The universe could be cyclical, Big Bang, expansion, then collapse of the cosmic event horizon due to Hawking radiation until the universe hits a minimum size, a black hole containing all of the information in the universe on its event horizon, and then rebounding to create a brand new Big Bang.
Those results suggested that anyone falling into a black hole would be burned up as they crossed its edge - the so - called event horizon.

Hawking and two collaborators claim that the contents of a black hole are inventoried on a hologram on its boundary, the event horizon.
Event horizons, and the paradoxes that go with them, do not exist because the laws of physics guarantee that imploding stars self - destruct before they can become black holes.
As G2 swings closer to the black hole's event horizon — the point past which even light can not escape — gravity has already stretched its leading edge into a ribbon more than 90 billion miles long, pulling it away from the tail, which isn't yet feeling the black hole's full effects.
Four decades ago, he realized that a black hole's event horizon is inherently leaky; quantum processes allow a slow but steady flow of particles away from the black hole, a process now known as Hawking radiation.
According to general relativity calculations, as one passes the event horizon (the point of no return) of a black hole, space and time switch roles.
Applying this to event horizons, they say that individual particles of Hawking radiation are linked via wormhole to the inside of the black hole.

Galaxies also contain millions of small - and medium - sized black holes, each with an event horizon past which light is never seen again.
In the far, far future, when black holes have devoured almost all the matter in the universe, leaving little else to consume, energy should slowly leak out from their event horizons.
If all goes well, as early as next year a virtual telescope with the sensitivity of an Earth - sized radio dish will deliver images of a bright ring of hot gas surrounding a circular shadow: the heart of a black hole, bounded by the event horizon.
PULLED IN The event horizon is framed by the bright ring in this black hole simulation.
If you are unfortunate to fall into a stellar black hole, you will pass the event horizon and probably crash into the black hole itself in a blink of an eye.
Plus, the outside astronaut can potentially piece together everything that fell into the vast black hole interior just by monitoring the event horizon.
The Nottingham experiment was based on the theory that an area immediately outside the event horizon of a rotating black hole — a black hole's gravitational point of no return — will be dragged round by the rotation and any wave that enters this region, but does not stray past the event horizon, should be deflected and come out with more energy than it carried on the way in — an effect known as superradiance.
Physicists could accept that all the properties of all the particles within a black hole were locked up, forever inaccessible to those outside a black hole's event horizon.
It said that an astronaut falling into a black hole won't notice anything special as he crosses the event horizon.
Today some of the best minds in physics are fixated on the event horizon, pondering what would happen to hypothetical astronauts and subatomic particles upon reaching the precipice of a black hole.
An optical analog of the event horizon of a gravitational black hole can be produced with light pulses propagating along an optical fiber, providing a tractable experimental system.
It is usually assumed to be a black hole with an event horizon, but if it is instead a naked singularity, then at least one existing instrument could tell.
Leonhardt is best known for his work on how metamaterials can be used to fashion invisibility devices and how fiber optics can be used to produce analogs of the event horizon, the point of no return in black holes.
Black holes emit no light, so to get the shot, the radio telescope array will focus on the hot gas circling the event horizon that surrounds the tiny target.
Last year Hawking made headlines for saying «there are no black holes» — although what he actually meant was a little more complicated, as he proposed replacing the event horizon with a related concept, an apparent horizon.
This has the same effect as a black hole's event horizon, the point of no return for light: an observer outside an event horizon could see nothing inside, as no light can escape the black hole's gravity to cross the horizon to the universe outside.
The event horizon is the sphere around a black hole from inside which nothing can escape its clutches.
Physicist Brian Greene explains how properties at the black hole's surface — its event horizon — suggest the unsettling theory that our world is a mere representation of another universe, a shadow of the realm where real events take place.
The event horizon surrounding a black hole means nothing, not even light, escapes.
The edge of the newly formed black hole, the event horizon, is the start of...
The answer depends on whether you view the black hole from the outside or from the inside — and from the outside, there's good reason to believe that information is indeed stored at the event horizon.
He saw the black hole's event horizon, the point beyond which nothing can escape; and an accretion disk, the gathering of matter siphoned from nearby stars.
And the reason you can get energy out of a black hole, that swallower of all things, is that the energy you detect never really got into the black hole to begin with — it's associated with the space - time whirlpool created outside the event horizon by the black hole's rotation.
In some way, the black hole's event horizon — the spherical boundary demarcating the points of no return for objects falling in — keeps a record of how much a black hole has eaten.
If you were to watch from a distant spaceship as a clock fell into a large black hole, you would see it ticking more and more slowly, and at the event horizon it would stop altogether.
At the event horizon, Hawking realized in 1974, one particle in a pair can fall into the black hole while the other escapes.
