The really bad dialogue appears on page 160. Wyman Ford is a new member of a team of scientists who have built and are trying to run a supercomputer. One of the team members has just told him that there's a small possibility that running the computer at 100% power might create a black hole that could sink to the earth's core and swallow matter until the earth is destroyed. Kate, another team member, tells him not to worry.
Ford lowered his voice. "Kate . . . Don't you think even the smallest possibility is too high? We're talking about the destruction of the earth."
"You can't shut down science on outlandish possibilities."
"Don't you care?"
Kate flared up. "Damn it, Wyman, of course I care. I live on this planet, too."
