Learning about the beginning of the universe in trillions of degrees
CU Boulder Professor Jamie Nagle will discuss the quarks and gluons that formed at the Big Bang in his Distinguished Research Lecture Feb. 6
Ten trillion degrees Fahrenheit is unfathomably hot—more than 10,000 times hotter than the Sun’s core—and it’s the temperature of the universe just moments after the Big Bang. At such extreme temperatures, according to nuclear theory, ordinary matter made of protons and neutrons transforms into a plasma of fundamental particles called quarks and gluons.
At the world’s most powerful accelerators, scientists recreate tiny droplets of this early-universe matter by colliding heavy nuclei at near-light speeds. One of these scientists is Jamie Nagle, a University of Colorado Boulder professor of physics who for 20 years has studied these fleeting droplets and, along with his research group, engineered their shapes, sizes and temperatures to better understand their properties.
Nagle will discuss this work in the 125th Distinguished Research Lecture, “10 Trillion Degrees: Unlocking the Secrets of the Early Universe,” at 4 p.m. Feb. 6. in the Chancellor's Hall and Auditorium of the Center for Academic Success and Engagement (CASE).
About Jamie Nagle
Nagle has spent much of his career investigating the early universe through high-energy nuclear physics. His research has focused on understanding the quark-gluon plasma, a state of matter theorized to have existed just microseconds after the Big Bang.
“As you go back to about six microseconds after the universe started, the temperature was around two trillion Kelvin,” Nagle explains. “It was theorized that protons and neutrons inside of nuclei would melt away, creating a bath of more fundamental particles—quarks and gluons.”
Nagle's work involves recreating droplets of this quark-gluon plasma in a laboratory by colliding large nuclei at nearly the speed of light. These collisions occur at the world’s highest-energy accelerators, including the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in New York and the Large Hadron Collider (LHC) in Geneva, Switzerland.
“In the world's highest-energy accelerators, we can collide very large nuclei like gold, lead or platinum at such high velocities that we create a tiny droplet of this 2 trillion Kelvin plasma,” he says.
What: 125th Distinguished Research Lecture, 10 Trillion Degrees: Unlocking the Secrets of the Early Universe
Who: Professor Jamie Nagle of the Department of Physics
When: 4-5 p.m. Feb. 6, followed by a Q&A and reception
Where: Chancellor's Hall and Auditorium, Center for Academic Success and Engagement (CASE)
Reflecting on the award, Nagle expresses gratitude and a sense of accomplishment: “It means a lot to me. You get to a certain middle age and are more self-confident, but this recognition feels rewarding. There's a lot of effort, and much of the hard work goes unnoticed. It’s nice to feel like the fruits of that labor are appreciated.”
The Distinguished Research Lectureship also emphasizes communicating complex scientific concepts to broader audiences. For Nagle, this is a vital part of his work: “This award is very meaningful to me because I often listen to the lectures of past recipients. It's about communicating the broader context of why this scientific research is important, not just within the microcosm of nuclear physics.”
About the Distinguished Research Lectureship
TheDistinguished Research Lectureshipis among the highest honors given by faculty to a faculty colleague at CUBoulder. Each year, the Research and Innovation Office requests nominations from faculty for this award, and a faculty review panel recommends one or more faculty members as recipients.
The lectureship honors tenured faculty members, research professors (associate or full) or adjoint professors who have been with CU Boulder for at least five years and are widely recognized for a distinguished body of academic or creative achievement and prominence, as well as contributions to the educational and service missions of CUBoulder. Each recipient typically givesa lecture in the fall or spring following selection and receives a $2,000 honorarium.
