Gravity Wave Measurement: Measuring the Relative

Click For Summary

Discussion Overview

The discussion revolves around the measurement of gravity waves and the potential effects of strong electromagnetic (EM) fields on laser light and space. Participants explore the relationship between forces, space warping, and the implications for gravity wave measurement.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question whether it is possible to measure something relative in the context of gravity wave measurement.
  • There is a claim that an alternating EM field will not change the laser light, although this is debated.
  • One participant wonders if a very strong force could change space without affecting the laser or light, suggesting that gravity is simply a type of force.
  • Another participant argues that an intense EM field could warp space similarly to gravity and that the mass of the EM field could contribute to this effect.
  • Concerns are raised about the potential for an intense EM field to affect the performance of laser devices, which could complicate measurements.

Areas of Agreement / Disagreement

Participants express differing views on the effects of EM fields on laser light and space. There is no consensus on the implications of these effects for gravity wave measurement.

Contextual Notes

Participants have not fully resolved the assumptions regarding the strength of forces and their effects on space and light. The discussion includes speculative elements about the conditions under which these effects might occur.

Hi, here is my thinking about the gravity wave measurement. Could we actually measure something relative?

Yes that is truth. But I am wondering if a force that is very strong, could it change the space but does not change the laser or light? like squeeze it or extend it.

Because for the gravity, it just a kind of force.

In the extreme, the EM field has a mass and therefor gravity. And of course, it would warp space as gravity does. But unless you EM field is powered by fusion bombs, your body would cause more space warping than that EM field.

Also, the EM field could be so intense that the it affected the performance of the laser device itself - and thereby affect the laser beam. But that would be a technical shielding problem.

That is great point, thank you.
