Black Holes - Introduction

Black Holes

    Black Hole can be defined as a region in space time  where gravity is so strong that nothing-no particles or electromagnetic radiation such as light can escape from it. Every black hole has a boundary which is known as the event horizon from which nothing can escape. As it does not reflect any light it is referred to as black body. It absorbs mass around it and grows, it can also merge with other black holes to form a supermassive black hole. Black holes are found at the center of many galaxies including ours whose size is bigger than our solar system and has a mass of about 4 million times that of our sun. Inside the event horizon of black hole is where physics would go nuts.

     Black holes are formed when the center of a very massive star collapses in upon itself. This collapse also causes a supernova or an exploding star, that blasts part of the star into space. After absorbing mass for some billions of years it would evaporate which is the end of its life. 

How are Black Holes detected?

Black Holes are detected by something known as 'Hawking Radiation', which basically is a black-body radiation that is predicted to be released by black holes, due to quantum effects near event horizon. Now due to such continuous emission of radiation it cause loss of mass and rotational energy which is known as 'black hole evaporation'.

Now the above things is what science says, So What is actually inside the black hole, what if we enter it, would it be turbulent as hell or pitch black. Till present no one has ever gone inside a black hole so it's difficult to predict but as it has enough gravitational pull that not even light can escape so it's obvious that when one enters the blach hole their speed is going to be much more than the speed of light. So there is a possibility that the human body could not survive such force and also our mass would become infinite as we achieve speed of light.

      

 If mankind somewhere in the future manages to develop spaceships which can withhold the force it would unlock a whole new chapter of research in science. If traveling through black hole is enabled then it would be a mere question of what is there on the other side of it. No missions are conducted till the present date physically to study the black hole, but efforts are being made to discover the unknown.
