Finally someone on YouTube stated the exact reason for the precession! Which was the time dilation from the difference in the gravity along the orbit. Thank you.

[curtischee]

I really like how you geometrically describe the precession by connecting the perihelion with the aphelion. You show exactly what the 574 arc seconds is measuring. You are the only resource that explained exactly what is going on geometrically. Great visual explanation. Thank you so much.

[cyberfunk]

The fact that they could make such accurate measurements already back then to me is almost as impressive as the prediction made by GR. If I had to guess before seeing this video, I would never have guessed the measurements were so good already then.

Amazing. Many thanks for sharing science and maths. Big respect from U.K.

The paper where is described the solution for the precession of Mercury’s perihelion, but like the precession of a gyroscope (derived from the Lagrangian mechanics and the General Theory of Relativity) is the following (from 2014):

[adurgh]

Does precession happen in the same plane of the orbit?

[imsmoother]

Nice explanation. Would it be possible to give a general explanation for the derivation of the formula?

[mireksoja]

Thank you. It’s great explanation! I like he voice commenting from the inside the room.

SIR, DOES THAT FORMULA HAVE ANYTHING TO DO WITH EINSTEIN FIELD EQUATIONS
AND IT WOULD BE GREAT IF YOU MAKE A VIDEO OF EINSTEIN FIELD EQUATIONS AND SOLUTIONS OF IT AND RESULT WE OBTAINED FROM IT.

Hmmm... These numbers appear to be approximations. Only 2 decimal places are used for Mercury's orbital period. l would like to see the values using 100 decimal places for Mercury's orbital period.

From what I understand, gravity is curvature of space-time. That means 574 is caused by curvature of space-time. Einstein applied his theory by taking into account only the Sun and Mercury, and found 43. How come the other planets have more influence (531) than the Sun (43) on the orbit of Mercury?

[trevor]

Sir, is this equation applicable for all planets or just for Mercury?

[rqxnpdv]

First I like the video, then only I will watch the video😊

[ericsu]

There is an error in Albert Einstein's paper about Mercury. Two roots of one equation are imaginary numbers which Einstein used to calculate precession.

[ericsu]

The theory of general relativity is invalid because it predicts the angular difference between the aphelion and the perihelion to be 2 radian for the orbit of Mercury. The actual observation is about 6.28 radian. More in

Many theories predict that. It is just twice the Newtonian value. You could have told people that, but then they would be less impressed.

[mhdabb]

I suppose to wait another 200 years to final check

Wrong it is not "sec", but "s".
