Science Journalism
Explanation
The Joke
A scientist is being interviewed about experimental results. When asked what the experiment found, the scientist explains: "Either we had a slight measuring error or all of physics is wrong." The next panel shows a newspaper headline that reads: "EXPERIMENT MAY OVERTURN EINSTEIN" with the subheadline "All physics is wrong says scientist."
The Humor
The comic satirizes how science journalism consistently sensationalizes research findings. The scientist presents two possibilities -- a mundane one (a slight measuring error, which is extremely common and far more likely) and an extraordinary one (all of physics being wrong). Any reasonable interpretation would weight heavily toward the measuring error. But the newspaper, in classic science journalism fashion, seizes on the most dramatic possible interpretation and runs it as a headline, completely ignoring the far more probable explanation.
This is a well-known pattern in science reporting, where tentative findings, minor anomalies, or speculative conclusions are blown up into revolutionary-sounding headlines. The reference to Einstein makes it even more pointed, as "overturning Einstein" is a perennial favorite of sensationalist science reporting, despite the fact that general and special relativity have been confirmed to extraordinary precision.
References
The comic likely alludes to real incidents such as the 2011 OPERA experiment, which initially appeared to show neutrinos traveling faster than light (which would indeed "overturn Einstein"). The anomaly was widely reported with breathless headlines, but was later found to be caused by a loose fiber optic cable -- essentially a measuring error, just as the scientist in the comic suggests.
