What do you mean by predict and why would it be worthless? They can already predict how things act and react under mavity
Well that's why it's a scientific theory.
Newton's theory of gravitation makes predictions... some of which were found to work very well (orbits of most planets, how things fall, etc) and some of which weren't found to work very well (orbital deviations of certain planets).
Einstein's theory of general relativity makes predictions again - it accurately predicts the orbits of all the planets (much better than Newton), aswell as predicting gravitational lensing and the occurrence of singularities (black holes)...
Yours doesn't predict anything - it's not scientific. It's as scientific as believing the world exists on the back of a giant tortoise. It's just a random idea plucked from nowhere with a few buzzwords strung together to make it sound nice.
