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. $\endgroup$ –
WebUsage of fractions is recommended when more precision is needed. If we want to calculate how many Miles are 20000 Light Years we have to multiply 20000 by 8212439646337500 and divide the product by 1397. So for 20000 we have: (20000 × 8212439646337500) ÷ 1397 = 1.6424879292675E+20 ÷ 1397 = 1.1757250746367E+17 Miles. iowa wireless center moline illinoisWeb26 rijen · How long is 150 light years?
