Engineers work on the ATLAS detector in this time-lapse from science photographer @babaktafreshi. With a weight similar to the Eiffel Tower, this 7,000-ton, 46-meter long cylinder sits in a cavern 100 meters (yards) below ground, as part of the Large Hadron Collider at the CERN lab in Switzerland. This international effort to accelerate particles and observe their collisions may change our understanding of matter—and the history of the universe. Music by tonelabs.
