The Big Bang was not probably as we believed.

"A new cosmological model proposes that the universe grows not from a single Big Bang, but from multiple, rapid bursts of energy called temporal singularities. These unseen events may explain galaxy formation and cosmic acceleration—without relying on dark matter or dark energy. Credit: SciTechDaily.com" (ScitechDaily, No Big Bang? A Theory of Repeating Bursts Could Explain Everything)

In the new model, the Big Bang did not exist. Or its form was different. From we believed. It's possible that the Big Bang was a series of events that made the wave-particle duality from particles straight from the radiation. 

The new model of the universe's beginning is not as radical as it can be. The model is that the Big Bang was a series of events, not a single "bang". The idea of the Big Bang is that. There was an event where energy turned into material and those particles reached certain energy levels. 

There is the possibility that before modern material formed there formed some particle-antiparticle pairs that are very exotic in the modern universe. Those particles and their antiparticle pairs could be very common in the young, high-energy universe. 

There is a possibility that the very first gravitational centers, "Kugelblitz black holes". Those things formed when there formed whirls in the Higgs field. Those very first primordial black holes could explain the crossing waves that form the 

The energy or wave movement transformed into particles in the very high energy event that we call the "Big Bang". The only problem with the Big Bang model is that this thing. Wave-particle duality requires that wave movement impacts with opposite or crossing wave movement. 

When wave movement turns into particles. That requires crossing wave movement. There must be some source that sends those crossing waves. 

The wave-particle duality means that energy or wave movement can transform into a particle, or the particle can transform into energy. Those whirls can create crossing-wave movement. 

One of the possible models is that the Big Bang was a series of bursts that formed particles. There is a model. The Big Bang had multiple cores. The points where energy was released into the spacetime. When those energy waves crossed they formed particles that don't exist anymore. The young universe had a higher energy level than the modern universe. The energy flow from particles was slower than in the modern universe. 

That means there can be particles and atoms that cannot exist in the modern universe. The particle's ability to create compounds depends on the energy flow. That comes out from the particle. If that energy flow is too fast it pushes those particles away from each other.
