The "Neutrino exceed the speed of light issue" was an actual story from the day before the comic was posted. An experiment at CERN caused a stream of neutrinos to be passed from CERN in Switzerland to a receiving station at the INFN laboratories of Gran Sasso in Italy (LNGS). The initial findings from the experiment were that the neutrinos arrived at the detector in less time than a beam of light would have taken. The neutrinos had apparently exceeded the speed of light.
Albert Einstein famously posited that the speed of light in a vacuum is both constant and absolutely the fastest possible speed in the universe. Nothing can go faster. Therefore, a report that neutrinos have been found travelling faster than light challenges a fundamental law of physics and turns all of physics, or at least special relativity on its head.
Prior experience has shown Cueball that in such cases, arguing with people and preaching caution is futile. Cueball realizes that it is more satisfying and profitable to place bets with them instead. His reasoning is that almost invariably, these supposedly world-changing discoveries end up falling apart after further investigation, and that if it doesn't, he wouldn't care.
Postscript: Cueball (that is, Randall) was correct. The experiment was found to be flawed. Neutrinos are not faster than light, the data was probably wrong due to an incorrectly synchronized clock, or caused by some broken wiring on the receiving end.
- [Megan and Cueball are talking.]
- Megan: Did you see the neutrino speed of light thing?
- Cueball: Yup! Good news; I need the cash.
- Megan: Huh? Cash?
- [Text above half-sized panel.]
- Yeah. When there's a news story about a study overturning all of physics, I used to urge caution, remind people that experts aren't all stupid, and end up in pointless arguments about Galileo.

- Cueball: No, this isn't about whether relativity exists. If it didn't, your GPS wouldn't work.
- Cueball: What do you mean, "science thought police"? Have you seen our budget? We couldn't begin to afford our own thought police.
- [Megan and Cueball talking again.]
- Megan: That sounds miserable and unfulfilling.
- Cueball: Yup. So I gave up, and now I just find excited believers and bet them $200 each that the new result won't pan out.
- [Same as last panel.]
- Megan: That's mean.
- Cueball: It provides a good income, and if I'm ever wrong, I'll be too excited about the new physics to notice the loss.
