&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
The phrase &amp;quot;slip the bonds of Earth&amp;quot; comes from the sonnet &amp;quot;[http://www.arlingtoncemetery.net/highflig.htm High Flight]&amp;quot; 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.&lt;br /&gt;
&lt;br /&gt;
The title text alludes to the unfortunate film ''{{w|The Core}}'', involving drilling to the center of the Earth to restart the stopped rotation of the magnetic core. 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 cheesy mission for the disaster.&lt;br /&gt;

The comic shows a sphere, representing the Earth, with three sets of what appear to be spaceships on three trajectories. One set is released with sufficient force to remain in a stable (elliptical and not circular in theory as they are not shot horizontally) orbit, while the other two fall towards the Earth. This is a replica of Newton's famous thought experiment involving a cannon on a high mountain, which demonstrates the effects of gravity on objects orbiting the Earth.&lt;br /&gt;
&lt;br /&gt;
Here, Newton's thought experiment is used to make the figurative and at the same time literal observation that a slight variation in parameter (impetus of the push) leads to totally different results. Society can choose the way of peaceful colonization of space and be able to explore the stars. Or it can choose to wage war and send intercontinental ballistic missiles (ICBMs) on a crash course and end the human civilisation in fire.&lt;br /&gt;
&lt;br /&gt;
Some - e.g. Elon Musk or Stephen Hawking and probably Arthur C. Clarke prominently - think or thought, respectively, the only chance of the human species to survive on long-term is to go to other planets.&lt;br /&gt;
&lt;br /&gt;
The title text alludes to the film The Core in which the trajectory would go straight to the center of the earth. This would be only possible, if you also change the angle (to straight upwards or straight downwards) and not only the force or by steering during the flight/the drill.&lt;br /&gt;

The comic shows a sphere, representing the Earth, with three sets of what appear to be spaceships on three trajectories. One set is released with sufficient force to remain in a stable orbit, while the other two fall towards the Earth. This is a replica of Newton's famous thought experiment involving a cannon on a high mountain, which demonstrates the effects of gravity on objects orbiting the Earth.&lt;br /&gt;
&lt;br /&gt;
Some - e.g. Elon Musk or Stephen Hawking - think or thought the only chance of the human species to survive on long-term is to go to other planets.&lt;br /&gt;
&lt;br /&gt;
Here, Newton's thought experiment is either used to make a satirical observation that if the cannonballs were spaceships, colony ships or intercontinental ballistic missiles (ICBMs), the resulting crash would end the human civilisation in fire, while if they achieved stable orbit, humanity would then be able to explore the stars, and/or used to show an analogy how on razor's edge the possible futures of our species are: A slight variation in parameter (impetus of the push) and you get totally different results.&lt;br /&gt;
