As the consultancy universe expands, it becomes more difficult to categorise companies by type of work.

First, dark energy influences how the universe expands, so it affects how the volume grows over time.

Thus, the universe expands - rather than shrinks - by definition.

Absent of dark energy, a flat universe expands forever but at a continually decelerating rate, with expansion asymptotically approaching zero.

Even without dark energy, a negatively curved universe expands forever, with gravity barely slowing the rate of expansion.
