In the name of God, the Most Gracious, the Most Merciful.
Peace be unto you my dear friends.Welcome to Infopoint.
Our universe is full of MYSTERIES.
Allah Almighty has created many such things
that are so much MYSTERIOUS
Among such MYSTERIOUS things one is Black Holes
According to some researchers these black holes are the way to other universe
And  according to some those are Pit of destruction.
In this video we will try to know the reality of Black holes
So it is requested that kindly watch this video till end

In order to know more about the reality of black holes
we have to understand the concept of "Einstein Theory of Relativity"
According to which
Mass create a bend in Spacetime
Objects with higher densities produce greater bend in space time fabric.
If the density of the object goes beyond the certain limits
then it is difficult for that object to escape from that bend
Any heavenly body having greater density then its escape velocity will also be greater
Dear friends! Escape velocity is the velocity
due to which any body can escape from the gravitational for of that heavenly body
Suppose that you want to escape from the gravitational force of the Earth then you
have to achieve 11km/s. Which is the escape velocity of the Earth.
we can find the escape velocity of any object using this equation.
Dear Friends
Any object having greater density must have higher escape velocity
There will be a certain amount of density for which escape velocity approaches the speed of light
this is the reason why light can not escape from black holes.
Dear friends! then question arises that how researchers have done their research on black holes?
When they can't even see the black holes.
Dear friends! answer to that question is that
