Then, down the crowded thoroughfare comes theUniversity of Cambridges most distinctive vehic

In the motorized wheelchair, boyish face dimly illuminated by a glowingcomputer screen attached to the left armrest, is Stephen William Hawking, 46, one ofthe worlds greatest theoretical physicists. As he skillfully maneuvers through thecrowd, motorists slo
6、w down, some honking their horns in greeting. People wave and shouthello.A huge smile lights up Hawkings bespectacled face, but he cannot wave or shout back.Since his early 20s, he has suffered from amyotrophic lateral sclerosis (ALS), aprogressive deterioration of the central nervous system that us
7、ually causes deathwithin three or four years. Hawkings illness has advanced more slowly, and now seemsalmost to have stabilized. Still, it has robbed him of virtually all movement. He hasno control over most of his muscles, cannot dress or eat by himself and has lost hisvoice. Now he speaks only by
8、using the slight voluntary movement left in his handsand fingers to operate his wheelchairs built-in computer and voice synthesizer.While ALS has made Hawking a virtual prisoner in his own body, it has left his courageand humor intact, his intellect free to roam. And roam it does, from the infinites
9、imalto the infinite, from the subatomic realm to the far reaches of the universe. In thecourse of these mental expeditions, Hawking has conceived startling new theories aboutblack holes and the disorderly events that immediately followed the Big Bang from whichthe universe sprang. More recently, he
10、has shaken both physicists and ted lessformidable. But what really made the difference, he says, was that I got engaged toJane, who was studying modern languages at Cambridge. This gave me something to liverfor. As he explains, if we were to get married, I had to get a job. And to get a job,I had to
11、 finish my Ph. D. I started, working hard for the first time in my life. Tomy surprise, I found I liked it.What particularly interested Stephen was singularities, strange beasts predicted bygeneral relativity. Einsteins equations indicated that when a star several timeslarger than the sun exhausts i
12、ts nuclear fuel and collapses, its matter crushes togetherat its center with such force that it forms a singularity, an infinitely dense pointwith no dimensions and irresistible gravity. A voluminous region surrounding thesingularity becomes a black hole, from which ?because of that immense gravity
13、?nothing,not even light, can escape.Scientists years ago found compelling evidence that black holes exist, but they wereuncomfortable with singularities, because all scientific laws break down at thesepoints. Most physicists believed that in the real universe the object at the heart ofa black hole w
14、ould be small (but not dimensionless) and extremely dense (but notinfinitely so). Enter Hawking. While still a graduate student, he and MathematicianRoger Penrose developed new techniquesproving mathematically that if generalrelativity is correct, singularities must exist. Hawking went on to demonst
15、rate ?againif general relativity is correct ?that the entire universe must have sprung from asingularity. As he wrote in his 1966 Ph. D. thesis, There is a singularity in our past.Stephen later discerned several new characteristics of black holes and demonstratedthat the amazing forces of the Big Ba
16、ng would have created mini-black holes, each witha mass about that of a terrestrial mountain, but no larger than the subatomic proton.Then, applying the quantum theory (which accurately describes the random, uncertainsubatomic world) instead of general relativity (which, it turns out, falters in tha
17、ttiny realm), Hawking was startled to find that the mini-black holes must emit particlesand radiation. Even more remarkable, the little holes would gradually evaporate and,10 billion years or so after their creation, explode with the energy or millions ofH-bombs.Hawking has visited the U. S. 30 time
18、s, made seven trips to Moscow, taken around-the-word journey, and piloted his wheelchair on the Great Wall of China. On theroad, the activities occasionally deviate somewhat from physics. One night Stephenaccompanied a group to a Chicago discotheque, where he joined in the festivities bywheeling ont

The universe would not be created, not be destroyed; it would simplybe, he concludes, adding challengingl
