I want to write a sci-fi short story, and want to use a possible method of superluminal communication (Communicating with someone faster then light)
I am no scientist and literally just searched "Science Forum" so feel free to correct me. Here i go.
A personal theory that i could not find anywhere else on the internet was using gravity. Let me explain
If you could change the amount of gravity quickly in you're location then someone many light years away would instantly be effected by that gravity.
So if the dude light years away could bounce a laser of a planet and very accurately measure difference of planet orbit because of gravity far away one could communicate effectively
faster than light...
If that is a bit confusing i tried to make a plan trough a picture attached to this thread.
Or maybe there is some newton law that ruins everything, That dude is always messing up my cool sci-fi stories!
