Bug-Rivet Paradox Calculator

Free explore relativistic length contraction in the bug-rivet paradox. calculate contracted lengths and understand simultaneity in special relativity.

Input Parameters

Hole is shorter than rivet at rest

As fraction of speed of light (0-0.999)

Results

Enter parameters to explore the paradox

Bug-Rivet Paradox

Length Contraction

L = L₀ × √(1 - v²/c²)

Moving objects appear shorter in the direction of motion

The Paradox

  • • In rivet frame: rivet contracts, fits in hole
  • • In hole frame: hole contracts, rivet doesn't fit
  • • Resolution: simultaneity is relative
  • • Events appear simultaneous in different orders
