Other than our local cluster of galaxies, all galaxies are speeding away from each other. The farther away the galaxy, the faster it is moving away. This seems to be contrary to gravitation effects and seems to be related to the "big bang" of 13 billion (or so) years ago.

The Big Bang is responsible for the expansion of the universe, which affects the movement of galaxies. Galaxies are moving away from each other as the universe expands, with more distant galaxies moving faster due to the expansion. This overall expansion of space causes galaxies to move apart from each other.
It isn't quite clear to me what "initial movements" you refer to; but the general tendency is that anything that moves continues to move at a constant speed - unless some force makes it change its velocity. That's Newton's First Law.
Gravitation.
Yes, matter from the Big Bang is still moving. The expansion of the universe that began with the Big Bang is still ongoing, causing galaxies and other structures to move away from each other. This movement is evidenced by the redshift observed in the light from distant objects.
Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.
The spectrum of galaxies, including the distribution of their light, shows evidence of the expansion of the universe, as predicted by the Big Bang theory. The redshift of galaxy spectra indicates that galaxies are moving away from us, suggesting that the universe is expanding. This cosmic expansion provides crucial support for the Big Bang model of the universe's origin.
Given by the fact that electromegnetic energy cannot be seen and how the radiation from distant galaxies supports the big bang theory? it can easily be said that...I dont know the answer. (0_0)
