Spock Has No Speculation (The Immunity Syndrome)

SPOCK: Indications of energy turbulence ahead. Unable to analyze. I've never encountered readings like this before.

KIRK: Scanners on. Magnification three on the screen.

KYLE: Magnification factor three, sir.

UHURA: Exactly what are we looking for, Mister Spock?

SPOCK: I would assume that.

(In the middle of the viewscreen is a black blob.)

KIRK: What is that?

CHEKOV: Perhaps an interstellar dust cloud.

SPOCK: Not very likely, Ensign.

KIRK: No. You'd be able to see stars through a dust cloud. Looks like a hole in space. Readings, Mister Spock.

SPOCK: Still not able to analyze, Captain. Sensors are feeding data to the computers now. Whatever this dark zone is, it lies directly in line with the course I calculate for the Intrepid and the Gamma Seven-A system.

KIRK: Hold present course. Slow to warp one.

KYLE: Warp factor one, sir.

KIRK: Mister Chekov, prepare to launch a telemetry probe into that zone. Direct computer feed to Mister Spock.

CHEKOV: Aye, sir. Probe ready. Switching data feed to library computer.

KIRK: Launch probe. CHEKOV: Probe launched, sir. (A high pitched sound comes over the Enterprise's speakers.) KIRK: What was that? UHURA: The telemetry probe, sir. There's no signal from it. KIRK: Speculation, Mister Spock. SPOCK: I have none, Captain. Insufficient data.
