- Our Milky Way Probably Has a Black Hole.
- Dying Stars Lead to Stellar Black Holes.
- There are Three Categories of Black Holes.

- The First Black Hole Wasn’t Discovered Until X-Ray Astronomy was Used.
Which Indian gave black hole concept?
C. V. Vishveshwara (6 March 1938 – 16 January 2017) was an Indian scientist and black hole physicist. Specializing in Einstein’s General Relativity, he worked extensively on the theory of black holes and made major contributions to this field of research since its very beginning.
Which country invented black hole?
A black hole is a volume of space where gravity is so strong that nothing, not even light, can escape from it. This astonishing idea was first announced in 1783 by John Michell, an English country parson.
What fact about black holes did you find most interesting?
Black holes are the only objects in the Universe that can trap light by sheer gravitational force. Scientists believe they are formed when the corpse of a massive star collapses in on itself, becoming so dense that it warps the fabric of space and time.
What is unknown about black holes?
Black holes extend time, and once you are inside one, time stands still. So how do you make one? You can’t get any information from a black hole in order to make one. The reason is that a black hole has an escape velocity equal to the speed of light so no information can escape.
Which Indian scientist is known as a missile man?
A.P.J. Abdul Kalam
Abdul Kalam, in full Avul Pakir Jainulabdeen Abdul Kalam, (born October 15, 1931, Rameswaram, India—died July 27, 2015, Shillong), Indian scientist and politician who played a leading role in the development of India’s missile and nuclear weapons programs.

Who named black holes?
astronomer John Wheeler
Albert 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.
Who saw the first black hole?
British astronomers Louise Webster and Paul Murdin at the Royal Greenwich Observatory and Thomas Bolton, a student at the University of Toronto, independently announced the discovery of a massive but invisible object in orbit around a blue star over 6,000 light-years away.
Are black holes hot?
Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.
What are the facts about black holes?
Black Hole Facts. They are massive objects – collections of mass – with gravity so strong that nothing can escape, not even light. The most common types of black holes are the stellar-mass and supermassive black holes. Stellar-mass black holes are created when massive stars explode, leaving behind a black hole with the mass of just a few suns.
What is the biggest black hole in the Milky Way?
Famous Black Holes. Sagittarius A*: the supermassive black hole at the heart of the Milky Way Galaxy. It lies in the direction of the constellation Sagittarius. This black hole contains the mass of about 4 million suns. M87: this elliptical galaxy has a 3.5 billion solar-mass black hole at its heart.
Can we see the future through a black hole?
26. Because gravitational time dilation takes place near Black Holes, if anyone can take a spaceship and orbit around the Black Hole (of course along the event horizon) and then travel back to Earth, the person will actually see future.
