Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.
Death by black hole
Of course, no matter what type of black hole you plunge into, you're ultimately going to get torn apart by its extreme gravity and die a horrible death. No material that falls inside a black hole could survive intact.
on edge of Black Hole. Space and time are intertwined, called space-time, and gravity has the ability to stretch space-time. Objects with a large mass will be able to stretch space-time to the point where our perception of it changes, known as time dilation.
If you fell into a supermassive black hole soon after it formed, you would reach the singularity within a few hours. The tidal forces as you approached the singularity would be so powerful and unpredictable that not only would you be torn apart, but so would space and time.
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
A star has survived a close encounter with a black hole, but the black hole has been able to sneak a second bite. A captured star has experienced multiple close encounters with a supermassive black hole in a distant galaxy — and possibly even survived having material ripped away by immense gravitational tidal forces.
They're called 'tidal disruption events'
Astronomers using NASA's Hubble Space Telescope have recorded a star's final moments in detail as a black hole gobbled it up. They're called tidal disruption events.
At the center of a black hole the gravity is so strong that, according to general relativity, space-time becomes so extremely curved that ultimately the curvature becomes infinite. This results in space-time having a jagged edge, beyond which physics no longer exists -- the singularity.
Since nothing can escape from the gravitational force of a black hole, it was long thought that black holes are impossible to destroy. But we now know that black holes actually evaporate, slowly returning their energy to the Universe.
As you might expect, the possibility of time travel involves those most extreme objects, black holes. And since Einstein's theory is a theory of space and time, it should be no surprise that black holes offer, in principle, a way to travel through space, as well as through time.
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape. And then, at the center, is the singularity. That's the word we use to describe a point that is infinitely small and infinitely dense.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of binary systems.
For all practical purposes the matter has disappeared from the universe. Once inside the black hole's event horizon, matter will be torn apart into its smallest subatomic components and eventually be squeezed into the singularity.
One Star's End is a Black Hole's Beginning
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)
Black holes are absolutely silent, as they are creatures of pure gravity. But while black holes produce no sound of their own, they can generate sound waves in their environment.
No human has ever been inside of a black hole. Humans are not yet capable of interstellar travel. Even if a human was able to travel to a black hole, he or she would not be able to survive entering it. Black holes condense all the matter that falls into it into one point called a quantum singularity.
Black holes are dark, dense regions in space where the pull of gravity is so strong that nothing can escape. Not even light can get out of these regions.
Our galaxy's supersized black hole, Sagittarius A*, as seen by the Event Horizon Telescope. It contains the equivalent mass of 4.3 million Suns and lies about 26,000 light-years away.
A black hole is an extremely massive concentration of matter, created when the largest stars collapse at the end of their lives. Astronomers theorize that a point with infinite density—called a singularity—lies at the center of black holes.
A single Black Hole, even one at the center of our Milky Way galaxy, is just too small to eat an entire galaxy.
The diet of known black holes consists mostly of gas and dust, which fill the otherwise empty space throughout the Universe. Black holes can also consume material torn from nearby stars. In fact, the most massive black holes can swallow stars whole.
Micro black holes, also called mini black holes or quantum mechanical black holes, are hypothetical tiny (<1 M ☉) black holes, for which quantum mechanical effects play an important role.
