Did you notice the subtle joke in the joke on panel 4?

I didn't want to believe. Of course on some level I realized it was a known-plaintext attack. But I couldn't admit it until I saw for myself.

(Emphasis mine.) I thought that was great. It's so pedantic, yet it explains everything neatly.

Wormhole Physics Introduction

A wormhole in normal conditions can be held open for a maximum of just under 39 minutes. Conditions that can increase the time include a powerful energy source coupled to one or both of the gates connecting the wormhole, and a large gravity well (such as a black hole).

Momentum is preserved across the wormhole. Electromagnetic radiation can travel in both directions through a wormhole, but matter cannot.

When a wormhole is created, a vortex normally forms. Warning: The vortex caused by the wormhole opening will annihilate anything in its path. Vortexes can be avoided when using sufficiently advanced dialing technology.

An obstruction in a gate will prevent it from accepting a wormhole connection.
