Bonus: numarul ala se poate calcula macar?

Da, se poate calcula. Cu unealta potrivită. Și celălalt număr, dar cu unelte ceva mai scumpe.

Dupa "observable or not" nu mai am nicio idee despre ce se vorbeste, sincer sa fiu, daca ma poate lumina cineva as fi recunoscator.

Radiatia de tip Hawking detectata intr-un aranjament experimental analog unei gauri negre: New horizons for Hawking radiation

La calculatoare un zero echivaleaza cu un byte

Nope, recent a fost observata radiatia Hawking: http://www.scientifi...wking-radiation

Physicists in the field disagree about exactly what the observation means. Ulf Leonhardt of the University of St. Andrews in Scotland, whose group in 2008 proposed the optical method of producing event horizons that Faccio and his colleagues used, says that the new research indeed represents the first observation of Hawking radiation.
But others are not as certain. "I still need to be convinced that what they are seeing is the analogue of what Hawking found for black holes," says William Unruh, a physicist at the University of British Columbia who has demonstrated a classical, or nonquantum, analogue of Hawking radiation in the lab by studying the propagation of waves on moving water surfaces. One possible issue is that the Faccio group's photons emerge from the glass at a 90-degree angle from the direction of the laser pulse. "That is the wrong direction, and it is really hard to see how that could happen," Unruh says.
The direction of emission is "a major point of ongoing discussion," Faccio says, noting that the position of the photon detector was chosen to minimize contamination from the laser. "I sort of prefer to think of it the other way around?we have a spectrum of photons that agrees exactly with theoretical predictions for the event horizon. Now we need to properly understand in detail why they're generated."
Ted Jacobson of the University of Maryland remains on the fence as well, noting that although the emitted photons have some attributes that would be expected from an analogue of Hawking radiation, other predicted features have yet to be confirmed. For instance, the experiment performed by Faccio's group does not allow the researchers to verify that the photons appear in quantum-mechanically correlated pairs at the event horizon.

Nu este nimic sigur, doar supozitii. Pana una-alta Universul pare ca se va indreapta cate o acumulare de gauri negre situate la distante din ce in ce mai mari una de alta. Care vor exista la infinit.
Sau pana ce Creatorul acestui Univers decide sa faca altceva din el.

Conform radiatiei Hawking, gaurile negre se evapora intr-o anumita perioada de timp. Daca nici lumina nu poate scapa de gravitatia imensa a unei gauri negre, cum scapa particulele eliminate prin procesul de evaporare?
