Story summary
- CERN demonstrated that quark-gluon plasma can be produced in much smaller particle collisions.
- Previously, such plasma was recreated only with heavy-ion collisions like lead nuclei.
- Researchers aim to use these micro-big-bang collisions to probe conditions a millionth of a second after the big bang.
- Physicists are testing how small a collision can be while still behaving like a fluid.
