What is invented by Subrahmanyan Chandrasekhar?
Subrahmanyan Chandrasekhar was an astrophysicist. He discovered that massive stars can collapse under their own gravity to reach enormous or even infinite densities. Today we call these collapsed stars neutron stars and black holes.
What is Subrahmanyan Chandrasekhar best known for?
Chandrasekhar — an Indian-born scientist who spent 50 years at the University of Chicago — is most famous for coming up with the theory that explains the death of the universe’s most massive stars. Before Chandrasekhar, scientists assumed that all stars collapsed into white dwarfs when they died.
Who is famous Indian astrophysicist?
Jayant Vishnu Narlikar is an Indian astrophysicist. Narlikar is a proponent of steady state cosmology. He developed with Sir Fred Hoyle the conformal gravity theory, commonly known as Hoyle–Narlikar theory. It synthesises Albert Einstein’s Theory of Relativity and Mach’s Principle.
Why did Subrahmanyan Chandrasekhar get Nobel Prize?
The Nobel Prize in Physics 1983 was divided equally between Subramanyan Chandrasekhar “for his theoretical studies of the physical processes of importance to the structure and evolution of the stars” and William Alfred Fowler “for his theoretical and experimental studies of the nuclear reactions of importance in the …
Who discovered black holes?
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 discovered black holes in 1983?
As a young doctoral student at Cambridge, Subramanian Chandrasekhar had deduced that certain types of stars, called white dwarfs, could not have a mass more than roughly 1.44 solar masses (the Chandrasekhar limit).
Who discovered Milky Way?
Galileo Galilei
Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe….Milky Way.

Who discovered white hole?
The possibility of the existence of white holes was put forward by Russian cosmologist Igor Novikov in 1964.
Which scientist is related to theory of black hole?
In 1916, Karl Schwarzschild found the first modern solution of general relativity that would characterize a black hole. David Finkelstein, in 1958, first published the interpretation of “black hole” as a region of space from which nothing can escape.
