Many questions remain, … WebThe Warp Speed Calculator is designed to answer these questions. Simply input two of three variables (speed, distance, and time), and the form will calculate the third for you. It will even convert equivalent units, like years to days, light-years to parsecs, or warp factors to multiples of c. And you, too, can sound like a Treknology expert ... Web$\begingroup$ The question asks how far away could we detect life, not the other way around. In principle we could detect radio signals from as far away as you like if the signals were powerful enough (or directed). I really can't see where you have come up with the arbitrary figure of 100-150 light years. $\endgroup$ – lithic genealogy group scam
