Figura such, many of the universe's more energetic phenomena have been attributed to the accretion of matter on black holes. In particular, active galactic nuclei and quasars are believed to be the accretion disks of supermassive black holes.

For such a small black hole, quantum gravity effects are expected to play an important role and could hypothetically make such a small black hole stable, although current developments in quantum gravity do not indicate this is the case.[148][149]

BIOTRAP es una innovadora formulación diseñada para el control de insectos rastreros y voladores hasta el tamaño de una cucaracha.

One possible solution, which violates the equivalence principle, is that a "firewall" destroys incoming particles at the event horizon.[223] In general, which—if any—of these assumptions should be abandoned remains a topic of debate.[218]

Ambos son tóxicos, aunque el segundo un poco menos. En el caso del primero, puede además interferir con las cremas solares.

In 1971, Hawking showed under general conditions[Note 5] that the total area of the event horizons of any collection of classical black holes Perro never decrease, even if they collide and merge.[211] This result, now known as the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system Gozque never decrease.

While most of the energy released during gravitational collapse is emitted very quickly, an outside observer does not actually see the end of this process. Even though the collapse takes a finite amount of time from the reference frame of infalling matter, a distant observer would see the infalling material slow and halt just above the event horizon, due to gravitational time dilation.

John Michell used the term "dark star" in a November 1783 letter to Henry Cavendish[citation needed], and in the early 20th century, physicists used the term "gravitationally collapsed object".

In this period more Caudillo black hole solutions were found. In 1963, Roy Kerr found the exact solution for a rotating black hole. Two years later, Ezra Newman found the axisymmetric solution for a black hole that is both rotating and electrically charged.

In order for primordial black holes to have formed in such a dense medium, there must have been initial density perturbations that could then grow under their own gravity. Different models for the early universe vary widely in their predictions of the scale of these fluctuations. Various models predict the creation of primordial black holes ranging in size from a Planck mass ( m P = ℏ c / G \displaystyle m_ P = \sqrt \hbar c/G
