2. WHAT IS BLACK HOLE?
• Black Hole is a region in space where the light and not even particle can escape from
it.
• Black Hole contain such a strong gravitational effect.
• The general theory of Relativity can sufficiently predicts that how to form a black
hole.
• Black Hole contain a large amount of energy and even matter also.

3. HOW CAN DETECT BLACK HOLE?
• As a name Black Hole is black so we cannot detect easily.
• There are many types of method to detect Black Hole.
• Black Hole emits particular wavelength of light which can be detect in Telescope.
• The boundary of in space where no escape can possible is known as “Event Horizon”.

4. • The Quantum Field Theory in curved space-time indicates that the event horizon emits
Hawking Radiation.
• Black Hole can consider as perfect Black body.
• There are many types of Black Hole like Massive Black Hole, Tiny Black Hole.
 The Massive Black Hole contain a large amount of energy as well as the mass of one
spoon of Tiny Black Hole is equal to the mass of huge mountain on the Earth.

5. • The stellar Black Hole creates when very massive star is collapse at the end of its life cycle.
• After created Black Hole, it continuous to growing and absorbing mass from its surroundings.
• Most galaxies are contain a Massive Black Hole in its center.
• If any star of planet is orbiting around Black Hole, the path of the object in spiral shape.
• So that scientist can easily determine the location of Black Hole.

6. • LIGO’s (Laser Interferometer Gravitational wave Observatory) scientists are detect
Gravitational wave which is formed by merging Black Hole.
• LIGO’s scientists succeeded in detection of Gravitational wave on 11 February, 2016.
• As well as the second time was detected Gravitational wave on 15 June, 2016.

7.  The first Black Hole was found by Karl Schwarzschild in 1916.
 The region of gravitational fields are too strong for light can’t escape from it were first
considered in 18th century by John Michel and Pierre-Simon Laplace.
