BLACK HOLE

                           BLACK HOLE                              

   CONTEXT:- 

The first photography of a black hole was revealed by scientists recently.

ABOUT BLACK HOLE:-

# A black hole is an object in space that is so dense and has such strong gravity that no matter or light can escape it's pull. 

# Because no light can escape, It is black and invisible.

SINGULARITY:- 

# There's boundary at the edge of a black hole called the event horizon, which is the point of no return - any light or matter that crosses that boundary is sucked into, and used to travel faster than the speed of light to escape, which is impossible.

# Anything that crosses the event horizon is destined to fall to the very centre to the black hole and squished into a single point with infinite density, called the singularity.

SIZE OF BLACK HOLE:- 

# Small black hole called stellar-mass black hole. They have masses similarly to those of large star 🌟 about five to time the mass of sun ⛅.

# The other kind is supermassive black hole, which are million's to billions of times more massive than the sun ⛅.

# There size can be extremely small because of the high density.

WHERE ARE BLACK HOLE FOUND:-

# supermassive black hole are found at the centre of most galaxies including our own milky way.

# The one is our galaxy is called Sagittarous A* and is one of those the event horizon telescope has been attempting to photography.

HOW THE BLACK HOLE FORMED:- 

# Supermassive black hole are believed to form at the same time as the galaxy that surrounds them , but astronomers aren't sure exactly how.

# Stellar-mass black hole form when a star 🌟with a mass greater than three times that our sun ⛅ runs out of fuel.

# It explode into a supernovae and collapses into an extremely dense core that know as a black hole.

# Which was predicted by Albert Einstein general theory of relativity.
