Introduction: Far across the universe, pairs of supermassive black holes at the hearts of galaxies slowly orbit each other, moving as if in a cosmic dance.
These motions send ripples through space-time that travel for millions of years before reaching Earth.
By studying tiny variations in the radio signals from pulsars—nature’s most precise cosmic clocks—we are trying to capture these invisible waves.
In this science café, we’ll explore how researchers are learning to “listen” to the rhythm of dancing galaxies and what it tells us about our universe.
About the speaker:
Qiuyue joined Kavli IPMU in 2023. Her field of expertise is theoretical physics.
Time & Date: 2:00PM - 3:30PM, July 6 (Sun), 2025

Introduction: In this talk, we will explore the vast range of sizes found in the Universe, from black holes just a few meters across to the immense scale of the observable cosmos. We will journey through the evolution of the Universe, tracing its expansion from a singular point at the Big Bang to its current form, capable of hosting everything we see
today. Along the way, we will delve into the historical context of key discoveries that have shaped our understanding of cosmic scales. We will examine structures ranging from stars within our solar system and galaxies in diverse environments to the vast cosmic web, which contains clusters, filaments, walls, and immense voids. Finally, we will uncover how these large-scale structures encode clues about the enigmatic dark matter and dark energy—mysterious components that may ultimately determine the fate of the Universe.
