Gravity is not instantaneous; it travels at a measurable speed

In short: While we experience gravity as an eternal, constant force, physics reveals it has a finite velocity. This video from Fermilab explains the definitive observation that measures how fast gravitational influence actually moves through the universe.

Dr. Don Lincoln of Fermilab explores the transition from viewing gravity as an unchanging background to understanding it as a dynamic interaction with a specific speed. The presentation highlights key observations that allow scientists to quantify this velocity, moving beyond the intuition that gravity acts across space immediately.
