The strange quantum “Q balls” likely to explain the existence of the universe

Cosmologists are pretty sure of one thing. At the dawn of the universe, there were equal quantities of matter and D’antimatter. Theoretically, they should have annihilated each other. However, the matter does exist, and researchers are gradually discovering the reasons for it.

Today, a team of theoretical physicists seem to know how to find the answer. According to them, it would suffice to detect the gravitational waves produced by strange quantum objects, called “Q balls”. Balls whose existence is theoretical for the moment.

An existence of Q balls supported by physicists

In reality, the Q balls are “Lumps” theoretical formed after the Big Bang. These objects would contain unequal portions matter and antimatter. So when they had ” bursts “, they would have released more material than antimatter. According to our researchers, if these objects really existed, we could detect them thanks to gravitational waves.

A theory, proposed in 1985 by physicists Ian affleck and Michael dine of Princeton University, seeks to explain thematter-antimatter asymmetry of the universe. They had claimed that the fields which governed the swelling of the universe, similar to a balloon, had to be shallow enough for this swelling to take place.

Since inflation requires this uniformity, the field cannot interact too strongly with other fields to create particles. However, according to Affleck and Dine’s theory, this field interacted with others to ultimately create no more particles of matter than particles of antimatter. In order to maintain this uniform shape, the field contained these particles in ” parts “.

“These lumps are called Q balls. They are just pieces of field. “

The sound waves of Q balls to understand our universe

As the universe expands, these Q balls are remained in place.

“(…) Ultimately, they become the most important part of the universe in terms of the amount of energy they contain compared to the rest of the universe. “

Graham White, physicist at the Kavli Institute

However, they are not not eternal. When the Q balls disappear, they produce sound waves. According to the study, these sound waves are the source of the space-time ripples known asgravitational waves.

This theory is not the only one to explain the matter-antimatter asymmetry of the universe. On the other hand, according to White, that’s okay. Indeed, we would be at an exciting time when, if any of these paradigms turned out, we could possibly prove it.
