That's two separate definitions of 'transmission' though isn't it?
In one you're using the relationship and forces between atoms to relay data physically, in the other you're using electromagnetic waves.

Yes, but the medium isn't the issue, the timing of the message is.
Anyway, its all theoretical bollocks. If I had an aldis lamp that worked at that distance it would have the power of a death star.

Now that would be worthwhile.

Actually, further to this
of course the nuclear forces holding atoms together cannot travel faster than light either, so the information would take the same time or fractionally less than an electromagnetic transmission anyway. Edit: and that's exactly what K2 said down there. Doh.
