Many articles and books describe in excellent scientific and technical detail the extraordinary developments and results of the gravitational waves research that took place in the last decade and resulted to the award of the 2017 Nobel prize to Reiner Weiss, Barry C. Barish and Kip S. Thorne "...
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, ...
The recently launched LISA Pathfinder will detect and study gravitational waves in space. by Sarah Sloat Dec. 4, 2015ESA Rejoice all you visual learners: If the physics behind the workings of gravitational space waves, a.k.a. ripples in spacetime, is a head-scratching topic, the European Sp...
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...
usinggravitational wavesemitted by a relatively rare system: a black hole-neutronstar binary, a hugely energetic pairing of a spiraling black hole and a neutron star. As these objects circle in toward each other, they should produce space-shaking gravitational waves and a flash of light when the...
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...

This is the first time scientists have seen gravitational waves and light waves from the same event. Studying the universe with these two fundamentally different types of information is like observing the world with multiple types of sensory input, such as vision and hearing — it offers the poss...
Gravitationalwaves are the gravitational field of wave form and finite velocity propagation.Although Einstein in 1916 predicted that the quality of the acceleration wavesmay exist, but he proposed gravitational wave is associated with the selectionof coordinate, in a certain frame of reference point of...
