LIGO and speed of gravitational waves

  1. Jun 29, 2004 #1
    LIGO may have failed to detect gravity waves because they move faster than light and so have a greater wavelength than expected and probably a lower amplitude too.

    Gravity waves and the speed of light.

    Gravitatioonal waves travel at not in excess of the speed of light. They know that gravitational waves traveling at the speed of light shows a unity of gravity and electromagnetism at a deeper level (high energies).

    How do they know this?What is the evidence?

    I'm fairly certain that the reason LIGO has not yet detected gravity waves (definitively), is because it is still in the process of taking its measurements. The results will not be known for sometime yet.

    Give LIGO more time. It's just getting underway at trying to find something incredibly difficult to detect.

    And a way in which to process this information?

    They have no way of knowing computationally how to describe the actions of the flexing in terms of Geometrical explanations?

    "the actions of the flexing in terms of Geometrical explanations"???

    They sure have a lot of expertise and resources for computation in GR. GR may not be the ultimate theory of spacetime, but it sure has been bang on in many predictions.

    Yes I agree with you. If there was a method in place for describing quantum Gravity, you can be assured the first part of my statement would have been relevant to the second part you choose. Looking at the various experiments being used how could I not Support GR even though we have not validated gravitational waves.

    Would you agree with this?

    Well I'm not a physicist, but as an amateur I would have a question.
    Isnt the correct way to prove something, that we examine assumption A and assumption B, which validates the measurements better?
    I think if we wants to validate assumption A /gravity waves can only propagate with a speed of c/ anyway, we can make same error during the process.

    (Like Hafele–Keating experiment, i dont doubt that predictions of GR has been proven many times, but i dont think, that an experiment, where they correct the clocks multiple times till they get what they want... isnt a solid proof to me.)
