Falling into a BLACK HOLE !

" We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the universe . That makes us something very special. " ~ Stephen Hawking.

In his theory of general realativity Einstein predicted how black holes are formed when massive star dies and collapses it leaves a smaller remant core behind.

This core's mass is at least 3× bigger than the mass of our sun. A black hole , as it's name suggests is not a hole at all.It consists of huge amount of matter packed into a very small space.

When a particle enters a black hole, Space , Time , Laws of Physics are no longer aplicable. A black holes gravity is so strong that even light - the fastest entity in the universe can't escape it.

One can't see the black hole . Its invisible.

Stephen Hawking believed that black holes can be a passage to another universe.If you were to fall in one you would find yourself in an alternate demension.

However , its only possible if you succeed crossing its intense gravity . The Event horizon - the edge of the black hole is also an edge of the concept of Time  and Space . Event horizon is the point of no return . Basically , its the boundary of a black hole .

The moment you fall inside the Event horizon things won't be the same. Under the influence of extreme gravitational force you will get strecthed out. 

This is termed as Spagettification . You will actually turn into like a long , thin tube of pasta.And as our physical body will not be able to withstand it , we will eventually die.

But things are not same for a person who observes you falling into a black hole. For him you will get dimmer and fainter and finnaly apper freezed . No matter how long you watch, you can never see the object enter into the black hole. This is due to Time dialation. Time almost slows down and stops in the black hole .

Black hole pulls every thing to its center. The scientists call it Singularity. There the density is so great that the laws of Physics breaks down. In a nutshell , Singularity is the point of infinite Gravity where space and time becomes meaningless.

So , to conclude , there is no escape from black hole. No light of any kind , including x-rays , can escape from the Event horizon. NASA's telescopes that studies black holes are looking at the surrounding environment of the black hole, where there is material very close to the event horizon. Matter gets heated up to millions of degrees as it is pulled the black hole , so it glows in x-rays. The immense gravity of black holes also distorts space itself, so it is possible to see the influence of an invisible gravitational pull on stars and other objects.

This is the first ever image of black hole . Among the many other theories of Albert Einstein black holes , gravitational waves , gravitational lens and time time dialation are proved . While white holes and worm holes are still unproven.

The closest black hole to earth is in the centre of the Milky way , some 25,000 light years away ,its called Sagittarius A , it is a supermassive black hole .

A stellar-mass black hole , with a mass of 10 times that of the sun , can likely form in seconds , after the collapse of a massive star.These relatively small black holes can also be made through the merger of two dense stellar remnants called neutron stars. A neutron star can also merge with a black hole to form a super massive black hole, or two black holes can collide to form the same . Mergers like these can make black holes really quick , and produces ripples in space time called the gravitational waves.
