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

In summary, the speed of gravity is theoretically equal to the speed of light, and an experiment was conducted a few years ago to determine this. However, the results of the experiment are not certain.

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.

1. How does gravity travel through space?

Gravity is thought to travel through space in the form of gravitational waves, which are ripples in the fabric of spacetime. These waves are produced by massive objects and travel at the speed of light.

2. Is there a delay in the effects of gravity over long distances?

Yes, there is a delay in the effects of gravity over long distances. Since gravity travels at the speed of light, it takes time for the gravitational waves to reach distant objects. This means that the effects of a change in gravity may not be felt instantaneously on the other side of the universe.

3. How long does it take for a change in gravity to be felt on the other side of the universe?

The exact amount of time it takes for a change in gravity to be felt on the other side of the universe is not known, as it depends on the distance between the objects and the strength of the gravitational force. However, it is estimated that it would take several billion years for a change in gravity to be felt on the other side of the observable universe.

4. Can gravity be blocked or shielded?

No, gravity cannot be blocked or shielded. Unlike other fundamental forces, such as electromagnetism, there is no known way to block or shield the effects of gravity. This is because gravity is a property of spacetime itself and not a force that can be obstructed.

5. Could a change in gravity on the other side of the universe affect us?

Yes, a change in gravity on the other side of the universe could potentially affect us. However, since the effects of a change in gravity take time to travel, the impact would not be immediate and may be too small to notice. Additionally, the effects of gravity from distant objects are often balanced out by the gravitational forces of other nearby objects.
