FSU researchers part of TESSERACT's hunt for dark matter

Tallahassee, FL (SPX) Mar 25, 2025
For decades, people have been trying to directly detect dark matter: the missing mass in our universe. Now, research from the FAMU-FSU College of Engineering is making possible a new, super-sensitive detector - and even though it's still in the research and development phase, it's already been able to search for kinds of dark matter that other detectors can't find. Historically, most dark matter searches have hunted for two kinds of dark matter: ultra-light axions and heavier WIMPs (weakly interac ... read more
