if any aliens did use standard energy to communicate, (and they were more advanced than us), they'd be using narrow band laser-type communication devices...
due to the minimalized signal strength fall off at long distances...
if not something so conventional (ie, if their tech was higher, they'd be using either tacyons or even most likely - Einstein coupled particles (where changing spin on one of them instantly changes spin on its 'brother', regardless of distance)...
these really are the most likely forms of long distance alien communication, which is why we need to get it
