Hi forum, the search for ET is largely (entirely?) focused on looking for electromagnetic signals, correct?  What if advanced races discovered a better (think faster…than light) way to transmit signals.   Obviously we are not looking for whatever that is but I think the Drake Equation should factor it in.  If the vacuum of space is teaming with advanced ET signals but we are only looking for 1 type of signal (electromagnetic waves) we may never connect.
