Can We Actually Detect Gravitational Waves with Atoms? | Peter Graham

Send us Fan MailWhat happens when a psychiatrist sits down with a Stanford physics professor to talk about gravitational waves, dark matter, quantum mechanics, and atoms existing in two places at once?In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler talks with Stanford Physicist Peter Graham about the strange and fascinating world of modern physics. What starts as a conversation about gravitational wave detection quickly turns into a deep exploration of quantum mechanics, atom interferometry, atomic clocks, dark matter, and the bizarre reality of particles behaving like waves.Peter explains how researchers are building tabletop experiments capable of measuring incredibly small distortions in space-time, why gravity is surprisingly weak compared to electromagnetism, and how a single atom can exist in two places at once. Along the way, Aaron asks the kinds of questions many listeners are probably thinking themselves, leading to a conversation that feels less like a formal interview and more like two curious minds trying to make sense of the universe together.This episode is not a simplified science lecture. It’s an intellectually alive conversation about uncertainty, experimentation, physics, and the limits of human intuition.About the GuestPeter Graham is a professor of physics at Stanford University whose research focuses on fundamental physics, dark matter, gravitational waves, and precision measurement techniques using atomic systems. His work often bridges theoretical physics and experimental collaboration, helping develop new ways to probe some of the deepest unanswered questions in modern science.Connect with Peter:Website: https://physics.stanford.edu/people/peter-grahamChapters 00:00 – Introduction to Peter Graham and Stanford Physics03:20 – Why Collaboration Matters in Modern Physics05:10 – The Problem with Dark Matter and Fundamental Physics06:00 – Building New Experiments Instead of Bigger Colliders07:00 – How LIGO Detects Gravitational Waves09:30 – Why Gravity Is Surprisingly Weak11:20 – Gravitons, Dark Matter, and Unanswered Questions15:15 – Atom Interferometry Explained18:00 – Quantum Mechanics and Probability Waves24:40 – Using Lasers to Manipulate Atoms29:20 – The History of Particle Physics and Scientific Discovery33:00 – What Quantum Waves Actually Mean41:00 – Vacuum Chambers, Cooling Atoms, and Laser Physics47:00 – How Laser Cooling Works55:00 – Creating an Atomic Interferometer1:00:30 – Measuring Time with Atomic Clocks1:08:00 – Using Atoms to Detect Gravitational Waves1:15:00 – Earth’s Gravity, Potential Energy, and Quantum States1:20:00 – Why Vertical Mine Shafts Matter1:24:00 – Measuring Acceleration with Atomic Systems1:28:00 – Building the Future of Gravitational Wave DetectionIf you enjoyed this episode of No Reason to Get Excited, make sure to follow the show, leave a rating or review, and share this episode with someone who loves deep conversations about science, physics, and the mysteries of the universe.Connect with Dr. Aaron WinklerWebsite: www.aaronwinklermd.comLinkedIn: @NRTGEPODInstagram @NRTGEPOD
