- Dr. 'Doc' Gordon: The past, of course, still exists
- Mr. Denning: Oh?
- Dr. 'Doc' Gordon: Suppose a scientist on a planet some fifty light years from here were observing Earth, he would at this moment be looking at light rays that left this Earth fifty years ago. He might very well be watching the First World War. In effect, some full fifty years' of history would be contained in those beams traveling to that distant planet
- Mr. Denning: That's quite an idea!
- Dr. 'Doc' Gordon: It's more than an idea, Mr Denning, it's fact. And since space-time is a continuum, the present is only a point moving constantly along that continuum
- Mr. Denning: When you put it like that, Doctor, even I can understand it
- Dr. 'Doc' Gordon: Theoretically, with our equipment, we should be able to cut in anywhere along that continuum - actually journey to the center of time.
- Mr. Denning: Doctor, young Stanton isn't quite like his father. He hates to put the family money into anything that isn't going up.
- Mark Manning: Then why doesn't he put it all into taxes? That's the only thing sure to go up.
- Dr. 'Doc' Gordon: You shouldn't antagonize the man, Mark.
- Mark Manning: He's a pompous fool.
- Karen White: Mark, what will it be like?
- Mark Manning: Another Earth, another time. Who really knows? We may be the Adam and Eve of a brave new world.
- Stanton: What would you like, a serenade? Poetry?
- Karen White: Why not?
- Stanton: All right, I can be poetic. Let's see, a lady of science name White can travel much faster than light. She took off one day in a relative way and returned the previous night.
- Karen White: [laughs] You nut.
- Stanton: Denning, how long does my father have to be dead before you bury him?
- Mr. Denning: I don't understand.
- Stanton: Am I or am I not in full control of Stanton Industries?
- Mr. Denning: Why, of course.
- Stanton: Then we'll drop the Junior. I'm the only Stanton in Stanton Industries now.
