Why did Newtons theory of gravity differ from Einsteins and why was Newton wrong?
Newton’s and Einstein’s are BOTH wrong for the simple reason that they’re not "Mathematically" proven as is the Truth of – EXPANSION ACCELERATION.
Newton’s law of gravity is very accurate for predicting motion… but not the full story. Einstein described the space-time fabric. Masses in space deform the fabric. It is the result of this warped space-time that gravity exists. Objects travel the shortest distance through the warped space-time. Hence, the earth does not orbit the sun because the sun is attracting it (what Newton said). Instead, the earth is simply following the shortest path. It’s kind of hard to write in words. You really need to use diagrams.
