Gravitational big date-dilation accompanies curve since the methods of your time are based on action, and contraction regarding point means swinging clock parts (and additionally such things as oscillating electrons, oscillating quartz crystal atoms, etc) travel a smaller range in confirmed date, and also make date apparently impede
Feynman said that the contraction from place around a static bulk Yards due to curve as a whole relativity try a reduction in radius of the (1/3)MG/c 2 that is step 1.5 mm into the Environment. (Baez and you may Bunn also has actually an excellent derivation out-of Newton’s laws out of general relativity, that does not fool around with tensor analysis: get a hold of We are able to get it done just using the fresh equivalence concept from standard relativity and a few physical sense:
