I recently watched a Ted Talk by Harald Hass. He demonstrated the technology of Li-Fi (Light Fidelity). In short, it is the use of the visible light part of the electromagnetic spectrum to transmit data. Technology such as Wi-Fi uses the radio wave part of the electromagnetic spectrum. Li-Fi has a far, far greater data capacity than Wi-Fi.
In a way, astronomy utilizes a type of “Light Communication” already. Stars communicate their composition by emitting a certain spectrum of light. Astronomers then decode the light to determine what elements are present.
Some theorize that light travels at different speeds when in different mediums and perhaps in interstellar space. What if the speed of light moves a great deal faster between star systems?
Stars could communicate, or be a part of a communication network, in Li-Fi. Not to mention that stars also emit radio waves (Wi-Fi), ultraviolet waves etc. Quite a large spectrum.
And to go further out on a limb; what if stars are the equivalent of neurons or have the capacity for thought themselves? If the thoughts of these thinking beings move slower, at a different time rate than ours…. the time spans that it takes to receive information from star to star, may not seem long.
