What triggered the the Cyclic model of the origin of the universe?
The Cyclic model of the origin of the universe was triggered by the desire to explain certain cosmological phenomena that were not adequately addressed by the prevailing theories at the time, such as the Big Bang theory.
The Cyclic model proposes that the universe undergoes an endless series of cosmic cycles, with each cycle consisting of a contraction phase (known as the "Big Crunch") followed by an expansion phase (known as the "Big Bang"). In this model, the universe is not a one-time event but rather a perpetually recurring process.
The motivation behind this model stems from the need to explain certain observations, such as the uniformity of the cosmic microwave background radiation and the prevalence of dark matter, which are unexplained by the Big Bang theory alone. Additionally, the Cyclic model attempts to address the issue of the singularity present at the beginning of the universe in the Big Bang theory, where classical physics breaks down.
The Cyclic model suggests that during the contraction phase, the universe collapses to a high-energy state but does not reach a singularity. Instead, it enters a bounce phase, transitioning into the subsequent expansion phase. This avoids the need for explaining the singularity problem and provides a mechanism for the origin of the universe to be an ongoing process.
To summarize, the Cyclic model of the origin of the universe was triggered by the need to explain observed phenomena that were not satisfactorily addressed by the prevailing Big Bang theory, such as the uniformity of cosmic background radiation and the presence of dark matter, and to provide an alternative to the singularity problem.
