What if you could see a movie of cosmic history? A movie spanning back 8 billion years in time and through some 300 million galaxies?

Amazingly, a collaboration of research institutes and universities here in the United States have begun to do just that. The project is called the Dark Energy Survey and it is employing the use of a giant digital camera—the most powerful ever—to snap pictures of far out galaxies and exploding stars.

Scientists hope the information the camera gathers will help them solve one of the universe’s biggest mysteries: Why is the expansion of the universe accelerating?

Joshua Frieman is director of the Dark Energy Survey and a scientist at Fermilab. He is also a professor of Astronomy and Astrophysics at the University of Chicago. He joins The Takeaway to discuss what we know about dark energy and the expanding universe, and what the world may learn through this project.

In the seventies, The Hayden Planetarium used to have light shows on Saturday Night with music by Zeppelin and Pink Floyd. Young people would watch the lights and smoke weed.
The Dark Energy Survey sounds like it could continue that tradition and be a double feature with 2001 a Space Odyssey.
I wouldn't mind reliving those teenage years.
