Eternal Cycle of the Death and Rebirth of the Cosmos Continues Since Its Birth

The Big Bounce theory says the cosmos is locked in an eternal cycle of birth, death, and rebirth, bouncing back where it began in an eternal loop of unending time.

A new cosmos theory says an eternal cycle of rebirth and death will start when the first atoms become what the material universe is.

Reality comprises individual photons and particles, each of which originates from and ends in nothing. Stars die, galaxies expire, and until the next cycle, time begins and ends.

Creation From Singularity

What if the current models of cosmic creation have more to them? Suppose the universe does not end in a mighty crunch but will inflate again and again for untold eons like a lung, reported Science Alert.

Not one of the most popular theories out there, for some cosmologists, it could be an endless drama of creation and destruction in a never-ending loop. Is the Big Bang not what it is but a Big Bounce instead?

Physicists have now demonstrated that the Big Bounce hypothesis' most recent iteration, which addresses fundamental problems with past iterations, nonetheless has some significant flaws.

Will Kinney from Buffalo University stated the bouncing universes which stretch from an infinite past. It shows the newest model might not work, noted Buffalo Edu.

What the new model suggests is the entropy problem. If universal cycles of creation are evidence, then all have a starting point.

For now, a universal model of the cosmos, accepted by academics about the origin of the physical universe, came from an unknown singularity to what is now a cosmic reality.

The concept of an eternal cycle of life and death, then a beginning from an end, adds a rumple. Everything expanded from nothing 13.8 billion years ago when time and space did not exist; somehow, creation escaped from that singularity but how, noted Space.

Models that support the Big Bang and what this time in the universe's beginning is like are unclear; nobody knows what it is.

The Big Bounce idea, as a substitute, might completely solve the singularity issue. Instead, a contracting universe might rebound before it encounters a model-breaking event. An endless universe that forever bounces will experience eternal entropy, which is the disorder in cosmic reality.

The entropy level would be extremely high if a never-ending succession of big bangs occurred sequentially as smaller bangs, but this is not the case. Universal rebirth will also be destroyed by excess entropy.

The Big Bounce Theory

The Big Bounce got a second lease of life in 2019 when a revised model included an answer to the problem of excessive entropy. For every expansion of the cosmic fabric, there will be entropy that threatens to collapse the universe to an inflated state until it reinflates again.

This proposed model allowed it to be a probable cosmic creation theory, and predictably there were holes in a new model again.

Kinney and physicist Nina Stein ran the numbers and discovered that an infinite universe would not stretch into an infinite past. They solved the entropy dilemma, and the universe now has a plausible beginning, said Kinney. The proof is that, generally, a cyclic model removing the concept of entropy allows an eternally repeating universe on eternal cosmic playback.

Another concept is physicist Roger Penrose's cyclic universe model, called conformal cyclic cosmology. The universe gets more complicated from here as the cosmos repeats an eternal cycle of rebirth and death, which is relevant to the Big Bounce.
