How will humanity first discover ET Life? Best guess: Technosignatures  Quite plausibly the reason we haven’t yet picked up ET signals is that we have not developed the necessary technology. How can we make progress? We need to better understand the foundations of physics. If there is any way to send information faster than the speed of light, that’s what advanced civilizations are using. Too many physicists currently believe that Einstein has proved superluminal signaling is impossible or that, if it was possible, it would somehow wreck the universe. Both are incorrect. There is no particular reason why faster than light signaling should be impossible. But if we believe it is impossible, we’re not going to find those aliens. Indeed, I am afraid the belief that the speed of light is an absolute limit is the biggest mistake in human history, ever.
