...drew matter to them, becoming denser still--a pattern preserved to this day in the distribution of galaxies, with huge clusters where there were high-density regions back then and great voids in between. Eventually, clouds of hydrogen became so dense that their cores ignited with the fires of thermonuclear reactions--the sustained hydrogen-bomb explosions, in essence, that we know as stars. But whereas the familiar stars of the Milky Way are mostly similar in mass to the sun, these first stars were, on average, gigantic--at least 25 times as massive as the sun and ranging as much...
...DARK MATTER Accounting for a bigger portion of matter than ordinary atoms, dark-matter particles were spread unevenly through the cosmos; areas of higher concentration drew in hydrogen and helium gas, gradually forming the first stars dense enough to burst into thermonuclear flame 3 FIRST STARS The earliest stars were massive, weighing in at 20 to more than 100 times the mass of the sun. The crushing pressures at their cores made them burn through their nuclear fuel in only a million years or so and caused them to spew radiation so intense that it kept other stars from forming...
...discovery means that any nation with a small supply of A-bombs may soon be able to use each A-bomb as a trigger for a thermonuclear bomb, thus easily and inexpensively multiplying the power of each A-bomb a thousandfold...
...Britain's House of Commons, 130 Laborites impulsively signed a petition asking the government "to take the initiative in every form they consider advisable in order to prevent the explosion of any further thermonuclear bombs." CALL OFF THAT BOMB, cried the hysterical wing of the British press...
...monitoring system picked up evidence of a Russian thermonuclear explosion that, if the educated guessers are right, was from a device far less complex, far more economical and far more "transportable" than Ivy's. Then, last month, came the U.S. explosion that Strauss described as being twice the estimated size. It became famous prematurely because an unexpected wind shift showered a Japanese fishing boat with radioactive ash. But the March 1 explosion (and the one that followed on March 26) had even more serious implications: in the global game of the scientists, where scores are read in terms...
