Скачать или смотреть Visualizing Special Relativity: Comparing 3 Views of Crossing 4D Objects

Three Views of two 4D Objects (flanges or angle brackets) crossing at relativistic velocities 0.866c relative to the camera.

Special Relativistic Visualization created with 3D slices of 4D objects (flanges) crossing at 86.6% of the speed of light. The thee views (or stages) show:
A) Classic animation with infinite lightspeed;
B) Newtonian relativity with finite lightspeed; and
C) Special Relativistic Visualization (SRV) of finite lightspeed and Lorentz contraction.
At the apparent light delays (retarded time) seen in this simulation, the stages must be large enough to encompass the orbits of Jupiter's four largest moons.
Note that at 86.6% of c, the Lorentz contraction is 50%, as depicted in the bottom view.
Note also, that the length contraction is physically real, not just apparent.
