Gravity Waves from Earth: Detecting from Orbit

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of detecting gravitational waves from Earth while in orbit. It touches on concepts of gravitational force and the distinction between gravitational waves and the gravitational force exerted by masses.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether it is possible to detect Earth gravity waves from Earth orbit.
  • Another participant asserts that the answer to the detection question is "no".
  • A participant references their astronomy professor's explanation about the gravitational force between two masses, emphasizing that while it exists, it is weak and not relevant to the original question about gravitational waves.
  • There is a suggestion to consider how gravitational forces can be measured, referencing the Eötvös gravity measurement, but questioning its applicability to the original query about detection from orbit.
  • A later reply indicates that the gravitational force between two masses is unrelated to gravitational waves.
  • The thread concludes with a note that it is closed, suggesting the initiation of a new thread for more specific inquiries.

Areas of Agreement / Disagreement

Participants express disagreement regarding the relevance of gravitational force to the detection of gravitational waves, with no consensus reached on the original question of detection from orbit.

Contextual Notes

The discussion highlights the distinction between gravitational force and gravitational waves, but lacks resolution on the original question posed.

Could we detect Earth gravity wave from Earth orbit?

The answer to both questions is "no".
 
My astronomy professor says you and me exert a gravitational force on each other from across the room. It may be very weak and we don't pull together but because of mass it's there. His words.

That is true, but it also is completely irrelevant to the question that you asked in the first post and Vanadium 50's correct answer to that question. You might want to stop for a moment and consider how we would detect the gravitational force between you and your professor (it's there, and if you google for "Eotvos gravity measurement" you'll see how we can measure it)... then consider whether this would work from Earth orbit because that was your original question. And in any case the force between two masses has nothing whatsoever to do with gravitational waves.

This thread is closed, but you can start a new thread with a more specific question when you're ready.
