Will the universe stop expanding?

All constellations in the universe are currently moving apart from one another at a speed that is, at least for the time being, increasing.

Although the cause of the acceleration is unknown, dark energy is thought to be involved.

There would need to be a force, gravity, in the universe for it to begin contracting. However, it doesn't seem like there is enough gravity in the universe right now to slow down the rate of acceleration until it reverses.

Dark matter, which makes up approximately 95% of the known universe, is the wild card. If dark matter is associated with gravity, that would be sufficient to halt the expansion.

We have a lot to learn about the nascent fields of astronomy and quantum physics, and the unification of these fields may be achieved through the development of unified field theory.

According to what science currently knows, the universe will continue to expand indefinitely because dark energy—a mysterious force that opposes the pull of gravity—is what propels this expansion. The rate of expansion may vary over time, but there is no indication that the universe will eventually stop expanding.
