Walker estimated it might take 1,400 to 14 million years to contact E.T. with the out there know-how. That’s manner longer than researchers have spent listening for alien radio indicators and scouring the sky with telescopes and satellites (SN: 11/21/20, p. 18).
Regardless of the silence, scientists have despatched their very own messages into the void. In 1974, Earth despatched a string of binary code from the Arecibo Observatory in Puerto Rico. Years later, arguably essentially the most well-known message — the Golden Report — made its approach to area aboard NASA spacecraft (SN: 8/20/77, p. 124).
If aliens ever attain out, they could ship quantum dispatches, scientists say (SN: 8/13/22, p. 5). Even so, the aliens are doubtless so removed from Earth that their civilization can have collapsed by the point we get the message (SN: 4/14/18, p. 9).
