There are only 2 types of electromagnetic radiations that matter can emit:- Due to a chemical reaction (includes nuclear radiation) Due to accelerating charges Radiation due to changing current (accelerating charges wrt. their current...

Why Relativity And Quantum Mechanics Can’t Be Friends?

Introduction General theory of relativity (GTR) describes gravity as a geometric property of space-time fabric.  It combines specific relativity and Newton’s law of gravitation. GTR which accounts for gravity and all of the things it dominates: orbiting planets, colliding galaxies, colliding black holes, formation of planets etcetera. Easiest definition of what gravity is that, it is an attractive force between...
