Understanding CP Violation in Physics

Study Notes

Origin of Matter

Excess matter survived the annihilation of matter and antimatter, forming the basis of everything in the universe.
The laws of nature exhibit asymmetry in the treatment of matter and antimatter, highlighted by the phenomenon known as CP violation.
Research continues to explore the reasons behind matter's dominance in the early universe.

Formation of Atoms

Within the universe's first second, conditions allowed matter to form protons and neutrons.
After approximately three minutes, these protons and neutrons combined to create hydrogen (75% of matter) and helium (25%).
The abundance of helium corroborates predictions made by big bang theory, with scientific observations supporting this claim.

Recombination and Cosmic Microwave Background

The universe remained too hot for stable atoms to form, resulting in a dense, charged fog where light struggled to penetrate.
Recombination occurred roughly 380,000 years post-big bang, allowing for the formation of neutral atoms and leading to a transparent universe.
This transparency initiated the release of photons, which resulted in cosmic microwave background radiation, detectable throughout the universe.
The cosmic microwave background is the oldest radiation recognized, providing insights into the universe's formative moments.

Emergence of Stars

Stars first formed around 180 million years after the big bang due to gravity consolidating hydrogen clouds.
Dark matter, a mysterious substance, is theorized to outweigh visible matter by a factor of more than five and may have played a crucial role as a gravitational foundation for the first galaxies and stars.
