Explanation
The Joke
The comic proposes a "new rule for sports-writing": the phrase "physics defying" may only be used when it is actually applicable. We then see a news anchor putting this rule into practice, reporting that "in a physics-defying move, LeBron James' jumpshot detected a photon's momentum and position at the same time."
The Humor
Sports commentators frequently describe impressive athletic feats as "physics-defying," when in reality they are perfectly consistent with the laws of physics — a spectacular dunk or catch still obeys gravity and mechanics. The comic takes this literally: if you are going to call something "physics-defying," it had better actually violate a law of physics. The example given — simultaneously detecting a photon's momentum and position — would violate the Heisenberg Uncertainty Principle, one of the fundamental principles of quantum mechanics. This is the kind of event that would genuinely defy physics. The humor comes from the absurd contrast between mundane sports coverage and actual violations of fundamental physical laws, as well as the deadpan delivery of a news anchor casually reporting a violation of quantum mechanics during a basketball game.

The Heisenberg Uncertainty Principle states that you cannot simultaneously know both the exact position and exact momentum of a particle with arbitrary precision. This is not a limitation of measurement technology but a fundamental property of quantum systems. Werner Heisenberg formulated this principle in 1927.
