Possibly the big bang suggested came from a point where no time or space existed (possible SCM) and this suggest that the space could continue to expand without stopping as long no time or space existed at that point.

Should put a disclaimer, but what the hell!!
The Standard Cosmological Model (or Lambda Cold Dark Matter Model) was developed to explain the CMBR, the large scale of galaxy clusters, the distribution of the light elements and the accelerating expansion of the universe (using redshift). It is the simplest model that is in general agreement with observed phenomena. The model uses the 'FLRW metric', the 'Friedmann Equations' and the 'Cosmological Equations of State' to describe the observable universe from the inflationary stage to the present and into the future.

The ultimate fate of an expanding universe depends on the matter density ΩM and the dark energy density ΩΛ proportions of the cosmological constant. Both are terms from the Lambda CDM Standard Model.

With evidence available at the moment, it is likely that the universe will continue to expand indefinitely, resulting in the "big freeze" scenario.
However a lot of this depends on the nature of dark matter and how it interacts with gravity and dark energy. The end result may be an oscillating universe.

There are many other theories about "The End".
