American physicists from Yale University and Duke University have recreated the conditions of the Big Bang in a laboratory to understand how matter behaved immediately after the formation of the universe. They concluded that most of the events around us occurred slightly after the original event. The research was published in the scientific journal magazine Physics Letters B (PLB).
According to experts, the early space was 250 thousand times hotter than the core of the Sun. This is too high a temperature to form the protons and neutrons that make up ordinary matter.
New calculations suggest that up to 70% of some measured particles come from subsequent reactions as the Universe expands. This is confirmed by the results of experiments carried out in colliders.
Scientists also found that the processes of new matter formation began 0.000001 seconds after the Big Bang, about the same time that the hot “soup” of primordial subatomic particles began to cool during the expansion.
Previously astronomers managed Find out the mass of the closest pulsar to Earth, a rapidly spinning neutron star.
