Is the Killer Crate Paradox Resolved?

Click For Summary
SUMMARY

The "Killer Crate Paradox" explores the implications of special relativity through a thought experiment involving two police officers, Bob and Alice, who analyze the feasibility of an assassination plot against physicist Dr. Katze. Bob believes the crate, launched at 0.70711c, can pass through the train window due to length contraction, while Alice argues it cannot due to the crate's altered shape and dimensions in her frame of reference. The discussion reveals that both perspectives are valid but stem from different interpretations of Lorentz transformations and the relativity of simultaneity. Ultimately, the paradox highlights the complexities of understanding relativistic effects on moving objects.

PREREQUISITES
  • Understanding of special relativity principles, including length contraction.
  • Familiarity with Lorentz transformations and their applications.
  • Knowledge of the relativity of simultaneity and its implications.
  • Basic grasp of vector decomposition in relativistic contexts.
NEXT STEPS
  • Study the implications of Lorentz transformations on moving objects in different frames of reference.
  • Explore the concept of the relativity of simultaneity in detail.
  • Learn about Wigner rotation and its effects on object orientation in relativistic scenarios.
  • Investigate other thought experiments in special relativity to deepen understanding.
USEFUL FOR

Physicists, students of relativity, and anyone interested in the complexities of special relativity and its paradoxes will benefit from this discussion.

As I said earlier, there is nothing really wrong with the formulas. The wrong assumption is that the angle ##\varphi = 135^\circ## corresponds to the vertical line. This is true only in the rest frame of the ellipse.

Yes. For calculating ##d##, I should have used either another angle (that of the related point on the circle, before "compressing" the circle to an ellipse) or the other formula for ##r(\varphi)## in posting #59.
