Is earth surrounded by a Dyson sphere?

I've heard of Dyson spheres used as a form of energy capture
But what about a similar structure to transmit information about the host civilization to the rest of the galaxy (through the selective dimming of the stars light with certain intervals)
Like the gold disk from the Voyager mission , only with a far better chance of being found?
Would it be feasible?
How much information could it transmit?

Let me introduce you to a new concept:

You need material to have, to be in work, to make a work, you need energy to do that.

Problem: Dyson sphere is inefficient use of material to obtain energy, as there is not so much material in star systems, to do a construction like this, to have some "effective" body movement from it.

On every image on dyson sphere, there is just one big thing, collecting energy.

Advanced civilisations won't use dyson sphere, but they'll have energy from balance, e.g. energy will be recycled, heat will be "organized" into non-brownian motion of huge bodies, electron potential of surrounding space will be pointed to a place where it will do usefull work.

Dyson sphere is not advanced at all, it obeys to law that closed systems can't absorb energy, problem is that you don't live in closed space.

Potential energy can flow in closed loop... More like "electrons don't dissapear" and you make them constantly moving trought working "part" of thing. e.g. electrons on matter in isolated space are constantly pushed to do some work, then they emit heat in the resistor. Resistor decreases their potential energy, but they're not lost. They can move in loop forever powered by the fact that out of electron properties you can costruct device that'll just direct free radicals(resistance, transformed energy) again to do some work, e.g. propulsion.

Dyson sphare could be only usefull if you made components out of that stuff sun emmits in the universe. It doesn't make sense for energy device to be that big and using so much material.

Is it aliens, /sci/?

any astronomer's on /sci/?

i'm doing research on boyajian's star at caltech.

let's talk astronomy.
