Motion as metric — 2D Interactive Simulator

Special Relativity kinematics in absolute space

This 2D simulator implements the null-loop rules—fixed carrier speed and work-free bending as defined in the paper Motion-as-Metric: Relativity and Gravity Without Curvature (https://zenodo.org/records/17151372)

Open the index.html page in a modern browser to run. 

Users can see contraction, dilation, and do radar ranging directly at speeds up to 0.95

3 different views are supported, absolute fixed, absolute follow and self-relative mode.
The self-relative mode compensates for time dilation (we do this by changing c_abs as if it were the update step) and contraction (pure canvas strech after draw).
Due to this compensation, two way measurement times in self-relative mode take  equal time in user seconds at any speed. 

Fly around with arrow keys, take two way radar measurement with space. HUD display on the left keeps last 10 measurements. Ideal measurement is 2xPi;.

Play with parameters on the right hand side. 

Lower number of constituents and bigger radius cause measurement imprecision due to low circulation rate (which is what we measure time by in the loop frame). 
Longer radar rods naturally aid precision. 
Gravity is WIP and limited to 0.65c.
          
This software is intended as complementary proof-of-concept demonstration and a pedagogical aid
