Martin Rees in his book Just Six Numbers says that in the early universe there 1 billion antiquarks and a billion and one quarks. Is that really known? How is known what the ratio of antiquarks to quarks was?
The ratio of quarks to antiquarks is approximately 1:1 in the universe. This means that for every quark, there is an antiquark with the same mass, but opposite charge.
Quarks and antiquarks can interact through the strong nuclear force, which is responsible for binding them together to form protons and neutrons. They can also interact through the weak nuclear force, which is responsible for radioactive decay.
The ratio of quarks to antiquarks is significant in particle physics because it helps us understand the behavior of subatomic particles and the fundamental forces that govern them. It also plays a role in theories such as the Big Bang and the creation of matter in the early universe.
The ratio of quarks to antiquarks is not constant throughout the universe. It can vary in different regions due to various factors such as temperature, pressure, and energy levels. However, on a larger scale, the overall ratio remains close to 1:1.
The ratio of quarks to antiquarks can change over time due to processes such as particle annihilation and creation. In the early stages of the universe, the ratio was not 1:1, but as the universe expanded and cooled, it evolved to its current ratio. It can also change in extreme environments such as in the cores of stars or during high-energy collisions in particle accelerators.
