Is it true that, if there was enough dark matter in the universe it could stop the expansion of it?
If it is, can someone explain to me how?

nicksauce said:or the universe is at the critical density and will expand forever (this is called a flat universe)
PhilKravitz said:Would it be correct to say that in a flat universe the expansion rate decreases asymptotically and that the size of the universe increases asymptotically never exceeding a certain size?
Dark matter is a type of matter that is believed to make up approximately 85% of the total matter in the universe. It does not emit or absorb light, making it invisible to telescopes and difficult to detect. Its existence is inferred by its gravitational effects on visible matter.
Dark matter is thought to play a crucial role in the expansion of the universe. It is believed to provide the necessary gravitational pull to counteract the expansion caused by dark energy, allowing for a stable and steady expansion of the universe.
While dark matter does have a significant influence on the expansion of the universe, it is not believed to be able to stop it completely. The expansion of the universe is a result of multiple factors, including dark energy, and it is unlikely that any single factor, including dark matter, can completely halt it.
Dark matter is being studied through various methods, including observations of its gravitational effects on visible matter, as well as experiments such as the Large Hadron Collider. Detecting dark matter directly is challenging, but scientists are using advanced technologies such as underground detectors and particle accelerators to try and identify it.
The presence and behavior of dark matter is crucial in determining the ultimate fate of the universe. If the amount and distribution of dark matter are not fully understood, it could greatly impact our understanding of the universe's future. Some theories suggest that dark matter may eventually lead to a collapse of the universe, while others propose a never-ending cycle of expansion and contraction.
