Force causing increase in velocity.

(astronomy, astrophysics) A theory that describes and seeks to explain the seemingly increasing rate of the expansion of the universe.

Protein inhibiting complement system activation.

Hub for rapid developmental progress.

Fibers that increase speed, efficiency.

Observations show that the expansion of the universe is accelerating, such that the velocity at which a distant galaxy recedes from the observer is continuously increasing with time.

In futures studies and the history of technology, accelerating change is the observed exponential nature of the rate of technological change in recent history, which may suggest faster and more profound change in the future and may or may not be accompanied by equally profound social and cultural change.
