Sure but imagine what someone would have said before we discovered radio waves.

We don’t know that there is anything better, but given how much we don’t know it’s not unreasonable to consider that we might not have the technology to receive communications from more advanced civilizations.

I agree with you that RF is a good communication medium given what we know, I just don’t put much weight on our existing knowledge being all there is.

I said this:

I think the guy I replied to asked about "theories" of alternatives, and there isn't really anything specific as far as I'm aware; there's just this vague philosophical notion that we don't know what we don't know. I don't think anyone's denying it (I certainly am not) but there is not much else to be said on the subject. Knowing that we don't know what we don't know doesn't help us make predictions about what we don't know.

Do you know why people say that superluminal communication is impossible?
