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

Click For Summary

Discussion Overview

The discussion centers around the nature of gravity and whether changes in gravitational fields are felt instantaneously across vast distances in the universe. Participants explore the theoretical implications of gravity's speed and reference experimental attempts to measure it.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions if a change in gravity is felt instantaneously on the other side of the universe and whether gravity travels instantaneously.
  • Another participant asserts that the speed of gravity is theoretically equal to the speed of light (c) and mentions that an experiment was conducted to measure this, although they are uncertain about the results.
  • A repeated reference to an external link is made, indicating a potential source of information regarding the speed of gravity.

Areas of Agreement / Disagreement

Participants express differing levels of certainty regarding the speed of gravity, with some agreeing on the theoretical speed being equal to c, while others remain uncertain about experimental results.

Contextual Notes

There is a lack of clarity regarding the specifics of the experiment mentioned, including its results and methodology, which may affect the discussion's conclusions.

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.
