US EditionThis Ancient Pristine Galaxy Validates the Big Bang
GENEVA, SWITZERLAND, JUL 20 – Scientists observed a 2.45% difference in decay rates between baryons and antibaryons, marking the first clear evidence of CP violation in baryons and shedding light on matter-antimatter asymmetry.
- Researchers at CERN observed a rare form of symmetry violation in beauty baryons during the LHCb experiment, marking a significant step in understanding the matter-antimatter imbalance in the universe.
- The study published in Nature reveals the first evidence of charge-parity violation in baryonic decay processes, which is crucial in explaining why matter dominates the universe.
- Findings indicated a significant difference in decay rates of beauty baryons and their antimatter counterparts, with a discrepancy of approximately 2.5 percent, supported by a statistical significance of 5.2 sigma.
- Lead author Xueting Yang stated that although the CP violation observed aligns with Standard Model predictions, it does not fully solve the matter-antimatter puzzle.

Have scientists decoded why the universe exists? Cern study points to matter-antimatter asymmetry
The finding offers vital clues to the long-standing mystery of why the universe is composed predominantly of matter, rather than being annihilated by an equal amount of antimatter
This ancient pristine galaxy validates the Big Bang
Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest elements were created originally: hydrogen, helium, and a tiny bit of lithium. For elements heavier than those, which astrophysicists call metals, a generation of stars had to live and die.
Scientists Just Found a New Matter-Antimatter Clue—and It Might Explain Why Anything Exists at All
If the Big Bang had played fair, you wouldn’t be reading this. Nothing would exist—not stars, not cheese, not you. That’s because, in theory, the universe should’ve created equal amounts of matter and antimatter. And those two tend to clash violently on contact. So if the scales had been balanced, the whole thing should’ve gone kaboom, leaving behind a cosmic “oops” and not much else. Instead, here we are. And physicists at CERN just found one m…
New clue to how matter outlasted antimatter at the big bang is found - West Hawaii Today
Understanding why matter and antimatter behave differently is key to understanding why there is a universe at all. Now physicists have discovered the latest example of a subtle difference between the stuff that makes up galaxies, stars, planets and us, and its evil-twin opposite.
