Cosmic Time Delay System

Evident, Gravity Propagates At The Speed Of Light

This is why Newtonian Gravity physics works great locally except at cosmic distance Einstein's General/Special Relativity is more accurate. Here's a summary example.

• _wikiGW170817 ~140 million light years away, two neutron stars collided.
• Mathematics suggest particular cosmological events happen upon impact.
• Gamma-ray burst and other EM signals of the right power levels for the collision were noticed by many detectors including Microwave Dish Systems and Gamma detecting arrays.
• 1.7 seconds before the first EM sources were measured gravity interference waves were measured at three different gravity wave detection facilities, Hanford, Washington, and Livingston, Louisiana, as well as the Virgo detector in Italy.

You'll probably find interesting that the interference patterns of gravity waves are seen over a large span of time with an increasing frequency of each wave caused by two massive cosmological objects revolving faster and faster from an ever tighter orbit until they collide in a merger.

How about a time system based on the delay from LIGO detected merging masses and a particular EM signal's arrival after? _cgptCosmic Time Delay, a ChatGPT-4o Idea =>
