gravitational waves are ripples in the very fabric of the Universe; disruptions in space-time* that can only be detected by the most sensitive instruments around
Gravitational waves are ripples in space-time produced by the accelerating motion of something that can feel the pull of gravity. Because gravity is a weak force, an object needs to have a whole lot of mass crammed into a small volume to create big enough space-time ripples to detect. Gravitational waves are ripples in the metric of space-time caused by accelerating mass, so they can carry information about the motions of astronomical objects. On September 14, 2015, the detection of gravitational waves by Advanced LIGO (aLIGO) was a dramatic confirmation of Einstein’s General Theory of Relativity.

The biggest gravitational waves would only cause the 2016-02-11 According to his theory of general relativity, the force of gravity is the result of curvature in this space-time: gravitational waves are ripples in it. The ripples are produced by accelerating If mass distorts space-time, then mass under acceleration must create ripples in the space-time. As if you toss a stone in a pond it will create waves that ripple out across the water’s surface. Similarly, massive objects accelerating in space-time will create waves that ripple out across the universe at the speed of light these are called gravitational waves. In the moments immediately following the Big Bang, the very first gravitational waves rang out. The product of quantum fluctuations in the new soup of primordial matter, these earliest ripples through the fabric of space-time were quickly amplified by inflationary processes that drove the universe to explosively expand.

This marks the first time that a cosmic event has been viewed in both gravitational waves and light, with profound implications for our understanding of the cosmos. Scientists might have discovered the first signs of the gravitational-wave background: a sea of ripples in space-time reverberating throughout the universe.

Kategorier: Matematik och naturvetenskap Naturvetenskap. On 14 September 2015, after 50 years of searching, LIGO och observationen av gravitationsvågor från kolliderande svarta hål för några år sedan, Ladies and gentlemen, we have detected gravitational waves! A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space.
