Material Wave might be a less confusing term than 'Gravity Wave' which at least outside of this field sounds like what someone in the field might call a 'gravitational wave'.
Though that too should be subject to re-definition if a better and more easily communicated understanding of the density of space / time / gravity (as we know it today) makes the term outdated.
- dredmorbius 5y ago"Gravity" and "surface tension" refer to the restorative force in the wave. The terms are well established, at least a century old: https://books.google.com/ngrams/graph?content=gravity+wave&year_start=1800&year_end=2000&corpus=15&smoothing=3&direct_url=t1%3B%2Cgravity%20wave%3B%2Cc0 https://books.google.com/ngrams/graph?content=gravity+wave&y... Compression (sound) waves are also material waves, so that term would generate its own ambiguity. We could instead call the more recently detected gravitational waves "spacetime waves". Though I suspect someone might step in and make some observations about EMR in that context.
