Was Isaac Newton correct about his Gravitational Theory?

Answer 1

Yes, correct but not complete.

Newton's Theory of Gravity accounts for the so-called deflection of light by Einstein's General Relativity Theory.

The angle of deflection is Tan(angle)=s/R = .5gt2/R

where t=R/c= 500seconds where R=150Gm distance to the sun and g= 9.8 m/s2, earth's gravity. The Tangent (angle) = 8.16666E-6 seconds indicating the angle is 1.68 seconds.

Newton did not completely describe the Gravitational Energy. He described the Potential energy or real energy,

Er=-mGM/r = mu/r, however, he did not describe the vector energy Ev=cP=cmV, the momentum energy.

Thus the Total Gravitational Energy = -mGM/r + cmV = m[-u/r, cV]

Gravitational Energy is a Quaternion Energy and the vector energy cP is the so-called unknown "Dark Energy".
