Sound and discovered gravitational waves yesterday – the Nation (Argentina)

The scientists who made the historic announcement yesterday, to test Albert Einstein’s theory, now allow to lower the sound to sound as ringtone on the phone

a day after US scientists announced yesterday that LIGO observatory directly verified the existence of gravitational waves that Albert Einstein predicted a century ago

the American experts observatory laser interferometry wanted commemorate the discovery creating three mobile ringtones with the sounds they make these waves.

“We want anyone to turn your phone in a machine gravitational waves, “scientists have explained on the website of LIGO, where you can download the audio.

the three audios are entirely composed of the sound waves do when they are detected. Gravitational waves are very similar to the sound frequency, so scientists have moved one frequency to another to create these sounds.

These waves are produced when masses are accelerated and compressed and stretched space. They propagate in a vacuum at the speed of light and distort spacetime, similar to the waves that produces a stone thrown into the water. This applies, for example, what happens to the explosion of a star at the end of his life.

Scientists can exploit these waves as signals from the universe and expect serve to make new discoveries in space. So consider that this is a new era for astronomy

The milestone LIGO is twofold. It is the first direct detection of gravitational waves and the first observation of the merger of a binary system . black holes

the expected discovery coincides with the centenary this year, the publication of the article in which Einstein predicted the existence of gravitational waves as a result of the Theory of General Relativity which was presented in November 1915, just months before.

This discovery confirms the last major prediction of Albert Einstein, it is made possible by LIGO, a large optical instrument that can identify equivalent to one ten-thousandth the diameter of an atom changes, ever more accurate measurement achieved by a scientific instrument.
