is there any limit to the expansion of the universe? (Cosmological Expansion) Can anyone refer to some research papers on this topic?

Cosmological expansion refers to the phenomenon in which the universe is continuously expanding. This means that the distance between galaxies, stars, and other celestial bodies is increasing over time. It is one of the key observations that led to the development of the Big Bang theory.
Currently, there is no known limit to cosmological expansion. The expansion of the universe has been observed to be accelerating, meaning that the rate at which the universe is expanding is increasing. However, it is not known if this acceleration will continue indefinitely or if there is a limit to how much the universe can expand.
The age of the universe and the limit of cosmological expansion are interconnected concepts. The age of the universe is estimated to be around 13.8 billion years, which is based on the observed rate of expansion and the distances between galaxies. If there is a limit to cosmological expansion, it would affect the age of the universe as well.
There are different theories and models that suggest the expansion of the universe could eventually slow down and even reverse. One possibility is the "Big Crunch" theory, where the universe will eventually collapse back into a singularity. However, current observations and data suggest that the expansion of the universe will continue to accelerate.
Dark energy, a mysterious force that is responsible for the acceleration of the universe's expansion, is believed to play a significant role in defining the limit of cosmological expansion. It is not well understood, but it is thought to make up about 70% of the total energy in the universe. Its influence on the expansion of the universe is a topic of ongoing research and study.
