Hi,<\/span><\/p>\n

Welcome to my page. To introduce myself, I am a theoretical physicist working in the interface of quantum gravity and quantum cosmology. To give a glimpse of it, gravity is the most dominant force in the universe at large scale but the one that is least understood. Around three hundred fifty years ago seeing an apple fall before him, Newton proposed the universal law of gravitation. This states that the law that makes the apple fall on the surface\u00a0<\/span>of the earth is same as the law that governs the motion of the moon, earth and all celestial bodies. This was big leap of thought at that time. It was a statement of unification and “symmetry” in nature. And around hundred years ago Einstein showed that gravity arises as a result of general covariance, a symmetry statement indeed which we know today as General Theory of Relativity.<\/span><\/span><\/p>\n

The story does not end there. A school of thought says that gravity, on its own right, must be quantized like other three fundamental forces. In essence, the underlying symmetries of general relativity must find its quantum analogue. And loop quantum gravity (LQG) is a tentative candidate to find the quantum analogue of Riemannian space in Dirac sense.<\/span><\/p>\n

Using the framework of LQG, I work on the symmetry reduced quantum corrected dynamics of spacetime as applied to early universe, generally called loop quantum cosmology. One of the astounding results of these models is the resolution of singularity. To say it in a more creative way…perhaps,\u00a0 the “apple” doesn’t “fall” at the minuscule scale.<\/span><\/p>\n
