They&amp;#x27;ll even reflect moonlight.&lt;p&gt;From the linked piece from Curtin Uni:&lt;p&gt;&lt;pre&gt;&lt;code&gt;    We estimate emissions in radio wavelengths will need to be reduced by a factor of a thousand or more to avoid significant interference with radio astronomy. We hope these improvements can be made, in order to preserve humanity’s future view of the universe, the fundamental discoveries we will make, and the future society-changing technologies (like wifi) that will emerge from those discoveries.&lt;/code&gt;&lt;/pre&gt;</text></comment>

Fifteen minutes later they&amp;#x27;re completely invisible.</text></comment>
