  1. Can someone explain the angular wave number and the angular frequency?
  2. Can someone clarify the meaning of quantum state in the Pauli Exclusion Principle? Does the principle mean that no two fermions can occupy the same place at the same time?
  3. Can someone explain the statement, As the surface of the star is composed of ordinary matter, it must move along a time-like trajectory, sandwiched between inward directed and outward directed light surfaces, ?
  4. Can someone explain the four laws of black hole thermodynamics?
  5. How do you calculate the probability of an event, such as the example attached, within a reasonable amount of time? (The event involves the emission of a photon by an electron, and then the absorption of the photon by another electron. The points where the electron absorbs or emits a photon can be anywhere.)
