The Big Bang is the beginning of everything in the universe, which has basically become the consensus of astronomy, physics and particle research, and this theory also believes that all time began at the moment of the Big Bang, all matter formed at the moment of the Big Bang, and everything also began at the moment of the Big Bang, so what happened at that moment? What has formed?
Recently, astrophysics researchers at the University of Copenhagen in Denmark published a paper in the journal Physics Letters b, arguing that a special plasma appeared within a microsecond after the Big Bang, and believed that it was the first substance to appear after the birth of the universe.
Astronomers have observed and deduced through the same phenomenon and background temperature of the universe that the universe began about 13.78 billion years ago, and believe that the universe exploded rapidly at that moment, but it is difficult to deduce what kind of explosion it is, but the European Hadron Collider can carry out simulation experiments, and scientists at the University of Copenhagen in Denmark made this discovery through it.
Zhou Zhou, an associate professor at the Nils Bohr Institute at the University of Copenhagen, said: The hadron collider accelerates two beams of protons to near the speed of light and causes them to collide together, collapsing into a substance with quarks and gluons adhering as the main body, which they call "quark-gluon plasma", which has not yet formed protons and neutrons, and the travel time is also very short, only one microsecond. That is, 1 millionth of a second, or 0.000001 seconds, after which this matter is transformed, and at the beginning of the Big Bang, what causes it to disappear is the expansion effect of the universe, and then they will merge, forming protons and neutrons, so qgp is also considered to be the basic component of atomic core matter.
Scientists also found that qgp once appeared as a flowing liquid form, it can constantly change the shape with time, like rolling water droplets, and the previous theory is that qgp should be a gas, but the test results of the hadron collider show that qgp is fluid-like, scientists say that it has a smooth and soft texture like water, so it is very similar to the surface material of the "water droplets" in the three-body!
But because it can change shape over time, scientists believe it is unlike any other known substance, and the researchers say the discovery is closer to the truth of the Big Bang, where the quark-gluon plasma is fluid before becoming hadrons and the cornerstone of life, and has a changing behavioral manifestation, which seems to be a tiny detail but a major breakthrough in physics to solve the mystery of the Big Bang.
Astrophysicists believe that the universe at the beginning of its birth is only a very small ball of pure energy, and it is from a very small point to erupt, and then matter begins to form, and the first formation is some elementary particles, and then the elementary particles synthesize atoms, just as quarks and gluon plasma synthesize protons, the most that appears is a combination of a proton and an electron, which is the hydrogen atom, the most material in the universe is the hydrogen atom, which still accounts for more than 90% of the total number of elements in the universe. Atoms and other elements gather together to form nebulae, nebulae can produce stars and planets, etc., star explosions can produce black holes, neutron stars, white dwarfs, etc., and various celestial bodies in the universe can be formed.
