"Science fiction writers, I am sorry to say, really do not know anything. We can't talk about science, because our knowledge of it is limited and unofficial, and usually our fiction is dreadful."
- Philip K. Dick

| A paragravity-based shield for space craft. |
| "Only the particles with freak velocities can touch us," Drake went on. "We have a negative safety-field, that will stop everything under ten kilometers a second, and deflect a good deal of the rest."
The ugly face of Biggs showed a stubborn disbelief, and he tried to explain: "You can feel the peegee [paragravity] field, here in the ship, that holds you against the deck and keeps you from being space-sick? Well, there's a similar field around the hull, pushing away - you couldn't hit us with a rifle from fifty meters." |
