@Winther dense materials will be more dense due to gravitational attraction .

so there will be a big force (and potential energy) for expanding of dense materials at big bang .

my be that is dark energy .

In the pre-inflation version of the Big Bang theory, very high relative velocities are part of the hypothesis on the very early state of the Universe. In the inflation theory, this is a consequence of the inflationnary accelerated expansion phase (which in particular involves some analogue of the "dark energy", where by "dark energy" I mean the cause of the recent accelerated expansion of the Universe).
