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.

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 ...

This mathematical framework allowed Einstein to describe curved spacetime and express physical laws in different coordinate systems. Tensor Calculus: Einstein adopted and expanded upon the tensor ...

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 ...
