Testing SR with a Rotating Mass: Experiments & Theory

AI Thread Summary
The discussion explores the theoretical implications of accelerating a high-density mass to near light speed and its effects on gravitational fields and light. It posits that as the mass approaches light speed, its relativistic mass increases, potentially bending laser light emitted from above it due to the enhanced gravitational field. The conversation touches on the relationship between energy, mass, and gravity, referencing key equations from relativity and gravitational theory. Concerns are raised about the compatibility of these ideas with Lorentz invariance, which prohibits assigning mass to photons without violating fundamental principles. Overall, the thread delves into complex interactions between mass, energy, and gravity in a relativistic context.

What if someone set up an experiment, where they sped up a mass of high density in a circle ethier by making its radius smaller and smaller, until the large mass is moving near the speed of light, then at an extremely small highet above this rotating mass you set off a high frequency laser light, theorticly shouldn't the mass of the moving object increase, because of SR, thus having a larger gravitational field, and then the grav field should bend the laser light. It is most likely such a small divergence that it is unmeasureable but wouldn't we expect to see this? According to the force eqaution..

E = mc^2 = hf \ F = \frac{G m_1 m_2}{r^2}
m = hf/c^2 the grav force is acting on the "mass" of the light
F = \frac{G m_1 hf}{r^2c^2} \ m' = \frac{m_0}{\sqrt{1 - \frac{v^2}{c^2}}}
F(m_o,v,f,r) = \frac{Gh}{c^2} \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}} \frac{f}{r^2}

which can of course broken into a relation of v to the rotational frequencey of the mass. Also as is my understanding that a grav field effects clocks, so that in this synethic grav field that anything moving through it would have its relative time slow down. ie see everyone else moving slower then they are.

am I to assume that all of this seems sound? and that this Force should be expected
 
You cannot plug in a mass value for photons this way without breaking Lorentz invariance. Experimental tests have constrained Lorentz invariance violations to no more than one part in 10E20.

what is Lorentz invariance?
 
i believe u find the Schwarzschild Radius by stating that the "mass" of a photon is hf/c^2 so that a grav field acts on anything with energy.

U = \frac{G m_1 m_2}{r} \ m_2 = \frac{hf}{c^2}
\frac{1}{2} m v^2 = \frac{G m hf}{rc^2}
\frac{hf}{c^2} v^2 = \frac{2 G m hf}{rc^2} \ v = c
c^2 = \frac{2 G m}{r} \ r = \frac{2Gm}{c^2} <- Schwarzschild Radius
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
