Researchers at Caltech have developed a way to create chilled molecules containing radium. This breakthrough could help solve one of the biggest mysteries in physics: why matter dominated over antimatter in the early universe.
For the first time, scientists have found a way to make cold radioactive molecules using the element radium. This achievement is significant because it will help researchers study one of the biggest unsolved puzzles in physics.
The mystery is how matter and antimatter were created in equal amounts in the early universe, but then matter dominated over antimatter. Antimatter is a type of matter that has the same mass as regular matter but opposite charges. When an electron (a negatively charged particle) meets its antimatter twin, the positron (a positively charged particle), they annihilate each other and turn back into energy.
To solve this mystery, researchers need to find out what difference or asymmetry between matter and antimatter caused matter to dominate. They are using lasers to study radium molecules, which have a unique shape that makes them ideal for these experiments.
Radium is a radioactive element that was first discovered by Marie Curie in 1898. It's highly reactive and hard to work with because it's only available in small quantities. The new research, published in Science, shows that scientists can now make radium molecules cold enough for tabletop experiments using lasers.
This breakthrough has the potential to help researchers understand why antimatter largely disappeared from our universe. Antimatter exists only in very small amounts and is hard to detect. Researchers like Nick Hutzler at Caltech are using smaller experiments, like this one with radium molecules, to search for clues.
Why It Matters
This discovery could help us understand the fundamental laws of physics that govern our universe. It's a mystery that has puzzled scientists for decades, and solving it could lead to new discoveries in fields like energy and medicine.
