Detailed explanation-1: -The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made almost entirely of matter. Comparatively, there is not much antimatter to be found.

Detailed explanation-2: -Physicists think the cosmos started out with just as much antimatter as matter, but most of the former got wiped out.

Detailed explanation-3: -This created a small surplus of matter, and as the universe cooled, all the antimatter was destroyed, or annihilated, by an equal amount of matter, leaving a tiny surplus of matter. And it is this surplus that makes up everything we see in the universe today.

Detailed explanation-4: -But a plausible hypothesis is that the physical world was made up of a soup of short-lived elementary particles, including quarks, the building blocks of protons and neutrons. There was both matter and “antimatter” in roughly equal quantities.

Detailed explanation-5: -At that time, matter in the universe was in the form of a hot soup of quarks and gluons, called the quark-gluon plasma (QGP). As the Universe cooled further, the matter experienced a phase transition from this hot liquid soup into cooler individual particles, akin to water freezing to ice crystals when it cools.
