Re: Hell of an approximation!
One meter difference does make optical interferometry quite unusable. Maybe they cut off some extra digits up to the nanometer scales to prevent us from getting too confused?
But then, the "approximately 22,000 miles" statement. I guess they are approximating interferometry on the mile boundaries. They must be listening in on the very low frequency AM transmissions coming from beyond the sun.
You do know that the sun's core is a gateway to another dimension, don't you? From there the aliens have been sending transmissions at low frequency. And surely, that we must pick up to join the intergalactic community. Rumours have it that the transmission contains the intergalactic community registration form.
