Welcome to Philipp's Online Astronomy Journal.
I am a professor of electrical engineering at Syracuse University and my main research activity is developing specialty optical fibers which we fabricate. We make optical fibers with various material layers between the glass core and glass cladding. Applications are strain sensors, bio fluid sensors, broad band light amplification including fiber light amplifier plates for image amplification in 3 D and full color.
However, I am interested in the effect on the motion doe to the delay in the gravitational interactions of stellar bodies.
I am interested in the effect on the motion of stellar bodies doe to the delay in the gravitational interactions between stellar bodies. For example
if a sudden gravitational shift were to occur in the sun we would sense
it about 8 minutes 19 seconds later. I did some calculations and got
interesting results. Since the interaction delay time in the solar
system is small compared to the duration of an orbit the effects are
very small. But they add up over time periods of billions of years.
Caution: in the calculation of delayed interactios both the advanced and retarded terms have to be used. If only one of the terms is used, as was done by a vey prominent astronomer, unrealistically large efects are calculated.
Please supply me with data to try in may calculations.

Comments about where I live
Well, it snows a lot. Actually it snows more than that. We can get 4 m of snow per year.
It is cloudy a good portion of the year.
