Quantum entanglement

     Quantum mechanics is not a completely understood theory as per scientific standards. There are some paradoxes yet to be accounted for. One of them was quantum entanglement. "When two particles say for example an electron pair when separated after being together, continue to remain entangled even after the separation of them by a large distances". It is like you and your roommate friend are separated from each other after being together for a long time, say by a distance of 100 kilometers, so sitting in your room, when you raise your left hand, your partner raises his right hand. But the question is how can a information travel faster than speed of light which was a big mystery? But later when we visit Einsteins legendary theory of relativity we find that nothing can go faster than speed of light.
         To make it still more clearer let us take an thought example of a photon(massless light particle) which travels at the speed of light and split each photon particle into two sub-photons using a technique called polarization in lab. Now if we retain a part of photon and send other part of photon to any end of universe and turn clockwise the photon which you have then the other part of photon instantaneously would spin in anticlockwise direction. And the question is: How did a tiny photon communicate to it's partner located at far end of universe within no time?
         Hence Einstein used to called it as a " Spooky action". There is enough proof for one of the stranger phenomenon of quantum entanglement within scientific labs but there is no rationally endorsed theory to support it...
          Quantum entanglement experiment was also carried out biologically on migratory birds. Quantum entanglement helps some migratory birds to navigate their way from one corner of the constituent to another, flying to and from distances of 13,000km or more. It is generally believed that migratory birds have an in-built compass that is based on measuring the angle between the Earth's magnetic field lines and surface of earth which helps them to navigate. And in experiment when birds were blindfolded, they were unable to navigate, despite the presence of magnetic field.
              According to the physicist Thorsten Ritz, a bird's eye has a type of molecule that has two electrons which are entangled. As we have seen earlier that two parts of electrons spin in opposite directions, resulting in overall zero spin. So if magnetic field is inclined, the difference in the chemical reactions in molecule, is translated into neurological impulses, hence produces map into birds brain.

    Judwa2 movie is a classic case of quantum entanglement then 😆

Time

            Since time is a hot topic today that runs across many theories in physics such as Newton's classi cal phy sics ,Quantum Mechanics, Relati vity, String theory etc, is the concept of time.          Time is used to define the speed of a moving objects in a classical sense and measure the gap between the two events. In the classical world , time always moves forward, and they are absolute, that is time is same for everyone. We all age with time and it is a witness to our ageing.       But in relativity physics time is not independent. Time is always related to space-time. Your time is determined based on where are you in space time. And time depends on your speed. Hence time ticks slow as you move faster. Finally when you reach the speed of light, time freezes. Assume that you have a time machine that could take you on a  space ride at the speed of light for 20 years and bring back home. When you meet your friends they would have  aged 20 years while you would still be

String theory

                    General relativity Gen eral relativity theory tells us about how the gravity works in the macro-universe. It mainly tells us how the planets orbit stars and how these stars and planets orbit the Galaxy and so on.                   Qua ntum Mechanics Quan tum Mechanics tells us about the mi cro-universe. It gives us descr iption of atoms, electrons and other sub-atomic particles and how they all interact with each other.                    Sci entists were trying to merge these two theories for a long time to make it is a unified theory due to some problems where these two theories don't agree with each other in principle. For example if we take black holes , which are extremely dense and are tiny forming singularity. So  which theory could be used to define among both the theories. Because relativity theory explains the extreme mass of black hole and quantum mechanics explains the singularity of black hole.         String theory says that the basic cons

Antimatter

In 1928, Paul Dirac , a British physicist found an equation which could have two solutions, one for an electron with positive energy and another electron with an negative energy. But according to classical physics the energy of a particle must always be a positive number.         Dirac actually meant was that for every particle in nature there should exist an antiparticle or antimatter. As just we can find an real proof example in case of equation x²=4, which has two solutions +2 and -2. Same way for every matter there should exist antimatter. Matter and antimatter are exactly same having same mass but with opposite spin. As such case of electron a negative charged particle there should be a positive charged electron ie., antielectron (positron).           But when matter and antimatter come in contact produces an tremendous amount of energy in the form of gamma rays. It means that when they both come to contact due to oppositely charged, they both gets disappeared giving out treme
