Could Bell experiments reveal a link between photon spin and gravity waves?

[kurious]

When a photon's spin is measured, the photon must exert a force on the device that measures its spin.Since a force is associated with an acceleration and an acceleration with gravity,could the photon have created a gravity wave that travels through space and determines the spin of a second photon coupled to it?

It would appear that this model would show a link between gravitons and entanglement. If gravitons are at all what we think they are, they travel at lightspeed, so this link should eb impossible.

Then let the gravitational force carrier move faster than light.If it did then its wavelength would be greater than LIGO experimentalists expect and that could be why they haven't detected any gravitational waves so far.

i don't think the speed of gravity waves would matter to a detector would it? there are a lot better reasons why we haven't detected gravity waves besides...

 

[kurious]

The amplitude of a faster wave would be smaller- it would matter to LIGO detectors.

I would think that gravity waves travel at c or maybe a little less because if gravity waves travel faster than c then it would be possible to send information faster than the speed of light. Just have a device that reads the gravitational pull excerted by another object far away. Move the object accordingly and the detector can pick up its movement by changes in the gravitational pull exerted on it. But who knows.

 

[kurious]

The idea of information traveling faster than light is why I started thinking about gravity doing so.Gravity is still a poorly understood phenomenon and
every particle in the universe is associated with it and so could communicate quickly with it.

In 1993, the Nobel Prize in Physics was awarded to Russell Hulse and Joseph Taylor of Princeton University for their 1974 discovery of a pulsar, designated PSR1913+16, in a binary system, in orbit with another star around a common center of mass.

Using the Arecibo 305m antenna, Hulse and Taylor detected pulsed radio emission and thus identified the source as a pulsar, a rapidly rotating, highly magnetized neutron star. The neutron star rotates on its axis 17 times per second; thus the pulse period is 59 milliseconds.

After timing the radio pulses for some time, Hulse and Taylor noticed that there was a systematic variation in the arrival time of the pulses. Sometimes, the pulses were received a little sooner than expected; sometimes, later than expected. These variations changed in a smooth and repetitive manner, with a period of 7.75 hours. They realized that such behavior is predicted if the pulsar were in a binary orbit with another star.

Bell has nothing to do with gravity. You cannot derive any kind of link with gravity from Bell, period. Regardless of the nature of the hypothetical root of the 2 photons' spin, it cannot be local realistic. That is all Bell says.

QM separately says that photon spin is not tied to gravity. So you would have to come up with some pretty fancy footwork to create a theory that couples photon spin to gravity given the experimental evidence in support of QM.

Kurious:
Every particle in the universe exists in a gravitational field.
The Bell experiments take place in a gravitational field wherever they can be possibly done.There has to be a link!
And who said that the photon's spin would be affected by the spin of the graviton - the photon's spin might be affected by the energy of the graviton.
Also, given that LIGO has not detected gravity waves yet, there is hope that
it may have failed to do so because the waves have a speed greater than light and a smaller amplitude than expected.
