“To date we know only two real media that offer almost no resistance to moving bodies. One such medium was discovered in… — Henning Genz Copy Share Image
“There is field for every particle. If that field is concentrated in some spatial region, the particle of that field is likely… — Henning Genz Copy Share Image
“In another experiment Guericke connects a small glass sphere that's filled with air with a larger evacuated one. As he opens the… — Henning Genz Copy Share Image
“But it forms the backdrop for Thales' idea that the world arose from the waters. This ur-ocean however to him is not… — 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 Empty space Copy Share Image
“This question about the reason we do not observe any quantum mechanical uncertainty in the appearance of flies or stars was never… — Henning Genz Quantum mechanics 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 Empty space 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 Black hole 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 Black hole Copy Share Image
“Every object is embedded in the vacuum with which physics surrounds it. This means we don't observe the naked object-rather, we see… — 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 Empty space Copy Share Image
“Now let's assume that there is an external Mass acting gravitationally on some system that we observe. Then there are two possibilities:… — Henning Genz Copy Share Image
“At a temperature of 10^10 degrees, the energy of the photons of the electromagnetic/thermal radiation becomes that needed for the creations of… — Henning Genz Copy Share Image
“Whenever liquid water makes the transition to ice, energy is given off to the surroundings. In the process, the water itself assumes… — 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… — Henning Genz Big bang 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 Electromagnetic waves 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.… — Henning Genz Copy Share Image
“Real systems are, in this sense, "excitations of the vacuum"- much as surface waves in a pond are excitations of the pond's… — Henning Genz Real world 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 Empty space Copy Share Image
“The gravitational field of Earth will determine the direction of the rock that you drop from your hand. Aristotle concluded, from the… — Henning Genz Copy Share Image
“The quarks were originally introduced as mathematical symbols-the carriers of certain properties that would facilitate mathematical understanding of elementary particles. This very… — Henning Genz Learning Copy Share Image
“Plato holds a special place among them. His detailed interpretation of matter as a hollow space surrounded by regularly shaped bodies was… — Henning Genz Existence Copy Share Image
“There is no such thing as an indestructible material object. Every particle that meets its antiparticle gives up its identity and becomes… — Henning Genz Copy Share Image
