Yet, if there are gigantic alien
starships or space stations, the same factors that have caused
astronomers to rule out natural causes also apply to the alien
megastructure theory. If something is absorbing 20 percent of a
star's light, that energy should be re-radiated as infrared
wavelengths, plus, the structure is going to get really, really hot.
So far, no extra infrared wavelengths have been detected. If the
object was a giant Death-Star space-station, it should also have a
consistent orbit causing the periodic dips in light as it passed in
front of the star. At least my theory about a massive fleet of alien
starships passes that test, right? Ultimately, the only way we can
get closer to the answer is by repeated observations over a longer
span of time, possibly using other telescopes to generate a
cross-reference for collected data. Radio telescopes at SETI will
also be used to listen for alien broadcasts that might be made from
the star system. It's exciting that we may finally have somewhere
specific to start looking, and listening, for extra-terrestrial life!
