Quantum Field Theory (QFT) in curved spacetime is a fascinating area of theoretical physics that combines principles from quantum mechanics and general relativity. This field studies how quantum ...

It may sound complicated, but it can be assumed that there is a mathematical transformation that allows us to describe curved space-time equivalently as flat space-time where certain forces act.

To express his ideas mathematically, Einstein needed new math : Riemannian Geometry: In 1912, Einstein’s friend Marcel Grossmann introduced him to Riemannian geometry and tensor analysis. This ...

But Einstein’s theory states that there is no force of gravity, it’s just the effect of our planet as it freely falls through curved space-time around the Sun. Below is a 2D representation of ...

AdS stands for Anti-de-Sitter, a special type of spacetime that is curved inward, like a hyperbola. CFT stands for conformal field theory, which describes quantum physical systems whose properties ...
