Subject: Expanding Universe.
We do not know the ultimate fate of the universe, but the leading ideas are that it expands forever, collapses and starts over, or ends in something more extreme.
Most current models lean toward a universe that keeps expanding and grows colder, darker, and more diffuse over immense spans of time. That view is driven by evidence that expansion is accelerating, including supernova measurements, the cosmic microwave background, and large-scale galaxy structure.
