Let's outline the facts based on most popular theories,
The burst of energy at the time of Big Bang created the initial rapid inflation of space.
The residual expansion had continued for another 7 billion years.
Mattr creation increased the gravity which have slowed down the expansion.
It is proposed that the space expansion of the next seven billion years is due to dark energy.
The nature of dark energy is not known.
The expansion of the universe is accelerating is accelerating.
If the matter density in the universe is constant (critical density), Then matter creation has to continue along the space expansion.
The above are few points which should be able to to bring the discusssion in the track.

Hey Mohsen:
Steady State advocate here.
With the proposed accelerating expansion of corporeal matter, the density of the spatial universe remains steady, because matter itself is proportionately enlarging with the enlargement of space, ad infinitum..
In accordance with my interpretations, 'dark energy' is another - (new, 1998 vintaged) - word for what used to be called (Einstein's) 'cosmological constant' - a repelling force generated by all matter, 'just like gravity' but causing things to move outwardly instead of inwardly. Unlike gravity, the cosmological constant (dark energy) force increases - instead of decreasing - with distance. This is why the universe is not merely expanding, but rather undergoing an accelerating expansion. The more distant the light source, the faster it is receding.
Good to hear from you; best regards,
