im trying to recreate this effect in autodesk maya. do you have any tips? im wondering if I can form this pattern with a texture

@oEQjet
Yes. Yes it does. All cosmological calculation depends upon the speed of light. If it wasn't known, none of this could be calculated.

Does this simulation account for the speed of ligiht?
Actually... I couldn't think of an even remotely plausible way to simulate that...

@jNode Thanks, will do.

@goliathlup1 indeed, the very early universe is thought to have been homogeneous and isotropic. for an interesting account of the stuff believed to have happened in the beginning, see steven weinberg's "the first three minutes".

@goliathlup1 ...not at all:-) only after ~400k years the universe became transparent and light started to travel (after being opaque, see decoupling in physical cosmology). this is also when the cosmic microwave background radiation was produced, which is observe today. the inhomogeneous distribution of this afterglow acted as the seeds for structure formation and are thought to have arisen from thermal variations generated by quantum fluctuations at early stages in the cosmic evolution.

@goliathlup1 actually, the redshift of the light observed from distant objects which can be equated with an age of the universe (e.g., z = 8.6, corresponds to 600 million years after the big bang singularity, says wikipedia)...

@jNode Redshift of the initial light from the "big bang"? An other question that might sound stupid, does the distribution of mass begin as homogenous? If so why would one particle move to one direction and not to an other?
Awesome video thanks.

@easgair
No, the video "ignores" expansion and focusses on the growh the structure in the universe.
