The comic shows the Earth, with three apparent rockets on separate trajectories. One is released with sufficient velocity to attain a stable orbit, while the other two fall towards the Earth. This is a slight modification of {{w|Newton's cannonball}}, a thought experiment demonstrating the planetary effects of gravity. | The comic shows the Earth, with three apparent rockets on separate trajectories.

− | + | Here, Newton's cannonball is used both to observe humanity’s technological future (interplanetary travel, availability of advanced technology to the masses, and constant scientific improvement; or nuclear desolation and the extinction of our species) and to underscore that argument by pointing out the inherent metaphor in the experiment: the cannonball can only escape the atmosphere by achieving high velocity (i.e. escape velocity). One might imagine that similarly, technological progress might only deliver us from nuclear extinction if it happens quickly; that otherwise, mankind will destroy itself. Of course, that threat only exists because of quick technological progress in the first place. | |

The phrase "slip the bonds of Earth" comes from the sonnet "[http://www.arlingtoncemetery.net/highflig.htm High Flight]" written in 1941 by John Gillespie Magee Jr., an American pilot in the Second World War. Portions of this poem appear on the headstones of many interred in Arlington National Cemetery, particularly aviators and astronauts; it was also quoted in [https://www.washingtonpost.com/news/morning-mix/wp/2016/01/28/how-ronald-reagan-explained-the-challenger-disaster-to-the-world-its-all-part-of-taking-a-chance/?utm_term=.0553e0d1d468 President Reagan's speech] after the Challenger disaster. | The phrase "slip the bonds of Earth" comes from the sonnet "[http://www.arlingtoncemetery.net/highflig.htm High Flight]" written in 1941 by John Gillespie Magee Jr., an American pilot in the Second World War.

If there had been one more line that returned to Earth much more quickly than the others, its trajectory would point toward the center of the earth. Apparently, not even Newton would predict such a disaster. |
