Bull***. Newtonian theory gets the motion of mercury wrong. It is based on a false concept of space and time. On a practical level, if GPS did not make the relativistic corrections our bombs would not fall on target.

A primary

theory of gravitation. You may think of Newton as truncated after the second term. Einstein has a third term. It provides the extra 'Ompf' to solve Mercury's Advance.


THe gravitational potential is NOT a scalar. Strike one against Newton. It is not an instantenous interaction between masses. Strike two against Newton. Look at Newton's law. Do you see a retardation term there. You do not. Newtonian space and time is neither locally nor or globally Lorentz Invariant. Strike three.

You are confusing the fact that a linear approximation to the Einstein field equations works in a weak field with the fact that the theories are nothing like each.

It is 43 seconds per century different from

the Newtonian solution. Einstein solved the equations and published it. He did not dissent . I have Robin M Green's "Sperical Astronomy" and he shows that the two methods are complementary -- not mutually exclusive. and if you are calculating planetary orbits, a Newtonian solution is very, very, very close. yes there are corrections, but to


Without General THeory the GPS fails disastrously. That is not "close".

locate a planet you only need light time correction.


No no. You need the metric tensor clean through the entire cosmos. Read -The Physical Foundations of General Relativity- by D.W.Sciama to see why one cannot cobble an interaction that looks like electromagnetic interaction.

This is not true. I know how they realate. for instance in relativity calculations the time is a system of labels. yes, they are different but they have identical syntatical untis. all of the equtions of state for orbital motion have exact analogues in relativistic calculations. the essential solution of the equtations is the same. you have 6 constants of state and 10 equations. it remains a problem. and the problem of Mercury was defined by Newtonian methods. the solution only confirms the Newtonian. it does NOT refute it. that is a creationist idea.

basically, calculus is calculus. the solutions are different of course. but you confuse cosmology with celestial mechanics


"only". I love it. By the way there is no tensor formulation of gravitiation that looks like the electromagnetic stress momentum tensor for electrodynamics. So you can't get a "maxwellian" theory of gravitation. Close but no cigar. The only reason it is close is because the Sun produces a a weak gravitational field.

Conceptually and mathematically General Theory is totally different from what Newton postulated. The conception of space-time is totally at odds with absolute space and absolute time which is the basis of Newtonian physics. Newton assumed instantenous interactions. He made no essential use of the finite speed of light, even though he was familiar with Roemer's estimates of light speed.

actually, you dont really appreciate how Newton did it. He was a remarkable mathematician. He LOVED to calculate. The essential solution of two body uses newtons prublished method. His investigation of light were much more primative. he proposed that light was only a wave. He did invent the reflecting telescope. He solved cetain problems in optics. He was good at solutions. I will note that his principia is about motion and realted problems. He defined gravity as a force. we know that force is true. r'' = G (M+m)/r^2

there is a story about Newton as an old man. They had a problem where there were two points one high, on low, they were offset slightly. now calculate the fastest curve between those points. A prize of 100000 pounds was offered. Newton posted a solution anonymously.

the people judging the entries, "Recognized the Lion by his Claw." this problem appears in most of the Calculus texts I have. it is a problem in variable parameters.

In science theories change. Newtonian physics was always limited in solving physics problmes.

you may know the words but you dont seem to understand the mathematics.

show me YOUR world line.



Maxwell provided that proof. Maxwell was before Einstein.
so was Lorenz who created the Lorenz Contraction. It was a solution to the problem indicate by Michaelson and Morely.
Einstein had to INCLUDE all this physics. and he was working on the essential problems. his first paper was on brownian motion. his second was on the photoelectric effect. to understand what Einstein did was formulate a solution. his famous equation in realtivity E=MC^2, is the solution to an energy problem in quantum mechanics. To say that Einsten was refuting Newtownian Physics is not true. That newtonian method is used commonly to calculate orbits. it is not used in quantum mechinics.

There is currently NO CONSISTENT THEORY of GRAVITY. A singularity is division by ZERO. it is breaks most theories.
I know a lot about what is known about the inside of a blackhole. You imply that you know a world line. show me the metric. and tell me what kind it is.
