So gravitational waves are a part of that story. Gravitational waves are the idea that that shape of space-time can move from one place in the universe to another. KALOGERA: Gravitational waves were predicted by Einstein just a year after he'd developed his amazing, counter-intuitive, unexpe...
How Real are Gravitational Waves?IN June this year, there was great excitement at the report in Physical Review Letters (22, 1320; 1969) that Professor J. Weber had finally succeeded in the detection of gravitational waves (see Nature, 222, 1117; 1969). . 1969 Nature Publishing Group...

If the recent discovery of gravitational waves emanating from the early universe holds up under scrutiny, it will illuminate a connection between gravity and quantum mechanics and perhaps, in the process, verify the existence of other universes
Neutron stars can have a resounding impact around the universe. Scientists recently announced the first detection ofgravitational wavescreated by twoneutron starssmashing into each other. 1:33 Gravitational Waves 101What are gravitational waves and how are they detected? These ripples in space-time, ...
Gravitational waves are fluctuations in the fabric of space-time caused by the motion of matter. Violent events in the universe, such as two black holes colliding, produce these ripples that propagate through space at, or near, the speed of light. They travel much like a wave, stretching and...
Gravitational Waves: Did Merging Black Holes Form from Single Star? 'New Era' of Astrophysics: Why Gravitational Waves Are So Important Laura Cadonati, deputy spokesperson for the LIGO Scientific Collaboration, who also spoke at the news conference, used a similar analogy when describing what it...
The wave size is dependent on the wind speed generating it. A certain wind speed will only be able to generate a wave of certain size. Once the largest waves that can be generated for a given wind speed have formed, the seas are "fully formed." ...
I give an answer to the frequently asked question of the article's title, based on an analogy between the description of gravitational waves in the transverse-traceless gauge and the description of an expanding universe in comoving coordinates. Both use freely falling masses to define the coordina...
