"What we're doing really is opening a new window into astronomy," Siemens said, who has personally spent 15 years on this project.
He says the discovery involves the first ever detection of a gravitational wave, from when two massive black holes collided, each 30 times the size of our sun.
"So these two black holes merged 1.3 billion years ago and those gravitational waves traveled to us," he said. "I think that sort of inspires a sense of awe and a sense of wonder in our place in the universe."
The discovery is considered a milestone in science and confirms a prediction made by Albert Einstein more than 100 years ago in his theory of relativity.
The work involved in this discovery began in the 1970s.
Siemens says UWM's support of this project was instrumental in its success and he's excited to see what else they discover.
More than 1,000 people across the world had a role in the discovery.
This work is one of three major experiments the team at UWM is working on, including one that involves radio telescopes.
A public lecture will be held Friday, Oct. 6 at 8 p.m. with more information about their work. The lecture will be in the atrium of the Kenwood Interdisciplinary Research Complex at 3135 N. Maryland Ave.
