Intercontinental missiles will hasten the day of deadlock already implicit in intercontinental airplanes with hydrogen bombs. For several years, the U.S., complacent of its ability to stay ahead of Russia in all things technological, has been daintily fingering missile projects...
...confidence, which proved illusory, was much higher. Americans of 1954 knew that the technical peace was not real, that they had to keep almost 3,000,000 men under arms, maintain a peacetime conscription and spend an average of $855 a family for defense. The year that saw the hydrogen explosion at Bikini?the biggest explosion in man's explosive history?was not one to foster illusions about an indefinite peace...
...carved out by Vickers tractors and earth movers. And this is only half the business. For defense, Vickers also makes shells, cannon and 50-ton Centurion tanks, battleships (the 44,460-ton King George V), carriers (the 31,790-ton Illustrious), destroyers, a new type sub that runs on hydrogen peroxide, jet fighters and bombers for the R.A.F...
When the pressure reaches about 800,000 atmospheres, a strange thing happens to hydrogen. Its molecular structure collapses, and it turns into a metal much heavier than nonmetallic solid hydrogen. No such pressure can be reached in the earth's laboratories, but theoretical studies have proved that metallic hydrogen is a reality. Since the pressure at the center of Jupiter is something like 30 million atmospheres, there is plenty of room for a sphere of metallic hydrogen...
Professor Ramsey believes that Saturn has a similar structure. Uranus and Neptune are mostly ammonia and methane. Recent studies by M.J.M. Bernal and H.S.W. Massey at University College in London have shown that ammonia joins with hydrogen at 250,000 atmospheres to form metallic "ammonium": NH4. So the interiors of Neptune and Uranus probably contain another metal made out of a gas by pressure...
