Do moving masses create another field, similar to how a moving charge

In summary, moving masses can create a tiny field known as the gravitomagnetic field, according to current theory. This concept was first proposed by Lense and Thirring in 1918 using Einstein's Theory of General Relativity, and is also referred to as the Lense-Thirring field. This term is often used to describe the effect in a simplified, linearized version of General Relativity. The conversation partners are discussing this concept and its origins, with one expressing their interest in the topic.

Yes, albeit, a very tiny (gravitomaqnetic) field according to current theory.
Why do you ask?

Please, what "current theory"?

In 1918 Lense and Thirring, originally developed the idea using Einstein's newly developed Theory of General Relativity. And so the effect, which was originally derived for rotational motion, is generally referred to as the Lense-Thirring field.

Today, the term 'gravitomagnetism' is popularly used and often refers to its deveopment from a 'linearized' version of Gen Rel.

I ask because I read about it somewhere and thought it was very interesting.
 

1. Do moving masses create another field?

Yes, according to Einstein's theory of relativity, any object with mass creates a gravitational field around it. When that object is in motion, the gravitational field also changes, creating a new field.

2. Is this new field similar to the electromagnetic field created by a moving charge?

Yes, the new gravitational field created by a moving mass is similar to the electromagnetic field created by a moving charge. Both fields have the ability to influence other objects in their vicinity.

3. How does the new field created by a moving mass differ from the original gravitational field?

The new field created by a moving mass is different in that it has additional effects, such as frame-dragging, which is the dragging of space and time around a massive object. This effect is not present in the original gravitational field.

4. Can the effects of the new field be observed and measured?

Yes, the effects of the new field can be observed and measured through various experiments, such as the Gravity Probe B mission which measured the frame-dragging effect of Earth's mass on surrounding space and time.

5. Are there any practical applications of this concept?

Yes, understanding the effects of a moving mass on gravitational fields is crucial in the fields of astrophysics and space travel. It also plays a role in the development of technologies such as advanced navigation systems and precision instruments.
