Discussion Overview

The discussion revolves around the nature of gravity, specifically focusing on the concepts of gravitational radiation and the interaction between gravity and spacetime. Participants explore theoretical implications, the mechanics of gravity, and the potential energy dynamics involved.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions where the radiation from gravity goes, suggesting it may be damped by spacetime, which raises the idea that spacetime could gain energy.
  • Another participant asserts that gravity is the warping of spacetime and questions the notion of radiation, asking for verification of their understanding.
  • A different participant inquires whether the warping of spacetime occurs due to a transfer of energy, indicating uncertainty about the underlying mechanisms.
  • Another post raises broader questions about the fundamental nature of gravity, including its sources, limits, and whether it can be "refueled."
  • A participant provides a link to a resource discussing gravitational radiation, explaining that it is produced by accelerating massive bodies and is typically undetectable except in extreme astrophysical events. They also describe the properties of gravitational waves and their effects on spacetime.
  • The same participant questions whether the energy associated with gravitational radiation is "stored" in spacetime.

Areas of Agreement / Disagreement

Participants express differing views on the nature of gravity and its relationship with spacetime, with no consensus reached on the questions raised regarding gravitational radiation and energy dynamics.

Contextual Notes

Participants express uncertainty about fundamental concepts and the implications of gravitational radiation, indicating a need for clarification on definitions and mechanisms involved.

maybe someone can clear up a possible misconception of mine,
if a body can radiate gravity where does this expended radiation
go? i have an idea that it is damped out, by spacetime, but then
spacetime would be gaining energy.
 
Astronomy news on Phys.org
I may be wrong, but I always thought gravity is the warping of spacetime. In this case a body doesn't radiate anything it only bends the fabric of spacetime around it. Please verify anything that I am missing.
 
But then again, when spacetime is warped by a body, does the warping take place because of a transfer of energy?

as you can see I'm new at all this so please correct or verify anything questionable.

sorry I can not help you much with your question
 
We All Know The Basic Effects Of Gravity, But What Powers It,
Does It's Fuel Run Out, Can It Be Refueled, Are There Limits To It's Reach?
 
here is a clip,

Gravitational Radiation is to gravity what light is to electromagnetism. It is produced when massive bodies accelerate. You can accelerate anybody so as to produce such radiation, but due to the feeble strength of gravity, it is entirely undetectable except when produced by intense astrophysical sources such as supernovae, collisions of black holes, etc. These are quite far from us, typically, but they are so intense that they dwarf all possible laboratory sources of such radiation.

Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of space-time.

so is this energy "stored " in spacetime?
