How quickly do changes in fundamental forces propagate?

AI Thread Summary
Changes in fundamental forces, including gravity, propagate at the speed of light. If one object suddenly vanishes, the other would not feel the gravitational pull change instantly but rather after a delay proportional to their distance apart. In the case of two objects two light years apart, the effect would be felt two years later. This principle applies universally to all fundamental forces. Understanding this propagation speed is crucial in discussions about the nature of gravity and other forces.

If there are 2 objects at the distance of 2 light years from each other exerting a pull of gravity on each other and one of them vanishes suddenly would the other feel the force instantly or 2 years later or after more time

When you do a Google search for Speed of Gravity, what do you find? :smile:

Just for clarity, changes in fundamental forces travel at c.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
