To know about hawking radiation, first you will need to have a basic idea about “Black Holes”. When a massive star dies, it leaves a dense remnant core. If the mass of that core is  3 times more than the mass of our own sun then the gravitational force overwhelms all the other forces and because of this a Black hole is formed. A black Hole isn’t just an empty space instead it is a space where a lot of things are packed into a very small area. Just think about it, A star that is 10 times bigger than our sun and then it being squeezed into a small area whose diameter maybe as small as a city ! The gravity in the black hole is so Strong that even light and X-rays cannot escape ! Until 1974 when Stephen Hawking put down the theory of Hawking Radiation, it was believed  that the black hole doesn’t emit or radiate any kind of energy. But this changed because of the Hawking radiation theory which was made by combining Quantum mechanics and Einstein’s general theory of relativity. Acc...

  Quantum Tunneling isn’t a law or a part of the physics we learn in our day to day life but it is part or we can say a theory of quantum Mechanics. First of all, let me tell you what is Quantum Mechanics, Quantum Mechanics means study of matter at atomic or sub-atomic levels. Quantum Mechanics is a theory which is very complex to understand and may seem crazy to a normal person   Now, let me tell you about Quantum Tunneling…… Quantum Tunneling allows us to go through or pass to a barrier obstructing us. It may be a physical substance, vacuum or a region of high potential energy. For example, According to physics the body needs to have enough energy to pass or travel from one point to another. But Quantum Mechanics says that the body can travel the distance even if the body doesn’t have enough energy to travel (As in classical mechanics).And in the case of Quantum Tunneling, we know that the matter is either wave or a particle and while Quantum Tunneling the wave force starts ...
