Albert Einstein
At the beginning of 1920, Einstein was asked what he thought about the idea of the existence of extraterrestrial intelligent life.
Einstein replied as follows: “Earth is not the only place where there is life. Probably, there may be inhabitants on the same Mars or some other objects of the Solar System, but I am not sure that they are intelligent. If we talk about progressive alien beings, then they will not communicate by radio.”
The great physicist of the XX century explained that it is convenient to use radio only at short distances, but if we want to make contact with distant “brothers in mind”, then we must learn to control light streams. So Albert Einstein predicted the creation of a laser.
