Please critique my argument: We know(?) human radio sphere signals is distinguished by attenuation and drowning in background noise long before reaching any potential planets.   <br>Just think about it, we almost not able to detect our own space probes, only just outside the solar system, when we know where to find them, and only at a glacial 2.8KbPS datarate utilizing lots of bandwith for fault toleranse in the transmission. (If probes broadcasted at television/radio signal data rates, signal would just look like random noise to our listening-station. Higher data-rate = less range)<br>Also, arguments of Dyson spheres being visable depend on Dyson spheres being possible and/or worth the effort building, which there is no reason to think they are, and lots of reason to doubt. <br>What is wrong with my argument?
