...size of a grapefruit, almost instantaneously, when the whole thing was .000000000000000000000000000000000001 sec. old. This turbo-expansion was driven by something like dark energy but a whole lot stronger. What we call the universe, in short, came from almost nowhere in next to no time. Says M.I.T.'s Alan Guth, a pioneer of inflation theory: "I call the universe the ultimate free lunch." One of the consequences of inflation, predicted 20 years ago, was that the universe must be flat--as it now turns...
...that's true, then trillions of these baby universes exist, for that's how many black holes are believed to inhabit our cosmos. And those are just the naturally occurring ones; baby universes could in principle be manufactured as well. M.I.T. physicist Alan Guth realized in the late '80s that you might create a baby universe in the lab from just a few pounds' worth of matter by compressing the stuff to black-hole density...
Since 1965, astronomers have had powerful evidence that the cosmos began with a Big Bang and that everything has been expanding outward ever since. But in the 1970s and early '80s, U.S. and Russian physicists (including Guth) realized that powerful energy fields dominating the cosmos when it was a fraction of a second old could have turbocharged the expansion, forcing the universe to fly apart--or "inflate"--at a rate many times faster than the speed of light. (The light barrier can't be broken by things moving through space, but space itself is exempt from this universal speed limit...
...many ways, the physics of these budding cosmoses are like the baby universes Hawking and Guth hatch inside black holes. The difference is that unlike the details of what transpires in black holes, the evidence for or against inflation could be settled within just a few years. If the universe did inflate, that brief period of breakneck expansion should have left a telltale pattern imprinted on the radiation left over from the Big Bang, which still echoes around the universe in the form of electromagnetic microwaves. Two satellites set to be launched later this year are sensitive enough to detect...
...spite of the aggressive commercial campaign, a mere 800 of the 11,000 Gaucher's patients who need treatment have signed up for Ceredase. One who refused, Denver teacher Karen Guth, estimates she would need to spend $350,000 for the drug each year. "It's a terrible position to put human beings in," she says...
