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

Click For Summary

Discussion Overview

The discussion revolves around whether moving masses create a field analogous to the magnetic field generated by moving charges. It touches on theoretical aspects of gravitation and the concept of gravitomagnetism.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants propose that moving masses do create a very tiny gravitomagnetic field according to current theory.
  • One participant questions the basis of the claim regarding "current theory" and seeks clarification.
  • Another participant references the historical development of the concept by Lense and Thirring in 1918, linking it to Einstein's Theory of General Relativity.
  • The term 'gravitomagnetism' is mentioned as a popular term that refers to a linearized version of General Relativity.
  • One participant expresses interest in the topic, indicating they read about it elsewhere.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence or implications of a gravitomagnetic field, and the discussion includes both support for the concept and requests for clarification on its theoretical basis.

Contextual Notes

The discussion includes references to historical theories and terminology, but does not resolve the underlying assumptions or the mathematical framework involved in the concept of gravitomagnetism.

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.
