What’s a cyclic model?

The cyclic model suggests the universe is caught in an infinite series of cycles, with no start or end points. The universe expands and folds in on itself, creating an infinite assortment of universes. The cyclical model takes into account irregularities with the big bang model and is consistent with what is known about the universe. Cycles are a common state for natural phenomena, and researchers study cycles in various fields.

A cyclic model is a theory to explain the development and nature of the universe. It suggests that the universe is caught in a series of potentially infinite cycles; we could be living in the first ever universe, or the 137th universe, and there’s no way to be sure. Physicists have developed different forms of the cyclic model, incorporating components of string theory and other advanced theoretical physics. The more scientists learn about the universe, the more they can test these theories and develop new ones in response to emerging evidence.

According to this model, the universe is continually expanding and folding in on itself in a series of cycles. Instead of the big bang, experience more of a “big bounce.” As matter moves through the universe, it collapses on itself to create a singularity, which begins to expand again to start the next cycle. This could potentially go on indefinitely, as the cycles sustain and regulate themselves.

The universe has no specified start or end points in a cyclic model. Instead, it is caught in an endlessly repeating series of swings. Each oscillation can determine a different distribution of matter, creating an infinite assortment of universes. People or other life forms living in different cycles would not be able to access information about a previous or future cycle. Several scientists have hypothesized a variety of mechanisms for the cycling model, using the latest research findings to inform their theories.

One advantage of this approach is that it takes into account some irregularities with the big bang model once favored by researchers. As people learned more about the universe, especially the presence of dark matter, the big bang theory no longer fit the existing evidence. This is common in science, where researchers develop hypotheses to explain the world around them, adapting as more information emerges. The cyclical model provides an explanation for that which does not fit the big bang model; in the early 21st century, it was consistent with what was known about the universe.

Numerous other patterns in nature follow a similar cyclical pattern, illustrating that stable cycles are a common state for natural phenomena. Researchers study cycles ranging from the lifespan of parasites in waterways to the formation and collapse of galaxies. These natural patterns can interact with other cycles in complex ecosystems where multiple organisms and phenomena can be present.
