-
Owe Kristiansen replied to the thread I Reframing Light Bending Using Density Instead of Radius.The formulas I have used are for weak field approximations. The thread is also tagged with gravity and newton. So, while special and... -
Owe Kristiansen replied to the thread I A "continous" gravitational field formula r=0 to infinity.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...

Owe Kristiansen reacted to Baluncore's post in the thread I A "continous" gravitational field formula r=0 to infinity with
Like.
It is easy to know which equation to apply, so I see no need to merge the two equations. The internal gravity model, that integrates... -
Owe Kristiansen replied to the thread I A "continous" gravitational field formula r=0 to infinity.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...

Owe Kristiansen replied to the thread Hi.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.

Owe Kristiansen reacted to PeroK's post in the thread I Reframing Light Bending Using Density Instead of Radius with Like.
That's only an approximation (for small ##GM/rc^2##). Note that in some cases, Newtonian gravity is a close approximation to GR -...

Owe Kristiansen replied to the thread I Reframing Light Bending Using Density Instead of Radius.Ok, I am looking at the general and special relativity formulas now.

Owe Kristiansen posted the thread I A "continous" gravitational field formula r=0 to infinity in Classical Physics.This model describes the gravitational field of a non-rotating, spherically symmetric body—without spin effects such as centrifugal...

Owe Kristiansen reacted to Dale's post in the thread I Intuitive look at bending of light by gravity with Like.
For a pulse of light ##m=0##.

Owe Kristiansen replied to the thread I Intuitive look at bending of light by gravity.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...

Owe Kristiansen replied to the thread I Intuitive look at bending of light by gravity.Col Ok, for a photon, v=c, so I was thinking this was valid. Bending of light happens at light speed

Owe Kristiansen reacted to Hornbein's post in the thread I Intuitive look at bending of light by gravity with Like.
I'm sure Albert was glad of that factor of 2 difference. Imagine how disappointing it would have been if the result had been exactly...
-
Owe Kristiansen replied to the thread I Reframing Light Bending Using Density Instead of Radius.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...

Owe Kristiansen replied to the thread Hi.I guess my intuition is not always good, but at the core, I want to understand, not just accept. I am not good at memorizing formulas...
