“
None that I could understand, but he did illustrate his point with a thought experiment. It’s called the Infinite Hallway.” Langdon paused, taking another sip of coffee. “Yes, a helpful illustration,” Winston chimed in before Langdon could speak. “It goes like this: imagine yourself walking down a long hallway—a corridor so long that it’s impossible to see where you came from or where you’re going.” Langdon nodded, impressed by the breadth of Winston’s knowledge. “Then, behind you in the distance,” Winston continued, “you hear the sound of a bouncing ball. Sure enough, when you turn, you see a ball bouncing toward you. It is bouncing closer and closer, until it finally bounces past you, and just keeps going, bouncing into the distance and out of sight.” “Correct,” Langdon said. “The question is not: Is the ball bouncing? Because clearly, the ball is bouncing. We can observe it. The question is: Why is it bouncing? How did it start bouncing? Did someone kick it? Is it a special ball that simply enjoys bouncing? Are the laws of physics in this hallway such that the ball has no choice but to bounce forever?” “Gould’s point being,” Winston concluded, “that just as with evolution, we cannot see far enough into the past to know how the process began.” “Exactly,” Langdon said. “All we can do is observe that it is happening.” “This was similar, of course,” Winston said, “to the challenge of understanding the Big Bang. Cosmologists have devised elegant formulas to describe the expanding universe for any given Time—‘T’—in the past or future. However, when they try to look back to the instant when the Big Bang occurred—where T equals zero—the mathematics all goes mad, describing what seems to be a mystical speck of infinite heat and infinite density.” Langdon and Ambra looked at each other, impressed. “Correct again,” Langdon said. “And because the human mind is not equipped to handle ‘infinity’ very well, most scientists now discuss the universe only in terms of moments after the Big Bang—where T is greater than zero—which ensures that the mathematical does not turn mystical.
