The Speed of Light is NOT About Light

c = speed of CAUSALITY!



Is that only for particles with mass, and massless waves, or does that all include information? (i.e. quantum entanglement)



Imagine two planets hundreds of light years apart, but exactly the same distance from a specific quasar, and they find a source of entangled radiation coming from said quasar, can they use that light source to communicate instantaneously across the light-years of space, by having a receiver choose to interact with the entangled source radiation in alternating patterns (such as binary code or Morris code)?
