If you stay within the realms of physics, there are no great choices. Electromagnetism is the easiest one, other waves or quantum based ideas are hard (physically speaking).
It is very probable that electromagnetic waves are what you start with.
- itishappy 2y agoNo arguments here! EM is my career. :) My point is that this limits our search somewhat to just interstellar species, and that's a crazy high bar! The most advanced species we know (us) is still confined to one planet. We'd be difficult to impossible to detect from Alpha Centauri, let alone Andromeda.
