" I sometimes suspect that we're seeing something in the Internet as significant as the birth of cities. It's really something new, it's a new kind of civilization."
- William Gibson

| The surface of a planet. |
| He was the pilot and engineer, the only other Terrestrial on Mercury. When you dove this far down into the sun's monstrous gravitational well, you couldn't take a big crew along. |

This expression quickly became a favorite of veteran sf writers; Heinlein, Clarke and Niven used it within a few years. Here's Niven using it as the subject of a short story, At the Bottom of a Hole (1966):
"The hole." Garner knew enough Belters to have learned a little of their
slang.
"The very one. His first instinct must have been to change course.
Belters learn to avoid gravity wells. A man can get killed half a dozen
ways coming too close to a hole. A good autopilot will get him safely
around it, or program an in-and-out spin, or even land him at the bottom,
God forbid. But miners don't carry good autopilots. They carry cheap
autopilots, and they stay clear of holes."
"He must have been on course for Luna when we found him. Ceres was behind
him with the radar. Our ships were ahead of him, matching course at two
gee. His mining ship wouldn't throw more than point five gee, so
eventually they'd pull alongside him no matter what he did. Then he
noticed Mars was just ahead of him."

Technovelgy (that's tech-novel-gee!) is devoted to the creative science inventions and ideas of sf authors. Look for the Invention Category that interests you, the Glossary, the Invention Timeline, or see what's New.

'But when Old Father Sun departs, the chromoplastic reverts to transparency in the dark.'
'It extended three of its tiny arms sideways to lock onto the registration pins...'
'The grey gas not only cut off his vision, but also his other senses...'
'Mass-produced in the orbiting factories...'
'I enjoy watching this way, but - He waved his hand and the circuit switched abruptly.'
SF writers popularized and elaborated on this idea a generation before the first patents were filed.
'The autopilot would need data before it could begin a translation...'
'Sealed to the ground along all the sides, Honey, he growled...'
