Scotty: Aye, Mr. Spock, and I found out why. The emergency bypass control of the matter/antimatter integrator is fused. it's completely useless. The engines are running wild. there is no way to get at them. We should reach maximum overload in 15 minutes.
Spock: I would calculate 14.87 minutes Mr. Scott.
Scotty: Those few seconds won't make any difference Mr. Spock. because you and I and the rest of the crew will no longer be here to bandy it back and forth. this thing is going to blow up, and there's nothing in the universe that can stop it.
