According to our best understanding of physics, the Big Bang should have created equal amounts of matter and antimatter, which would have annihilated each other completely. Yet here we are. This asymmetry is one of physics' deepest mysteries.
The Problem
Matter and antimatter are identical except for opposite charges. When they meet, they destroy each other completely, converting to pure energy. Standard physics predicts perfect symmetry, meaning nothing should remain.
Searching for Answers
Scientists are conducting precision experiments with antiparticles, looking for subtle differences between matter and antimatter that might explain the imbalance. Recent measurements show antimatter responds to gravity the same way as matter, ruling out one proposed explanation.
The answer may require entirely new physics beyond our current theoriesâperhaps the most important discovery waiting to be made.
