Virologist John Enders, with his struggles to understand submicroscopic organisms, has...
At the farthest end of the space science spectrum is a project to listen for messages sent by intelligent creatures living on planets revolving around other stars than the sun. This project was made plausible by Harvard's Physics Professor Edward Purcell, who was the first to detect the 21...
A further subtlety, says Purcell. is that when the aliens turn their transmitter toward the sun, they will know the speed at which their star is approaching the solar system or receding from it. They will therefore allow for the slight shift of frequency caused by this motion. They may...
What message will the aliens send if they want to be understood by earthlings? Purcell suggests that a simple on-off signal will be easiest to detect, and is most likely to be sent. But he speculates that many messages of varying difficulty may be sent simultaneously, which is not...
