Stellar Evolution after the Main Sequence
... According to Newton, it acts instantaneously so that for each 'update' of positions, the force changes and can act on the masses immediately. But, according to Special Relativity, nothing can move faster than the speed of light – so nothing is instantaneous "What we have here is a failure to communi ...

Intro to Cosmology!
... Superpartners exist in separate quantum Space-Time coordinates called “Superspace.” The existence of a superspace simplifies QFT significantly. General Relativity can be derived from the theory of Supersymmetry. Predicts the energy level of electroweak recombination to great accuracy. ...
