“Light is an excitation of empty space proper, of the vacuum. It is no more and no less.” — Henning Genz Copy Share Image
“It is impossible to bring a substance down to a temperature of absolute zero; there cannot be a blackbody without radiation because… — Henning Genz Copy Share Image
“There is no suchthing as absolutely empty space. All space contains fluctuating fields and particles. Even in the emptiest space that the… — Henning Genz Copy Share Image
“What really transcends our understanding is the mechanism that permits these oscillations of abstract field quantities to carry energy. We know this… — Henning Genz Copy Share Image
“A space that is empty in the sense that it doesn't contain masses is nothing but a special case of the above.… — Henning Genz Copy Share Image
“As long as two fields that describe one and the same space are identified, the field and the space can be used… — Henning Genz Copy Share Image
“John Maddox, the editor of the British journal Nature, had immediately suggested that the minister should be told that the Higgs boson… — Henning Genz Copy Share Image
“Second, what properties distinguish an otherwise empty volume that retains only some black-body radiation at zero temperature-dubbed zero-degree radiation-from truly empty space?… — Henning Genz Copy Share Image
“We can now infer that at this initial cooldown of the universe across the critical temperature of 10^15 degrees, a mini planetary… — Henning Genz Copy Share Image
“Theory and experiment both show us that light does not need a material medium for propagation. We would have no trouble understanding… — Henning Genz Copy Share Image
“In microscopic systems-such as in an atom, a molecule, a crystal-this minimal energy means internal motion of its constituents. It is independent… — Henning Genz Copy Share Image
“Of all conceivable reasons for some sequence of physical events Plato recognizes only its ultimate aim as worthy of attention. The world… — Henning Genz Copy Share Image
“By reversing the steps that we took to advance from the concept of substance to that of Materia Prima, we can imagine… — Henning Genz Copy Share Image
“The elementary particles are often dubbed the atoms of our day. That may or may not be correct. It might be an… — Henning Genz Copy Share Image
“As we showed in figure 5, water molecules oscillate about their rest positions in ice. Quantum mechanics says that this remains true… — Henning Genz Copy Share Image
“LIGHT AS AN EXCITATION OF SPACE Let's try and understand light in terms of an excitation of empty space-even if that makes… — Henning Genz Copy Share Image
“The field of the electron is real because it results from the laws of quantum mechanics and appropriate initial conditions. The laws… — Henning Genz Copy Share Image
“Insofar as the general theory of relativity follows Mach's ideas, it can be seen as expressing the distribution of masses in terms… — Henning Genz Copy Share Image
“We recall that the term inflation stands for the explosive growth of the universe by a factor of 10^50 in the time… — Henning Genz Copy Share Image
“The Higgs field originated as the universe cooled down after the Big Bang-a bit like the crystallization of ice as water cools… — Henning Genz Copy Share Image
“Bodies influence the space that surrounds them; they tell us whatever we can learn about that space. Does this mean that, possibly,… — Henning Genz Copy Share Image
“Small regions of empty space will see large energies appear in the form of these fluctuations. they may be energetic electromagnetic waves.… — Henning Genz Copy Share Image
“We know that the uncertainty relation implies not only the absence of empty space but also the nature of the minimal content… — Henning Genz Copy Share Image
“Recall our discussion of the pendulum. Its position at a given instant does not fix its subsequent behavior. Suppose a photograph shows the pendulum… — Henning Genz Copy Share
“Just as with sound waves, light waves emitted by a moving source show the Doppler effect. What we observe instead of the sound pitch… — Henning Genz Copy Share
“The interpretation of apparent long-distance action by means of continuously propagating effects was vigorously asserted by Isaac Newton. In his wake, the interpretation of… — Henning Genz Copy Share
“The quantity that physicists call the specific heat of a substance is defined as the amount of energy needed to raise the temperature of… — Henning Genz Copy Share
“To gain any intuitive understanding of the breakdown of this ultimate symmetry through vacuum effects at the critical 10^-44 seconds after the Big Bang,… — Henning Genz Copy Share
“To illustrate this relation, think of a game of table tennis. As the ball hits the table, it will bounce up and down. When… — Henning Genz Copy Share
“Before the particles that we observe today materialized, all matter in the early universe must have gone through this stage of a quark-gluon soup,… — Henning Genz Copy Share
“In physics terms, the reason for symmetry breaking is the instability of the symmetric state.” — Henning Genz Copy Share
“What really transcends our understanding is the mechanism that permits these oscillations of abstract field quantities to carry energy. We know this is true;… — Henning Genz Copy Share
“Chaotic or disordered distributions are symmetrical on the average. An observer cannot conclude anything about his location from looking around him. An example is… — Henning Genz Copy Share
“The hotter a substance, the faster and the less ordered its molecular motion, and the larger the momentum with which molecules collide. Above 0… — Henning Genz Copy Share
“This elementary process is symbolically illustrated in figure 59c: A photon becomes an electron-positron pair; inversely, an electron and a positron can combine into… — Henning Genz Copy Share
“John Maddox, the editor of the British journal Nature, had immediately suggested that the minister should be told that the Higgs boson can be… — Henning Genz Copy Share
“At first glance, it may appear odd that the black hole loses mass upon absorbing another mass-that of the electron. Actually, this seeming paradox… — Henning Genz Copy Share
