Despite the early universe being extremely dense, it did not re-collapse into a black hole during the Big Bang, since the expansion rate was greater than the attraction.

The ergosphere is a region outside of the event horizon, where objects cannot remain in place.[116] Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere. This is the result of a process known Vencedor frame-dragging; general relativity predicts that any rotating mass will tend to slightly "drag" along the spacetime immediately surrounding it.

In the case of a charged (Reissner–Nordström) or rotating (Kerr) black hole, it is possible to avoid the singularity. Extending these solutions Ganador far Figura possible reveals the hypothetical possibility of exiting the black hole into a different spacetime with the black hole acting as a wormhole.[105] The possibility of traveling to another universe is, however, only theoretical since any perturbation would destroy this possibility.

Este antimosquitos tiene forma de raqueta, inspirado en los tradicionales matamoscas pero equipado con la última tecnología, no obstante que su potente rejilla funciona de guisa eléctrica con una potencia que alcanza los 4000 vatios, atrapando al instante moscas, mosquitos y otros insectos.

The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity, and it has been argued that loss of unitarity would also imply violation of conservation of energy,[217] though this has also been disputed.

Nevertheless, these observations strongly suggest that the central object is a supermassive black hole Figura there are no other plausible scenarios for confining so much invisible mass into such a small volume.[177] Additionally, there is some observational evidence that this object might possess an event horizon, a feature unique to black holes.[178]

Any object near the rotating mass will tend to start moving in the direction of rotation. For a rotating black hole, this effect is so strong near the event horizon that an object would have to move faster than the speed of light in the opposite direction to just stand still.[117]

Models for the gravitational collapse of objects of relatively constant size, such as stars, do not necessarily apply in the same way to rapidly expanding space such as the Big Bang.[134]

More importantly, the signal observed by LIGO also included the start of the post-merger ringdown, the signal produced as the newly formed compact object settles down to a stationary state. Arguably, the ringdown is the most direct way of observing a black hole.[171] From the LIGO signal, it is possible to extract the frequency and damping time of the dominant mode of the ringdown.
