XKCD WTF? II

[Kitty Sinatra]

Seriously, WTF?

What's the deal with the philosopher on Neptune? Why did he pass on the obvious opening in Uranus? Is this really just an elaborate Your Mother joke?

 

[General Specific]

The chart represents the gravity wells of the various planets and moons. Imagine the wells are a cliff face you have to scale in order to escape that particular planet's gravity.

To answer your questions:
That would be Carl Sagan, just a basic reference, really. It'd be too easy to make that kind of joke. Essentially, yes.

Just a quick note, we are working on the image resizer. As it stands it does not show full size when clicked, apparently. We are looking for a solution.
