"If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction."
- Frederik Pohl

| Big Push | ||
| A linear accelerator built on a long track; a mass driver. |
In principle, it is kind of like having a slingshot with a rubber band that is a hundred miles long. Put your vehicle on the track, then accelerate it until it can fly off.
| Probably there will never be another funeral like Jack's. The Big Push is only a third finished, and it's still two hundred miles of the biggest linear accelerator ever built, an electronic-powered railway crawling across the Earthside face of the Moon. One day we'll use it to launch starships. |

From the story Spirals by Niven and Pournelle.
The Space Studies Institute built prototype mass drivers as early as 1975; as far as I know, the concept originated with Gerard K. O'Neill in the early 1970's.
