A fluctuating gravitational field keeps Io http://www.nasa.gov/multimedia/imagegallery/image_feature_758.html volcanically active. What, then, is the basis for believing or assuming that gravitational waves will traverse solid matter without being absorbed and turned into heat?

If you go to the BOINC project from Berkeley you can participate in the Einstein at home project that is a grid computing project calculating data for the Ligo project.

Very intriguing and educational. You put that togetger very well.

If you still don't "GET IT" then I suggest you post over on the BAUT forums so you can get a more articulate response than is possible in this forum.
G'Luck!!!

To RapideEye:
It is agreed that an undulating gravity wave could have a detectable front or back edge. But not necessarily so. If the LISA detector is based on edge to edge measurement and I believe it is, it may not respond to a passing wave because of its dc nature. My sense on gravity wave distortion of matter is that any measurement of anything inside a segment of or the whole of a gravity wave might be fruitless. I think the info link between the two LISA detectors will also be stretched and compressed in step with the matter in the region the wave is passing through. There doesn't appear to be a reason to think the info link between detectors will not also be stretched and compressed resulting in no measurement. I don't see how there could be any exclusions in gravity wave distortion.
