"Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not."
- Isaac Asimov

| Gravity Well | ||
| If you visualize spacetime as a flat, elastic plane, a planet will deform it, and it sits at the bottom of its own hole. |
| 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. |
| From Life Cycle,
by Poul Anderson. Published by Magazine of Fantasy and Science Fiction in 1957 Additional resources -

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."
More recently, Charles Stross uses it in Accelerando (2005):
"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."
“Mars is just dumb mass at the bottom of a gravity well; there isn't even a biosphere there.”

With each successive print, our model needed to incorporate more structural ingredients to minimize print failures.
'... Wendis stared thoughtfully at the brilliant lines on the spectroscope screen.'
'A special spot-wavex scrambler also caused his televised image, in the area immediately about his lips, to mouth the vowels and consonants beautifully.'
