GRAVITY WAVES
A set of bubble/film experiments (2023) utilized new light apparatus that produced a shadowgraph effect from the oscillating bubble nucleus onto a sheet of paper.

Gravitational waves (left) from the oscillating tad-pole nucleus (right), originally as a rotating barred spiral.
In this context, galaxies, blackholes, large-scale astrophysical structure and densities in oscillating gravitational fields radiate waves at varied frequencies and amplitude. Converting information to gravitational wave maps requires utilization of computational fluid dynamic algorithms, which express object size/mass and wave geometry. Colliding fields at stages of evolutionemit active and complex non-uniform gravitational waves.

Experiments with one bubble collapsing into another expanding bubble/film created gravitational effects on a reversed time scale. The donor nuclei are contracting in the expanding field.

A detail of the shadowgraph has stochastic features like observed CMB polarization.
