20 Things You Didn't Know About... Nothing

1 There is vastly more nothing than something. Roughly 74 percent of the universe is “nothing,” or what physicists call dark energy; 22 percent is dark matter, particles we cannot see. Only 4 percent is baryonic matter, the stuff we call something.

2 And even something is mostly nothing. Atoms overwhelmingly consist of empty space. Matter’s solidity is an illusion caused by the electric fields created by subatomic particles.

3 There is more and more nothing every second. In 1998 astronomers measuring the expansion of the universe determined that dark energy is pushing apart the universe at an ever-accelerating speed. The discovery of nothing—and its ability to influence the fate of the cosmos—is considered the most important astronomical finding of the past decade.

4 But even nothing has a weight. The energy in dark matter is equivalent to a tiny mass; there is about one pound of dark energy in a cube of empty space 250,000 miles on each side.

5 In space, no one can hear you scream: Sound, a mechanical wave, cannot travel through a vacuum. Without matter to vibrate through, there is only silence.

6 So what if Kramer falls in a forest? Luckily, electromagnetic waves, including light and radio waves, need no medium to travel through, letting TV stations broadcast endless reruns of Seinfeld, the show about nothing.

7 Light can travel through a vacuum, but there is nothing to refract it. Alas for extraterrestrial romantics, stars do not twinkle in outer space.

8 Black holes are not holes or voids; they are the exact opposite of nothing, being the densest concentration of mass known in the universe.

9 “Zero” was first seen in cuneiform tablets written around 300 B.C. by Babylonians who used it as a placeholder (to distinguish 36 from 306 or 360, for example). The concept of zero in its mathematical sense was developed in India in the fifth century.

10 Any number divided by zero is . . . nothing, not even zero. The equation is mathematically impossible.

11 It is said that Abdülhamid II, sultan of the Ottoman Empire in the early 1900s, had censors expunge references to H2O from chemistry books because he was sure it stood for “Hamid the Second is nothing.”

12 Medieval art was mostly flat and two-dimensional until the 15th century, when the Florentine architect Filippo Brunelleschi conceived of the vanishing point, the place where parallel lines converge into nothingness. This allowed for the development of perspective in art.

13 Aristotle once wrote, “Nature abhors a vacuum,” and so did he. His complete rejection of vacuums and voids and his subsequent influence on centuries of learning prevented the adoption of the concept of zero in the Western world until around the 13th century, when Italian bankers found it to be extraordinarily useful in financial transactions.

14 Vacuums do not suck things. They create spaces into which the surrounding atmosphere pushes matter.

15 Creatio ex nihilo, the belief that the world was created out of nothing, is one of the most common themes in ancient myths and religions.

16 Current theories suggest that the universe was created out of a state of vacuum energy, that is, nothing.

17 But to a physicist there is no such thing as nothing. Empty space is instead filled with pairs of particles and antiparticles, called virtual particles, that quickly form and then, in accordance with the law of energy conservation, annihilate each other in about 10-25 second.

18 So Aristotle was right all along.

19 These virtual particles popping in and out of existence create energy. In fact, according to quantum mechanics, the energy contained in all the power plants and nuclear weapons in the world doesn’t equal the theoretical energy contained in the empty spaces between these words.

20 In other words, nothing could be the key to the theory of everything.

    I have read this and officially learned nothing. Thanks.
