How to Measure Energy Carried by Gravitational Waves: A Pedestrian Version - Trautman-Bondi Energy
Offered By: Centrum Fizyki Teoretycznej PAN via YouTube
Course Description
Overview
Explore a simplified approach to measuring the energy carried by gravitational waves in this lecture by Prof. Jerzy Kijowski from the Center for Theoretical Physics PAS. Discover how field evolution can be described using "radiation data" instead of "Cauchy data" in a method applicable to any radiating system. Learn about the interpretation of Trautman-Bondi energy as the actual Hamiltonian density describing this evolution. Gain insights into an elementary mathematical approach that avoids constructing a fictitious "metric tensor at infinity." This one-hour presentation offers a pedestrian version of the Trautman-Bondi energy concept, making complex physics more accessible to a wider audience.
