Is a change in gravity felt instantaneously on the other side of the universe?

AI Thread Summary
A change in gravity is theorized to propagate at the speed of light, denoted as c. Discussions reference past experiments aimed at measuring this speed, although the results of those experiments are uncertain. The concept raises questions about whether gravitational changes are felt instantaneously across vast distances in the universe. Theoretical physics supports the idea that gravity does not act instantaneously. Overall, the speed of gravity remains a topic of interest in physics, with ongoing inquiries into its implications.

Is a change in gravity felt instantaneously on the other "side" of the universe?

That is, does gravity travel instantaneously? Have we ever been able to measure the speed with which 'gravity travels'?

I'm pretty sure the speed of gravity is theoretically = to c. I think an experiment was done a few years ago to determine this actually... I'm not sure of the results.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
