Some of the early ideas Gauss, the mathematician, suggested that we get in touch with ET by making large geometric structures on the planet, a right triangle, maybe three four five miles on a side. You can see the spacecraft leaving the earth traveling at about a hundred thousand miles an hour going out to the stars and questions in SETI is are there good planets out there going around other stars.
And if you had asked me 20 years ago are there planets going on other stars I would said I don’t know nobody knew at that 20 years ago but that has all changed.
