QUANTUM ENTANGLEMENT
The prediction of Quantum mechanics are weird which is against Einstein's relativity theory. According to Einstein, everything in the universe is absolute whether we observe it or not. But quantum mechanics says that nothing in this universe is absolute unless we observe it or measure it. In order to disprove the principles of quantum mechanics, Einstein along with his colleagues Podolsky and Rosen performed a thought experiment called EPR paradox. But their experiment gave birth to a unique phenomenon called Quantum Entanglement. To understand Quantum Entanglement, let us consider an energetic particle photon. This photon is converted to mass by using Einstein's mass energy equivalence. Since charge of a photon particle is zero, if we remove an electron from the photon, another particle positron is formed whose charge is opposite to that of an electron as the total charge of the photon is zero. So, here we can call the electron and positron to be entangled particles
