It will be eleven more years before we will know whether we can ever communicate with the Sirian men. The speed of light is too low for rapid communication, and as the first signals were sent out in September, 1961, and it is now September, 1968, the signals are not due to reach Sirius for two years more. Then it will be 1979 before we can hope to receive their reply. I often wonder if they will ever get those signals. I can remember distinctly the recoil of the great projector as the mighty surges of light flashed out across the universe. It seemed like some great gun--the back pressure of the light was so great. And what will those replies tell us? It is interesting to speculate on that subject. The End
