“At the end of inflation, just as after the hot Big Bang, the universe is hot. It is, we might say, self-created… — Henning Genz Copy Share Image
“Let's return to Archytas's staff and to the expanding Universe. A javelin that is thrown straight upward will drop back down a… — Henning Genz Copy Share Image
“The energy that was hidden in the false vacuum is liberated in the course of this phase transition of the universe into… — Henning Genz Copy Share Image
“The same energy density that we reach today in electron-positron collisions pervaded the entire universe one ten-billionth of a second after the… — 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
“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
“Galaxies, quasars among them, are interpreted by astrophysicists in terms of probes that are attached to points in space and that move… — 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 Image
“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 Image
“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 Image

“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 Image
“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 Image
“In physics terms, the reason for symmetry breaking is the instability of the symmetric state.” — 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 is true;… — Henning Genz Copy Share Image
“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 Image
“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 Image
