Mysterious gravitational wave

- Scientists have again measured a gravitational wave. It is the second time that works. Such waves are perhaps the greatest mystery of the universe. Science has for years dabbled and delved, but now it is clear that they do indeed exist. The particular measurement is announced Wednesday at a press conference in San Diego.

The new gravity wave was picked up in the night of first on Boxing Day by advanced sensors in the south and in the western United States. The signal is, in fact, a shock wave that travels through the fibers of the universe.

The wave was sent out at the moment when two black holes fused together. That happened about 1.4 billion years ago. One black hole weighed fourteen times as much as our sun, the other black hole about eight times as much. Together they weigh suns so 22 but the new object appears 21 times as massive as the sun. The one remaining 'solar masses was thrown as energy to all corners of the universe, and now in our area.

There may even measured a third gravitational wave, on October 2 last year, but it is not definitive yet. The scientists need time to revisit after measurement.

The researchers had in February for the first time announced that they had measured a gravitational wave. That came from the merger of two black holes. The wave moved a special laser beam a millionth of a millionth of a millionth of a meter.

Albert Einstein had suggested in 1915 that the universe consists of space and time and that these constitute a whole. After a violent incident can 'spacetime' vibrate. The shock waves, gravity waves, then go through the universe like ripples from a stone in a pond. In such a ripple stretches the space matter whether it shrinks slightly. Only now Einstein the same can be proved, thanks to the most advanced laser equipment.

Scientists can look at the universe with gravitational waves in a whole new way. They see things that remained hidden until now, such as objects that emit no light.

Scientists from the research Nikhef Amsterdam, Radboud University Nijmegen and the Vrije Universiteit in Amsterdam involved in the investigation.
