# For the first time, scientists have directly detected gravitational waves — ripples in space and time — in addition to light from the spectacular

Men det är klart att teamet bakom HST aka Hubble Space Telescope observed ripples in the fabric of spacetime called gravitational waves,

Govert Schilling recounts the struggles that threatened to derail the quest and describes the detector's astounding precision, weaving far-reaching discoveries about the universe into a gripping story of ambition and perseverance. Scientists have wanted to measure gravitational waves ever since Einstein’s prediction. In 1974, astronomers gave us the first indirect evidence for gravitational waves by carefully looking at the orbits of extremely heavy stars. [1, 2] But scientists still wanted to directly measure the gravitational waves themselves. LIGO, or the Laser Gravitational waves are analogous to how a drum head ripples when it is struck with a mallet, or how a pond ripples when a pebble is dropped in it. If you imagine the universe as a stretched out blanket as spacetime, then imagine an object with mass as a blowing ball as matter, you can see how the matter would curve spacetime causing what we Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.

It is possible that gravitational waves—ripples in spacetime—could illuminate dark energy.

## The most powerful gravitational waves are created when massive objects move at very high speeds. This means the significant ripples in the curvature of spacetime are produced when two black holes orbit each other and merge. Moreover, two big stars, especially the neutron stars also give rise to gravitational waves while orbiting each other.

Anything that causes ripples in spacetime is of interest to me. But what is almost more important is the technology that can measure this type of phenomenon.

They stretch and squeeze the space between objects. They are produced when violent events occur in the Universe, such as the orbital motion and merger of two black holes. Gravitational waves - a strange phenomena, first described as the outcome of Einstein’s General Relativity theory, where “ripples” are formed in the fabric of space-time by the movement of very large masses, such as the merging of in-spiral black holes or neutron stars. New research suggests that gravitational waves could help figure out more about the mysterious dark energy thought to be lurking in the void.

Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. Ripples in Spacetime is an engaging account of the international effort to complete Einstein’s project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe’s structure and origin. Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light. They were proposed by Henri Poincaré in 1905 [1] and subsequently predicted in 1916 [2] [3] by Albert Einstein on the basis of his general theory of relativity .

### 3 Oct 2017 American physicists Rainer Weiss, Barry Barish, and Kip Thorne have won the Nobel Prize in Physics for the detection of gravitational waves.
