  2. Hawking radiation - Wikipedia

    en.wikipedia.org/wiki/Hawking_radiation

    Hawking radiation would reduce the mass and rotational energy of black holes and consequently cause black hole evaporation. Because of this, black holes that do not gain mass through other means are expected to shrink and ultimately vanish. For all except the smallest black holes, this happens extremely slowly.

  3. Accidental release source terms - Wikipedia

    en.wikipedia.org/wiki/Accidental_release_source...

    Accidental release source terms are the mathematical equations that quantify the flow rate at which accidental releases of liquid or gaseous pollutants into the ambient environment which can occur at industrial facilities such as petroleum refineries, petrochemical plants, natural gas processing plants, oil and gas transportation pipelines, chemical plants, and many other industrial activities.

  4. Black hole information paradox - Wikipedia

    en.wikipedia.org/wiki/Black_hole_information_paradox

    This perspective holds that Hawking's computation is reliable until the final stages of black-hole evaporation, when information suddenly escapes. [30] [31] [44] [12] Another possibility along the same lines is that black-hole evaporation simply stops when the black hole becomes Planck-sized. Such scenarios are called "remnant scenarios".

  5. Black hole thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Black_hole_thermodynamics

    In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...

  6. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...

  7. Effusion - Wikipedia

    en.wikipedia.org/wiki/Effusion

    Effusion from an equilibrated container into outside vacuum can be calculated based on kinetic theory. [2] The number of atomic or molecular collisions with a wall of a container per unit area per unit time (impingement rate) is given by: =. assuming mean free path is much greater than pinhole diameter and the gas can be treated as an ideal gas.

  9. W. G. Unruh - Wikipedia

    en.wikipedia.org/wiki/W._G._Unruh

    Unruh has made seminal contributions to our understanding of gravity, [1] [2] black holes, [3] cosmology, and quantum fields in curved spaces, including the discovery of what is now known as the Unruh effect. Unruh has contributed to the foundations of quantum mechanics in areas such as decoherence [4] and the question of time in quantum mechanics.
