On December 5, 2011, the PHENIX collaboration celebrated its 20th anniversary at a symposium, which began with some speakers’ recollections of early challenges and struggles in getting PHENIX approved, designed, and built. The speakers continued their talks with recounts of the many successes that occurred during the first 11 years of operations at RHIC, and ended with predictions of continued success for both RHIC and PHENIX in the next decade.
If a universe explodes into existence, and no one is around to hear it, does it still make a sound? The answer, according to RHIC physicist John Cramer, is a resounding yes. You can listen to the reverberations the Big Bang sent ringing through the cosmos in a new sound file based on the cosmic microwave background that originated at the birth of time.
