Las ondas gravitacionales como ondas no lineales gravitational waves as nonlinear waves francisco r. While a black hole merger isnt expected to be observable by other telescopes, and indeed nothing was observed by other telescopes this time, other events that ligo might detect, such as a merger of two neutron stars, may create an observable effect. We can hope for such exciting news over the next year or two. Gravitational waves are perturbations in the theoretical curvature of spacetime caused by accelerated masses.

Gravitational waves carry information about their dramatic origins and about the nature of gravity that cannot be obtained from elsewhere.
Since we discovered the first wiggles in spacetime signifying the distant merger of two black holes, ligo has announced around ten confident detections of gravitational waves from black holeblack hole collisions with the prospect of many more discoveries in the future. Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. The signal was observed with a matchedfilter signaltonoise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203000 years, equivalent to a significance greater.

A gravitationalwave observatory or gravitationalwave detector is any device designed to measure gravitational waves, tiny distortions of spacetime that were first predicted by einstein in 1916. This is a significant step toward a spacebased gravitationalwave detector. Therefore, no doubt, gravitational waves must exist, and be experimentally detectable.
