...true, the finding is of literally cosmic significance: there are so many neutrinos in the universe that they alone could account for some 20% of the dark matter that inflation theory requires. Just add in another 80% worth of WIMPS and you've got it, says Joel Primack of the University of California, Santa Cruz. With this recipe, Primack has used supercomputers to produce synthetic universes that look almost identical to the data gathered by real-life astronomical observers. But some theorists think Primack is grasping too quickly at a "discovery" that is still controversial...
...inflation is correct, then, the age crisis is as bad as it can pos-sibly be. No amount of theory adjustment can bring stars down to 8 billion years of age. So if Freedman's initial attempt to date the universe holds up, Primack and plenty of other theorists may have to begin prying themselves away from an idea they have held dear for more than a decade-unless they can think of some clever...
...crisis. If the constant has the right value, then cosmologists can keep inflation. The cosmos would have started out in a long period described by scientists as "loitering" or "coasting," providing stars and galaxies with ample time to form. "Then," says Sandra Faber, Primack's Santa Cruz colleague, "suddenly the cosmological constant would kick in, gunning the expansion, making it faster." Measuring a large Hubble Constant and an apparently low age today, in other words, wouldn't be a reliable indicator of what was going on earlier in the universe's lifetime. Theorists might hate Einstein's abandoned child...
...should by rights have been flung out into deep space, unless, as Zwicky contended, the gravity from some massive, invisible substance was holding them in. For decades the idea was rejected as too bizarre. "It smacked of angels dancing on the head of a pin," recalls theoretical physcist Joel Primack of the University of California at Santa Cruz...
...Primack's enthusiasm for Scheme Z doesn't just stop with the plan, though, it extends to its MIT-educated architect. "Within the spectrum of highway engineers, Fred Salvucci is one of the most creative and brilliant men in the United Sates," Primack says...
