Black holes, as we currently understand them, are a product of general relativity. The concept of something resembling a black hole was first introduced by John Michell in 1783 based on Newtonian physics. Michell imagined a star or similar object whose escape velocity was greater than the speed of light. Such an object would be invisible at a distance because any light emitted from it would fall back to it. If black holes were like this, it would be theoretically possible to escape one by simply accelerating, no matter how far in you fell. General relativity shows that this is not the case. According to general relativity, gravity is a product of mass distorting space and time. This distortion becomes quite severe around a black hole. Within the radius where the escape velocity is equal to the speed of light, the distortion becomes so severe that the only possible path forward in time is toward the center of the black hole. Nothing that crosses within this event horizon can ever come back out.

What theory is used in describing black holes?
Our modern understanding of black holes is based on the General Theory of Relativity.
Did Albert Einstein figure out what black holes are?
The modern understanding of black holes, or at least the initial calculations, were not figured out by Albert Einstein, but by Karl Schwarzschild (based on Einstein's General Theory of Relativity).The modern understanding of black holes, or at least the initial calculations, were not figured out by Albert Einstein, but by Karl Schwarzschild (based on Einstein's General Theory of Relativity).The modern understanding of black holes, or at least the initial calculations, were not figured out by Albert Einstein, but by Karl Schwarzschild (based on Einstein's General Theory of Relativity).The modern understanding of black holes, or at least the initial calculations, were not figured out by Albert Einstein, but by Karl Schwarzschild (based on Einstein's General Theory of Relativity).
What forces black holes?
The existence of black holes is an outgrowth or prediction of General Relativity, which was Einstein's theory of gravitation. The dominant force forming black holes is the force of gravity, a universal attraction between mass.
What are Stephen Hawking's discoveries?
he discovered that by using quantum theory and general relativity he was avle to show that black holes can emit radiation.
Who is rotating black holes named?
Roy Kerr, a mathematician from New Zealand, discovered the solution to the equations of general relativity that describes a rotating black hole.
Can a white hole die?
no. but if you are worried about this, check in with a doctor just to make sure
Who invent black hole?
As a natural phenomenon, black holes were not invented, but they are first known to have been theorised in the 1780s by John Michell. The current concept of a black hole, based on general relativity, was first posited by Karl Schwarzschild in 1916.
How did scientists come up with all this information about black holes?
Scientist first formulated it from the laws of physics (namely relativity) and figured out what affect they would have on the space around them. Once they figured out what the effect would be, they looked out in space and saw the effect, thus proving black holes.
What physical theory first predicted the existence of black holes?
The general theory of relativity, proposed by Einstein in 1916, embodied the notion of gravitation, a phenomenon derived from a local curvature of spacetime. One profound implication, an outgrowth of the field equations of the theory, was the existence of black holes.
What is the general theory relativity?
The general theory of relativity was published by Albert Einstein in 1916. It describes gravitation as a geometric property of space and time. It implies the existance of black holes as the death state of massive stars. It predicts the existence of gravitational waves and is the basis of current models of a consistently expanding universe.
Did Albert Einstein discover anything in space?
Not exactly, he was not an astronomer. However his theory of general relativity predicted the existence of black holes (which has since been confirmed) and wormholes (still unconfirmed)
When did stephan hawking find out what black holes were?
Most likely in the University classroom as an undergraduate student, that's where most people of his generation learned about black holes. But of course what he learned about was ordinary stellar black holes.It was much later when he made his own "what if" hypothesis on microscopic black holes. After solving the equations of general relativity for this case and including the effects of quantum mechanics, he made his theory including Hawking Radiation, evaporation of black holes, and their eventual explosion. This remains theoretical, as his black holes have still not been observed.
