[QUOTE="AlexB23, post: 77651165, member: 450900"] Yeah, cosmic rays could hit the CCD sensor, limiting laser distances also, but lasers can hold energy for longer. Hopefully ET does not use the hydrogen line (21 cm) band for radio comms, though they could use multiples of the band, say 0.25, 1.5, or 2x the frequency. You are very knowledgeable on comms technology. :) We need more people like you on CF. I'm a science guy also. [/QUOTE]
