Gravity Strength
Controls how strongly galaxies cluster together over time.

Comoving Scale
Adjust the visual zoom level in Comoving Space mode without affecting physics.
1.0
Heatmap Scale
Adjust the pixel size of the heatmap to simulate filaments (larger) or points (smaller).
4.0
Redshift Evolution
Controls the cosmic time. z=0 is today. At z>5, the view transitions to a composite view representing the early universe. (Use mouse wheel to adjust)
