1944) British astrophysicist

[…] Let us then take the whole universe as our standard of constancy, and adopt the view of a cosmic being whose body is composed of intergalactic spaces and swells as they swell. Or rather we must now say it keeps the same size, for he will not admit that it is he who has changed. Watching us for a few thousand million years, he sees us shrinking; atoms, animals, planets, even the galaxies, all shrink alike; only the intergalactic spaces remain the same. The earth spirals round the sun in an ever‑decreasing orbit. It would be absurd to treat its changing revolution as a constant unit of time. The cosmic being will naturally relate his units of length and time so that the velocity of light remains constant. Our years will then decrease in geometrical progression in the cosmic scale of time. On that scale man's life is becoming briefer; his threescore years and ten are an ever‑decreasing allowance. Owing to the property of geometrical progressions an infinite number of our years will add up to a finite cosmic time; so that what we should call the end of eternity is an ordinary finite date in the cosmic calendar. But on that date the universe has expanded to infinity in our reckoning, and we have shrunk to nothing in the reckoning of the cosmic being.
We walk the stage of life, performers of a drama for the benefit of the cosmic spectator. As the scenes proceed he notices that the actors are growing smaller and the action quicker. When the last act opens the curtain rises on midget actors rushing through their parts at frantic speed. Smaller and smaller. Faster and faster. One last microscopic blurr of intense agitation. And then nothing.

The Expanding Universe (1933)

“Marxist philosophy holds that the law of the unity of opposites is the fundamental law of the universe. This law operates universally, whether in the natural world, in human society, or in man's thinking. Between the opposites in a contradiction there is at once unity and struggle, and it is this that impels things to move and change. Contradictions exist everywhere, but they differ in accordance with the different nature of different things. In any given phenomenon or thing, the unity of opposites is conditional, temporary and transitory, and hence relative, whereas the struggle of opposites is absolute.”

Mao Zedong (1893–1976) Chairman of the Central Committee of the Communist Party of China

On the Correct Handling of Contradictions Among the People
Original: (zh-CN) 马克思主义的哲学认为，对立统一规律是宇宙的根本规律。这个规律，不论在自然界、人类社会和人们的思想中，都是普遍存在的。矛盾着的对立面又统一，又斗争，由此推动事物的运动和变化。矛盾是普遍存在的，不过按事物的性质不同，矛盾的性质也就不同。对于任何一个具体的事物说来，对立的统一是有条件的、暂时的、过渡的，因而是相对的，对立的斗争则是绝对的。

“A heightened control of the affects, developed in society and learned by the individual, and above all a heightened degree of autonomous affect control, was needed in order for the world-picture centred on the earth and the people living on it to be overcome by one which, like the heliocentric world-picture, agreed better with the observable facts but was at first far less satisfying emotionally; for it removed human beings from their position at the centre of the universe and placed them on one of many planets circling about the centre.”

“Throughout history, people with new ideas—who think differently and try to change things—have always been called troublemakers.”

“The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them.”

Leonardo Da Vinci (1452–1519) Italian Renaissance polymath

The Notebooks of Leonardo da Vinci (1883), XV Astronomy
Context: The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them. And any one standing on the moon, when it and the sun are both beneath us, would see this our earth and the element of water upon it just as we see the moon, and the earth would light it as it lights us.
