gravity wave

[′grav·əd·ē ‚wāv]
(fluid mechanics)
A wave at a gas-liquid interface which depends primarily upon gravitational forces, surface tension and viscosity being of secondary importance.
A wave in a fluid medium in which restoring forces are provided primarily by buoyancy (that is, gravity) rather than by compression.

It may take months of data analysis to separate out a gravity wave signal from thumps generated by the nearby construction and traffic, but when it happens, it will be party time at LIGO.
Variations in the regularity of the pulses could be the tell-tale sign that a pulsar has been tossed about by passing gravity waves.
The two separate LIGO installations, 2,000 miles apart and costing $160 million each, are necessary to make sure the telescopes actually detect gravity waves from space--not Earth.
You'd think a book with a title such as this would begin with a review of basic principles of natural law and the nature of scientific inquiry, and gradually build to advanced notions, Instead we dive right in with five pages on Newton's Principia, then leap immediately to four pages on gravity waves, a speculative concept from astrophysics that makes for entertaining ruminations, but which is pretty far afield from "what everyone needs to know" about science.
In contrast to the conventional theoretical approach to stellar evolution, the data-driven approach of MAMSIE will allow us to include angular momentum transport due to internal gravity waves, as well as mixing prescriptions for turbulent entrainment, from coupling of the output of 3D hydrodynamical simulations of these phenomena to specialised seismic observables of relevance for massive stars.
The observation itself isn't Earth-shaking as researchers know that these particular swirls or "B-modes" originated in conventional astrophysics, but the result suggests that scientists are closing in on a much bigger prize: B-modes spawned by gravity waves that rippled through the infant universe.
It is these cancellations that could allow gravity waves to permeate through both intense quantum fields as well as the assumed vacuum of general space.
He directs this presentation of the physics and math describing internal gravity waves to students with some background in multivariable calculus, ordinary differential equations, and partial differential equations (useful, but not necessary).
From probing the inner workings of molecules to detecting gravity waves from deep space, lasers remain today a vital tool in the advance of science.
So far, the university has been awarded 34 grants for everything from summer lab programs for undergraduates to continuing the search for gravity waves.
