The opposite of expansion is contraction. For an activity where expansion is simply an increase, the opposite can be reduction.
The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
Enlargement, release, expansion, freedom...
It is backronym. The opposite of acronym....!!!!! Or more appropriately use the terms expansion and long-form for opposites. =]
There is no opposite of dark energy in the sense that there exists something that is the exact opposite of dark energy.

The "opposite" suffix of -estatis or -statis (meaning a stoppage or unchanging condition) could be either-kinesis (motion)-ectasia (expansion, dilation)-genesis (growth)-lysis (destruction)-phthisis (growing)-tropia (turning)* If the intended suffix was -ectasia (expansion) rather than statis, the opposite would be stenosis (narrowing).
Usually they are opposite processes. Factorisation is taking an algebraic expression and partitioning it into factors in brackets (or parentheses). Expansion is taking such brackets and multiplying them out to a simple - if lengthy - expression.
The general opposite of to contract is to expand.In terms of biology, an opening would dilate (widen) as opposed to contracting or narrowing in size.For a muscle, the opposite of contract would be relax.
Thermal expansion of the combusting gases in the rocket nozzles (bottom of the rocket) pushes them against the outside air, and the equal-and-opposite reaction is to push the rocket upward.
