[72] This means there is no observable difference at a distance between the gravitational field of such a black hole and that of any other spherical object of the same mass. The popular notion of a black hole "sucking in everything" in its surroundings is therefore correct only near a black hole's horizon; far away, the external gravitational field is identical to that of any other body of the same mass.[73]
[5] In many ways, a black hole acts like an ideal black body, Ganador it reflects no light.[6][7] Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum Figura a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.
In the case of a charged (Reissner–Nordström) or rotating (Kerr) black hole, it is possible to avoid the singularity. Extending these solutions Triunfador far Vencedor possible reveals the hypothetical possibility of exiting the black hole into a different spacetime with the black hole acting Figura a wormhole.[105] The possibility of traveling to another universe is, however, only theoretical since any perturbation would destroy this possibility.
No known mechanism (except possibly quark degeneracy pressure) is powerful enough to stop the implosion and the object will inevitably collapse to form a black hole.[130]
Some of the material from the disrupted star forms an accretion disk around the black hole, which emits observable electromagnetic radiation.

The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star. The size of this limit heavily depends on the assumptions made about the properties of dense matter. New exotic phases of matter could push up this bound.[184] A phase of free quarks at high density might allow the existence of dense quark stars,[201] and some supersymmetric models check here predict the existence of Q stars.
These X-ray emissions are generally thought to result when one of the stars (compact object) accretes matter from another (regular) star. The presence of an ordinary star in such a system provides an opportunity for studying the central object and to determine if it might be a black hole.[184]

Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius Ganador indicating that this was the boundary of a bubble in which time stopped. This is a valid point of view for external observers, but not for infalling observers.
The observation also provides the first observational evidence for the existence of stellar-mass black hole binaries. Furthermore, it is the first observational evidence of stellar-mass black holes weighing 25 solar masses or more.[174]
