Title:
Challenging Einstein: Lunar Laser Ranging as an Absolute Test
Speaker:
Abstract:
General Relativity is one of two foundational pillars of physics, yet gravity is the most weakly tested of the fundamental forces. Using the pristine solar system as a laboratory, we bump into this pillar to see if it might fall. This talk will describe many facets of the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) and how we can push an order-of-magnitude advance on our knowledge of fundamental gravity. Preliminary results from a new Absolute Calibration System will be highlighted, which moves APOLLO from millimeter range precision to millimeter accuracy.
