The model describes how the universe expanded from an initial state of extremely high density and high temperature. Detailed measurements of the degree of expansion of the universe place the event about 13.8 billion years ago, which is considered to be the era of the universe.
Soon after the Big Bang, cosmic inflation turned energy into matter, and physicists think that inflation created the same amount of matter and antimatter, which annihilate each other in contact.
But then something happened that shifted the scales in favor of matter, allowing everything we see and touch to exist – and a new study suggests that the explanation is hidden in very small space-time flows.
Jeff Dror, a postdoctoral fellow at the University of California, Berkeley, said: “If you just started with an equal amount of matter and antimatter, you would simply end up with nothing.”;
The response can surround particles known as neutrinos, which have no electrical charge and, therefore, can act as matter or antimatter.
The theory is that about a million years after the Big Bang, the universe cooled and underwent a phase transition, an event similar to how boiling water turns liquid into gas.
This change caused decay neutrinos to create more matter than antimatter from some “small, small amounts,” according to the study published in the journal Physical Review Letters.
Dr Dror added: “There are no very simple ways – or almost no way – to investigate [this theory] and find out if it really happened in the early universe. “
But Dr Dror and his team figured out a way we might be able to see this move in transition today, and therefore give the hypothesis more credit.

When the team modeled this hypothetical phase transition under different temperature conditions that could have occurred during this phase transition, they made an encouraging discovery.
They found that in all cases, the cosmic arrays would create gravitational waves that could be detected by future observers, such as the European Space Agency’s Space Interferometer Laser Interferometer (AIS).
Tanmay Vachaspati, a theoretical physicist at Arizona State University who was not part of the study, told Live Science in May: “If these wires are produced at high enough energy levels, they will indeed produce gravitational waves that can detected by scheduled observers. “
