...national leaders have told the world that we will go "to any spot on this earth" in search of peace in Viet Nam [April 19]; yet the Administration immediately rejected Pnompenh and Warsaw as possible sites for talks. Lyndon Johnson's hands are irrefutably sullied with the blood of every American boy killed in Viet Nam from the time of that rejection until the day that peace talks do finally begin. Let the people of the world know that it is not all of America but only her highest leaders who quibble over "diplomatic etiquette" while...
Astrophysicist Richard Henry and his NRL associates crammed X-ray detectors into the nose of an Aerobee rock et last September and fired it high above the atmosphere, which absorbs X rays before they reach the earth. Telemetry from one detector designed to spot "soft" or low-energy X rays emanating from intergalactic space showed unexpectedly high readings. What- in apparently empty space - was producing this radiation...
...continued to proliferate beyond the pulsating neutron-star and white-dwarf-star theories first suggested by Cambridge astronomers. Princeton Astrophysicist Jeremiah Ostriker suggested that the signals might be caused by rapidly rotating white dwarfs with a local disturbance on their surfaces. Signals from the disturbance would sweep across the earth like a lighthouse beacon once during each rotation of such a star. British Astrophysicists Fred Hoyle and J. Narlikar propose that the signals are connected with supernovas, or exploding stars...
...have theorized that the pulses may be caused by white dwarf or neutron stars rotating rapidly around each other in a binary system; any particles passing through the rotating and intense magnetic field that must exist between the two stars would produce strong radiation that would periodically sweep the earth. Others have suggested that the intense gravity of a star in such a binary system would act as a lens, periodically intensifying and focusing the radiation from the twin star passing behind...
...signals, he notes, are transmitted over a very wide range of frequencies-an "enormously wasteful" procedure not to be expected of superintelligent beings. And if the signals from pulsar 1 are being transmitted in all directions from a distance of a few hundred light-years away from earth, the power level of the transmitting source must be about ten billion times greater than the entire electrical generating capacity of our civilization-"too high," Drake says, "to be plausible...
