The universe should not exist because of a cosmic imbalance
In short: According to the laws of physics, the Big Bang should have produced equal parts matter and antimatter. If that were true, they would have annihilated each other completely, leaving behind a void. Instead, we live in a universe dominated by matter. Solving this mystery is one of the greatest challenges in modern science.
Antimatter is defined as an identical version of normal matter but with an opposite electrical charge. While it behaves similarly to the atoms that make up our bodies and planets, its existence creates a profound cosmological paradox. Current scientific consensus suggests that during the Big Bang, matter and antimatter were created in perfectly equal amounts. Under these conditions, the two substances should have collided and neutralized one another entirely. This substance is considered one of the biggest mysteries in fundamental physics today. It remains a primary focus for researchers trying to map out our understanding of particle physics.
The fact that we exist today means something went wrong—or right—in the earliest moments of the universe. This 'puzzling imbalance' allowed a small residue of matter to survive while antimatter vanished. Understanding this mechanism is essential for physicists because it explains why the universe is populated with stars, galaxies, and people rather than being an empty expanse of radiation. The study of these interactions helps scientists explore the origins of everything we see around us. This research aims to clarify how early cosmic events led to our current reality.
To solve this mystery, researchers have constructed some of the most sophisticated experimental setups in human history. These include high-precision laboratories located deep underground to shield from interference, the massive infrastructure at CERN (the European Organization for Nuclear Research), and specialized experiments conducted aboard the International Space Station. By studying these elusive particles in extreme environments, scientists hope to determine how close we are to finally understanding why our universe chose matter over its mirror image. Professor Tara Shears will present the latest results from these diverse facilities. These findings allow observers to evaluate how much progress has been made in identifying this elusive material.
