Jeff Trent: Ah, what's the use of makin' a fuss. Last night I saw a flyin' object that couldn't a possibly been from this planet, but I can't talk about it. I'm muzzled by Army Brass. I can't even admit I saw the thing!

Jeff Trent: I'm muzzled by army brass!

Jeff Trent: They here, they're a fact. And the Public oughta know about it!

Jeff Trent: You fiend.
Eros: I, a fiend? I am a soldier of our planet. I, a fiend? We did not come here as enemies.

Jeff Trent: You promise you'll lock the doors immediately?
Paula Trent: I promise. Besides, I'll be in bed before a half hour's gone... with your pillow beside me.
Jeff Trent: My pillow?
Paula Trent: Well, I have to have something to keep me company while you're away. Sometimes in the night, when it does get a little lonely, I reach over and touch it. Then it doesn't seem so lonely anymore.

Colonel Tom Edwards: ...Why, a particle of sunlight can't even be seen or measured.
Eros: Can you see or measure an atom? Yet you can *explode* one. A ray of sunlight is made up of *many* atoms!
Jeff Trent: So what if we *do* develop this Solanite bomb? We'd be even a stronger nation than now.
Eros: [with disgust] Stronger. You see? You see? Your stupid minds! Stupid! Stupid!
Jeff Trent: That's all I'm taking from you!
[pistol-whips Eros upside the head]

Colonel Tom Edwards: For a time we tried to contact them by radio but no response. Then they attacked a town, a small town I'll admit, but never the less a town of people, people who died."

Colonel Tom Edwards: This is the most fantastic story I've ever heard.
Jeff Trent: And every word of it's true, too.
Colonel Tom Edwards: That's the fantastic part of it.

Colonel Tom Edwards: Why is it so important that you want to contact the governments of our earth?
Eros: Because of death. Because all you of Earth are idiots.
Jeff Trent: Now you just hold on, Buster.
Eros: No, you hold on. First was your firecracker, a harmless explosive. Then your hand grenade: you began to kill your own people, a few at a time. Then the bomb. Then a larger bomb: many people are killed at one time. Then your scientists stumbled upon the atom bomb, split the atom. Then the hydrogen bomb, where you actually explode the air itself. Now you can arrange the total destruction of the entire universe served by our sun: The only explosion left is the Solaranite.
Colonel Tom Edwards: Why, there's no such thing.

Colonel Tom Edwards: You speak of Solaranite. But just what is it?
Eros: Take a can of your gasoline. Say this can of gasoline is the sun. Now, you spread a thin line of it to a ball, representing the earth. Now, the gasoline represents the sunlight, the sun particles. Here we saturate the ball with the gasoline, the sunlight. Then we put a flame to the ball. The flame will speedily travel around the earth, back along the line of gasoline to the can, or the sun itself. It will explode this source and spread to every place that gasoline, our sunlight, touches. Explode the sunlight here, gentlemen, you explode the universe. Explode the sunlight here and a chain reaction will occur direct to the sun itself and to all the planets that sunlight touches, to every planet in the universe. This is why you must be stopped. This is why any means must be used to stop you. In a friendly manner or as (it seems) you want it.
Lieutenant John Harper: He's mad.
Tanna: Mad? Is it mad that you destroy other people to save yourselves? You have done this. Is it mad that one country must destroy another to save themselves? You have also done this. How then is it "mad" that one planet must destroy another who threatens the very existence-...
Eros: [shoves her roughly aside] That's enough.
[to the humans]
Eros: In my land, women are for advancing the race, not for fighting man's battles.
