Ok, thanks. @phinds, @TensorCalculus ans @PeroK. I appreciate to be guided. And also your feedback that I need to listen better.

Thanks for visualizing my formula and letting me know about desmos.

Ok, ok. You’re right that Newtonian gravity and the weak-field approximation in general relativity aren’t the same—and I appreciate the clarification. I fully acknowledge that Newtonian gravity doesn’t handle light correctly—since it assumes particles with mass and low velocities.

Thanks a lot for a constructive feedback. The formula with E=pc^2 + mc^2 made my day. Its intuitive and replaces my understanding that "photons" / light signals had some kind of mass. Photons to me is energy packets with light speed and frequency. According to the formula they transport...

Cool formula, I think in terms of energy preservation. Whether it is frequency, mass, potential or kinetic energy. Vibrations, temperature, electric energy and so on. Nature know nothing about straight lines in that sense, and modeling it with coordinate systems that make curved straight is of...

Yes, thanks for mentioning that, GM/r is way off at r close to 0.

The formulas I have used are for weak field approximations. The thread is also tagged with gravity and newton. So, while special and general relativity is another liga, the weak field approximation predicts well enough for the bending of light near our own sun.

I wanted to test if I could use the density formula all the way to infinity, without switching to the mass formula, and it worked. That was cool.

I find what I say in my article educating. Maybe someone else will also? Maybe I posted it in the wrong forum? Or maybe I should post it as a lower level.

Wow, ok, so I am a dummy then? I was allowed to register and post. And you are allowed to use your expert knowledge to guide me if I am off.

Ok, I am looking at the general and special relativity formulas now.

This model describes the gravitational field of a non-rotating, spherically symmetric body—without spin effects such as centrifugal acceleration or equatorial bulging. The Construction Process • Begin with Newton’s law of universal gravitation and a sphere of radius R with constant density d. •...

You are right. But it still bends in a gravity field. And a photon has both particle and wave properties. So, that it bends could be because both mass and frequency is energy. In my intuition, this makes some sense, with my limited understanding. I know that with Einstein its about finding...

Col Ok, for a photon, v=c, so I was thinking this was valid. Bending of light happens at light speed

So, the formula for the bending of light in general relativity is: phi = 4GM / (rc²) So that is the one I am using. Execpt some syntactic sugar where other letters are used, meaning the same. r vs b So, then I can use math to adjust this formula. phi = (4GM) / (rc²) multiply by 1 ->...
