                The theory of relativity T he most famous scientist in the history.  Prof albert einstein, who is always associated with the most interesting, strange, mind blowing theory that show us the most strange behaviour of time and space. The theory of relativity. The theory is divided into 2 parts 1. General relativity 2. Special relativity. General relativity This tells us that there is no absolute rest or motion. As a person is standing near u is rest for u but as earth is moving and galaxy is also moving hence u are not at rest Special relativity This is quiet interesting.  It has some constant. This tells us that speed of light~3*10^8m/s is constant for everyone.  Whenu travel near speed of light (99%) speed of light will not be 3000km/s for u but 3*10^8m/s only. This arises a question that does 3rd person also observes it 3*10^8m/s? The thing that happens is dilation of time. Yes this sounds some strange...

                        Virtual particles In quantum physics there are many particles like electron,  proton,  neutron, quarks, muons , mesons, bosons, photons etc. but there is a special kind of particle known as virtual particle. These particle are the strangest particles ever discovered. As per to quantum physics the space is made up of a quantum field in which 1 cubic metre of empty space contains a mass of about 4 protons. This mass is responsible for generation of this particles The most special thing about it is the particles form anywhere in the space in a pair.  The life of this particles is fraction of the second.  The particles forms and dissappear. The particles formed are having same mass but one in negative and other in positive.  For instance 1 particle is having mass of 1 kg then other will have mass of -1kg (this is just e.g actual mass is very very small) If talk about space...

                          Black Hole There are some phenomenon in universe which shows the unthinkable possibility of nature. One of the most strange phenomenon is black hole .     As name suggests ,  they are black but not a hole on a contrary just a sphere in space with infinite gravitational intensity and infinite density (No volume just mass)  As per relativity the black hole generates infinite curvature of space time If talk about structure of black hole it has a radius of millions of km. The boundry is known as event horizon inside which no light is present.  The outer environment when it is near a star generates assertion disc (billions of km in radius) which is made up of gas. The thing that makes black hole a crazy and interesting subject is the phenomenon that occurs.  The most strangest phenomenon is dilation of time.  Hypothetically If we are at event horizon for abou...

                           Gravity Gravity is one of the 4 fundamental forces of universe that knows just to attract other matter towards itself . As per myth an apple fell ob Newton (story was false ). In reality he got the idea much before.  Newton is associated with gravity and just found the effect of it, but could not find the mechanism. In late 20th century a new theory was found of gravitation.  As per which the quantum of gravitation ends at a small subatomic particle with 0 reat mass. This particle is known as graviton. The exchange of graviton is a hot reason or mechanism which bring gravitation gravity in existence There is a big misconception that gravity is due to the curvature of space time fabric. The space time curvature is just responsible for the density and intensity of gravitation of a particle e. g The curvature of space time of black hole is infinite the, this tells us the is i...
