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...

By using the same process for researching fusion energy, the scientists studied gravitational waves, which Albert Einstein first predicted in 1916 as a consequence of the theory of relativity. With the disturbances in space-time caused by the movement of dense object, new formulas “could theore...
that is, any gamma rays, x-rays, ultraviolet waves, visible light, infrared waves, microwaves and radio waves. This spectrum of visible and invisible radiation will help them learn about what the celestial object is composed of, how hot it is, how dense it is and how fast it's moving....
Gravitational waves from a near neutron star pair could have the effect of displacing the oceans by about 10 times the diameter of an atomic nucleus -- a seemingly small amount, but quite large if we're talking about all the water in the ocean. Although there are only six known pairs of...
Gravitational Waves 101What are gravitational waves and how are they detected? These ripples in space-time, sometimes caused by neutron stars colliding, were recently recorded in the groundbreaking LIGO-Virgo observation. About Neutron Stars Neutron stars are ancient remnants ofstarsthat have reached th...
The gravitational waves found last year were short compared with the monster waves that could be turned up by what's called Pulsar Timing Arrays.
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...
Gravitational interactions between colliding galaxies could cause several things: New waves of star formation Supernovae Stellar collapses that form the black holes or supermassive black holes in active galaxies So, do galaxies just float around in space or does some unseen force regulate their movemen...
