Black Holes

What is a Black Hole?

To many astrologists, a black hole is a region in space time with a gravitational field that is strong enough so no light can escape from it. Black Holes can be formed from stars with different shapes, magnetic fields, mass distributions and etc. However, according to Shapiro and Teukolsky, once a massive star begins to collapse, nothing can stop it. So as the collapse continues, its gravitational field near the object becomes very strong. Soon, nothing could escape from the object, not even light.

Brief History of Black Holes

Though the term, black hole, was not its common name, its theoretical existence was inspected and observed throughout its years. In fact, the name 'black holes' was introduced by John A. Wheeler in 1967. Not to mention, those who first discussed the existence of Black Holes had an idea that black holes are existent due to a corpuscular theory of light when light cannot escape from an object a fairly large mass and small radius.Around 1915, physicist Karl Schwarzchild gained a general solution for gravitational field surrounding a spherical mass and sent the papers to Einstein to transmit to the Berlin Academy. Unfortunately, no one discovered that his papers contained a complete description of black holes. Also, as the years went on, it wasn't until the early 60's that the theoretical notions of black holes were ignored. But once neuron stars were discovered, astrophysicists had become more observant to Black Holes and their properties, making the study of Black Holes more efficient.
