SUMMARY

This discussion focuses on real experiments that explore the speed of gravity, specifically referencing the Shapiro delay effect. The Shapiro delay demonstrates how light is affected by gravitational fields, suggesting a difference in wavefronts between light and gravitational waves. The work of Kopeikin and Formalont is highlighted as a controversial example in this field. Understanding these concepts is crucial for grasping the nuances of gravitational wave propagation.

PREREQUISITES
  • Understanding of gravitational wave theory
  • Familiarity with the Shapiro delay phenomenon
  • Knowledge of wavefront propagation in physics
  • Basic comprehension of experimental physics methodologies
NEXT STEPS
  • Research the Shapiro delay and its implications on light and gravity
  • Study the Kopeikin and Formalont experiment in detail
  • Explore the differences between gravitational waves and electromagnetic waves
  • Investigate other experiments measuring the speed of gravity
USEFUL FOR

Physicists, astrophysicists, and students interested in gravitational wave research and the fundamental principles of gravity.

Can you advice a good list of real experiments related to speed of gravity?

And here is simple thought experiment:

version 1 with Shapiro delay
.....................|
.....................|
....................|
(source of gravitational and light wave)..>......(star)
.....................|
.....................|
.....................|
version 2 without Shapiro delay

As I understand wavefront of light would look like in version 1.
But which type of wavefront would have gravitational wave?
 
Physics news on Phys.org
Kopeikin and Formalont [http://arxiv.org/abs/astro-ph/03110632003] is one example. It is, however, controversial.
