How It Might be Sent: Light Signals "It is absurd to say that communication with Mars is hopelessly impossible. We have never tried it."
In*these words Dr. A. M. Low, the inventor, summed up his own point of view with regard to a much debated problem. He believes that an attempt, even if unsuccessful, could not but teach us something, if only of the method of signalling employed.
"The method I consider most hopeful is light-signalling," he said recently in a "Daily News" interview.
There are several known chemical means of producing a light screen of sufficient size, which would last long enough to be noticed by Martians if such exist.
"D rather think that a suitable screen could be set out at a high altitude by aeroplanes, in order to eliminate as far as possible the effect of the air and clouds, which combine to make difficult any observation of the earth itself."
