Burmer is a scientist; a molecular pathologist and expert in immunohistochemistry.
“As a passion, I have always loved astronomy,” she said in explaining her involvement in the project. Though a scientist, Burmer comes from a family of artists and musicians.
“Consequently, I’ve always wanted to try to synthesize science, art, and music, and this concert gives me the first-time opportunity to really do that,” she explained.
Among the challenges in doing a film about the Big Bang is that there’s no existing footage of the event, so creating visuals relied in part on particle animation technology. Burmer admits to being thrown off a bit by tensor calculus, membrane theory, and string theory, but she got enough understanding to help animators create a sequence demonstrating a Big Bang based on ekpyrotic theory. The animation shows two 3-D universes.
“They approach each other, they leak gravity, and they bud off our universe,” Burmer explained.

McQuinn noted that the best evidence for a hot Big Bang is that there is way more helium in the universe than could have been created by fusion in stars. The explanation is that, soon after the Big Bang, hydrogen fused much more easily in the hot, dense new universe. Astronomers have built models based on the measurements of the radiation in the cosmic microwave background and how much helium such conditions would produce.
“The predictions from the hot Big Bang model just fall perfectly on the measurements,” of what is actually out there, McQuinn said. “This, coupled with the fact that we have seen the cosmic microwave background, makes it almost indisputable that there was a hot Big Bang. No respected scientist questions this picture any more.”
McQuinn explained that galaxies eventually formed because of fluctuations in the density of mass and energy. An as-yet undetected particle called the inflaton may be the cause.
“This particle seeded these density fluctuations,” McQuinn said. “The predictions of this model are in striking agreement with what we see, so people think that this is the answer for the source of energy fluctuation.”
“From studying the cosmic microwave background radiation, we’ve come to these profound conclusions,” McQuinn concluded. “We’re able to explain the universe down to planetary scales.”
The “Origins” concert is part of the celebration of the 50th anniversary of the Department of Astronomy at the UW. The concert will feature the work of eight composers and accompanying celestial photography. It is a benefit for the scholarship program at the University of Washington Astrobiology Program in the Department of Astronomy. Tickets are $32, $22 for students, and are available online or by calling the Benaroya Hall ticket office at 206-215-4747.
