Dedicated to my friend Thirumurthy who asked a question on Tripura Rahasya and hence I wrote this  Quantum physics  says that our vacuum is filled with vibrations (Rudra) of Energy (Shiva).  These vibrations can exist at a high energy level  for a moment and be at a very low level another moment violating law of conservation of energy.  At specific energy levels, these vibrations  can manifest particle pairs (quarks, antiquarks, leptons/anti-leptons) which the Universe is made of.  Quantum physics says things can get created and destroyed without a cause.  It says a specific ‘cause’ may not preceed an effect or every effect may not have a cause (it could be probabilistic, random). There need not be any harmony in the Universe. For eg. a Higgs vacuum decay can destroy Universe for no reason, far beyond us. In Tripura Rahasya,  Dattatreya says “ Carvakas  say that some effects are not traceable to their efficient causes. There are...

Background The cosmological constant problem As different fields of studies like Cosmology (involving gravitation and relativity theories), Quantum Electro dynamics (QED), Quantum Field Theory (QFT) emerged in their own ways, their contribution to each others also started emerging. A case in point was cosmological constant. Einstein devised the cosmological constant (whose units are cm -2 ) from a cosmology (Gravitation and Relativity) perspective to balance the curvature of space and define a static universe. Einstein abandoned the concept after Hubble 's 1929 discovery that all galaxies outside the Local Group (the group that contains the Milky Way Galaxy) are moving away from each other, implying an overall expanding universe. From 1929 until the early 1990s, most cosmology researchers assumed the cosmological constant to be zero. Since the 1990s, several developments in observational cosmology, especially the discovery of the accelerating universe from dis...
