Can we create a black hole?
To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light..
Where do things go in a black hole?
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. As the singularity accumulates more and more matter, the size of the black hole’s event horizon increases proportionally.
How were black holes predicted?
The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein’s theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core.
Who predicted the existence of black holes?
Albert EinsteinAlbert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by American astronomer John Wheeler.
Has anyone been in a Blackhole?
What would happen if you fell into a black hole? It certainly wouldn’t be good! But what we know about the interior of black holes comes from Albert Einstein’s General Theory of Relativity. … Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.
What is inside a Blackhole?
A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
Can a black hole kill you?
The point at which tidal forces destroy an object or kill a person will depend on the black hole’s size. … For small black holes whose Schwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon.
Can you see a black hole?
Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But the holes can nevertheless be seen. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas.
How did Albert Einstein predict black holes?
Einstein denied several times that black holes could form. In 1939 he published a paper that argues that a star collapsing would spin faster and faster, spinning at the speed of light with infinite energy well before the point where it is about to collapse into a Schwarzchild singularity, or black hole.
What did Einstein predict?
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
Can the sun go into a black hole?
Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In about 5 billion years, the Sun will start to run out of hydrogen in its core to fuse, and it will begin to collapse.
Does time exist inside a black hole?
For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.
