2 giorni fa · Etymology and terminology The term zero-point energy (ZPE) is a translation from the German Nullpunktsenergie. Sometimes used interchangeably with it are the terms zero-point radiation and ground state energy. The term zero-point field (ZPF) can be used when referring to a specific vacuum field, for instance the QED vacuum which specifically deals with quantum electrodynamics (e.g ...
3 giorni fa · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
1 giorno fa · In the prevailing Standard Model of physics, the photon is one of four gauge bosons in the electroweak interaction; the other three are denoted W +, W − and Z 0 and are responsible for the weak interaction. Unlike the photon, these gauge bosons have mass, owing to a mechanism that breaks their SU (2) gauge symmetry.

HIGHLIGHTS. What: The authors show that Einstein`s conformal gravity can explain simply and on the geometric ground galactic rotation curves without the need to introduce any modification in both the gravitational as well as in the matter sector of the theory.
4 giorni fa · Higgs’ best rounds came as the weekend progressed. After shooting a one-under 71 in Round 1, he went 67-65-66 the rest of the way. That put him in a tie with Gore, who shot a steady 68-65-67-69.
