“At first glance, it may appear odd that the black hole loses mass upon absorbing another mass-that of the electron. Actually, this… — Henning Genz Copy Share Image
“Considering the energy balance, the reduction in size and the rise in temperature of the black hole form a feedback mechanism that… — Henning Genz Copy Share Image
“We don't really know whether there are black holes that emit observable amounts of Hawking radiation. Nevertheless, there is no way to… — Henning Genz Copy Share Image
“If they were as we described them, the existence of black holes would contradict the principles of thermodynamics. One of these principles… — Henning Genz Copy Share Image
“We have good reason to believe that space and time begin to merge into quantum mechanical uncertainty at distances this small; they… — Henning Genz Copy Share Image
“If all of the presently observable universe pooled its matter to create one giant black hole, its radius measured in light-years would… — Henning Genz Copy Share Image
“In order to show that not even light can escape from the gravitational pull of a black hole, we have to hone… — 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
“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 Image
“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 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
“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 Image
