But as he writes in the paper, any entangled communication among stars “can be rendered in principle indiscernible to those of us excluded from the conversation.”</em></span></span></p><p> </p><p><span class="font-size-3"><span style="font-family:georgia, palatino;"><em>So if there were a mega-advanced civilization out there colonizing the Milky Way galaxy, communication along the lines of what Rudolph has proposed could explain why we haven’t found any evidence of life beyond Earth.</em></span></span></p><p> </p><p><span class="font-size-3"><span style="font-family:georgia, palatino;"><a href="https://futurism.com/the-byte/aliens-communicating-starlight" target="_blank">Scientists Claim That Aliens May Be Communicating Via Starlight</a>, Dan Robitzski, Futurism</span></span></p><p></p></div>
