I read an article mentioning that when two stars orbiting each other they'll produce gravitational waves that can carry away energy into space. These phenomenon increases the speed of the two orbiting ...
What is the relation between the arm length of gravitational wave detectors and the wavelength of target gravitational waves? For example, LIGO detector has 4 km arms and detects waves with 10^2-10^4 ...
I was currently reading about how LIGO works, it uses the basic principle of a Michelson interferometer, and the laser it uses is infrared laser with 1064nm. so from what I know about interference and ...
What measurements and observations of the Hulse-Taylor Pulsar agreed precisely with the predictions of general relativity, and how did these measurements support the theory?
In the course of this very enjoyable press announcement, it is mentioned that inflation can create gravity waves by amplifying gravity fluctuations. I do not properly understand this statement. I ...
Why can primordial tensor perturbations of the CMB be ascribed to gravitational waves? Is this attribution unique, or are there other michanisms that could lead to the ecitation of tensor modes? In ...
