The Big Bang Never Existed? Researchers Propose The Big Bounce Theory

According to researchers, a new theory called the Big Bounce proposes that the Big Bang never occurred and that our universe actually sprang into life.

As researchers explain it the universe we live in today may have sprung to life thanks to the contraction of an ANCIENT universe that predates the one we live in today.

This new theory is shaking up the field of physics and could change everything we thought we knew about the origin of the universe.

Meet the “Big Bounce”, a theory that suggests the Cosmos could have been generated from the gravitational collapse of a much older Cosmos.

We know that the universe is expanding and the most common theory (The Big Bang) attributes this expansion to a sudden catastrophic explosion which is the moment when everything began to exist from infinitely dense, very hot material.

It’s as if something somehow managed to kick-start this process by which everything began to expand, creating space, time and matter as we know it. But what caused the initial explosion is exactly where questions about the Big Bang reside.

The Big Bang theory suggests that the explosion of a ‘ball’ of very hot, dense matter gave rise to everything we see today. The problem with that theory, however, is that while the predictions of this hypothesis work perfectly to understand what happened from the moment of the big bang to the present day, it suggests that the universe started from a state where none of the physical laws that we understand today are applicable.

The Big Bounce proposes something very different.

The model of the Big Bounce suggests that a previous universe collapsed giving rise to the one we inhabit today.

This new theory of the Big Bounce also has room for the Big Bang suggesting such a moment is possible, but not as an absolute beginning, but as part of a gigantic cycle where an ancient universe gave rise to the new one we live in today.

Even though the idea of the Big Bounce was first discussed in 1922, only recently have researchers given it more thought.

In the new study published in Physical Review Letters, scientists suggest that all particles in the early universe may have been governed by the law of quantum mechanics.

All of the above makes it possible for atoms to exist, preventing electrons from losing energy and eventually collapsing as they orbit the nucleus.

Researchers explain that even though quantum mechanics govern the behaviour of subatomic particles, everything changes with larger matter as it behaves entirely different, breaking the conformal symmetry present in smaller particles.

Looking at the early universe. scientists indicate that the same physical laws may have worked for the entire structure. Researchers further explain that rather than collapsing and destroying itself at the end of a period of contraction, it is likely that ‘somehow’ the universe was SAVED by quantum mechanics.
“Quantum mechanics saves us when things break down,’ said Dr Steffen Gielen from Imperial College London, an author of the study. It saves electrons from falling in and destroying atoms, so maybe it could also save the early universe from such violent beginnings and endings as the Big Bang and Big Crunch.”
The entire model was built upon an idea that the early universe had a conformal symmetry.

Researchers also included a couple of elements like radiation and nearly no ordinary matter that should have been present at the time.

It is through this model that scientists ‘predict’ that the universe we live in today could have SPRUNG into existence from a previous universe that was contracting.
“The big surprise in our work is that we could describe the earliest moments of the hot Big Bang quantum mechanically, under very reasonable and minimal assumptions about the matter present in the universe,’ said Dr Neil Turok, Director of the Perimeter Institute for Theoretical Physics in Canada, who was also involved in the study. Under these assumptions, the Big Bang was a ‘bounce,’ in which contraction reversed to expansion.”
