Gravitational Waves: What Happens to a Body Experiencing One?

In summary, when a body experiences a gravitational wave, the space within it expands and contracts, causing the distance between every point to also expand and contract. This can be observed by measuring the change in separation between two objects through interference. However, a strong gravitational wave is needed to overcome the bonding force between atomic particles.

What happens to a body experiencing a gravitational wave?
Suppose I put a ball in the path of a GR wave. As the wave passes through it, the space will expand and contract. This means that the space between every point in the ball should expand and contract. But what will be the reference point I should consider while looking at such king of deformation?

Also what happens to the distances between electrons and nucleus inside every atom?

I have a very amateur knowledge about this subject. If someone has good links for explanations please post.

Well, first of all it has to be a pretty impressive strong gravitational wave to overcome the bounding force between atomic particles. But in theory you should be able to measure the change in separation between two objects via interference.
 

1. What are gravitational waves?

Gravitational waves are ripples in the fabric of space-time caused by the acceleration of massive objects, such as two orbiting black holes or neutron stars.

2. How do gravitational waves affect a body?

When a body experiences a gravitational wave, it will be stretched and compressed along the direction of the wave's propagation, causing it to oscillate. This effect is strongest in objects with large masses and long lengths.

3. Can we detect gravitational waves on Earth?

Yes, we can detect gravitational waves on Earth using advanced instruments such as laser interferometers. These instruments measure tiny changes in the distance between two points caused by passing gravitational waves.

4. How do gravitational waves differ from electromagnetic waves?

Gravitational waves and electromagnetic waves are both forms of energy that travel through space, but they have different origins and properties. Gravitational waves are caused by the acceleration of massive objects, while electromagnetic waves are caused by the movement of charged particles.

5. What are the potential applications of studying gravitational waves?

Studying gravitational waves can provide valuable insights into the nature of gravity and the properties of the objects that create them. It can also help us better understand the evolution of the universe and potentially lead to new technologies, such as improved methods of detecting and measuring gravitational waves.
