“The physicist's concept of nothing—the vacuum… began as empty space—the void… turned into a stagnant ether through which all the motions of the Universe swam, vanished in Einstein's hands, then re-emerged in the twentieth-century quantum picture of how Nature works.”

—  John D. Barrow

“Void is when there is absolutely nothing there and the nothing is natural, a complete vacuum. But empty - with empty, you are aware of what's supposed to be there. Empty means something is missing.”

“The quantum revolution showed us why the old picture of a vacuum as an empty box was untenable.”

John D. Barrow (1952–2020) British scientist

...Gradually, this exotic new picture of quantum nothingness succumbed to experimental exploration... in the form of vacuum tubes, light bulbs and X-rays. Now the 'empty' space itself started to be probed. ...There was always something left: a vacuum energy that permeated every fibre of the Universe.

“[speaking about a Persian rug…] how modern their conception of space was! They understood it in the seventeenth century; we are only just beginning to re-understand it in the twentieth – see how they mesh the vines, the tendrils, the flowers with space and utilize these linked forms to create wholeness and radiance.”

“It is quite easy to include a weight for empty space in the equations of gravity. Einstein did so in 1917, introducing what came to be known as the cosmological constant into his equations. His motivation was to construct a static model of the universe. To achieve this, he had to introduce a negative mass density for empty space, which just canceled the average positive density due to matter. With zero total density, gravitational forces can be in static equilibrium. Hubble's subsequent discovery of the expansion of the universe, of course, made Einstein's static model universe obsolete. …The fact is that to this day we do not understand in a deep way why the vacuum doesn't weigh, or (to say the same thing in another way) why the cosmological constant vanishes, or (to say it in yet another way) why Einstein's greatest blunder was a mistake.”

“Einstein entertained counterintuitive notions that allowed him to pull physics from the mechanistic, clockwork universe of the eighteenth century up into the twentieth century.”

“It must be admitted that among a certain number of advanced mathematical physicists whose work has lain mainly in the twentieth century, the ether is regarded with suspicion, or even with contempt. And some of the opponents go so far as to as to say that the nineteenth century idea of the ether has failed to establish itself, and that in consequence the whole idea of the ether is under a cloud, and that it is only upheld by a few antiquated supporters, who, though are willing to admit many modifications in the original nineteenth century notions of an ether, feel the need of a medium capable of performing the functions attributed to it.”

“There's no evidence whatsoever that Darwin had anything useful to say or anything to say period about how life began or how the universe began or how gravity began or how physics began or fluid motion or how thermodynamics began. He had nothing to say about that whatsoever.”

“…when the experiment was attempted by Michelson and Morley it failed, thus showing that space and time assumed in the picture were not true to the facts of nature. …the pattern of events was the same whether the world stood at rest in the supposed ether, or had an ether wind blowing through it at a million miles an hour. It began to look as though the supposed ether was not very important in the scheme of things… and so might as well be abandoned. But if the bell-rope is to be discarded, what is to ring the bell?”
