Einstein was right!

Einstein was right!

It needs the Nobel prize. US-researchers from the LIGO Observatory have announced that for the first time gravitational waves beobachet. A great Moment for science and for the net.

To this message the world has hingefiebert – and yet they are actually no longer surprised. For whatever reason, otherwise you would have a press conference in Grand style, announced, if it is not a Sensation would be…? Right.

You can see the scientists at the National Press Club in Washington the joy. So much So, they also try to seriously act in the Team of the Laser-Interferometer-gravitational-wave Observatory, LIGO, the Smile not from the lips.

After a short greeting comes to the US-American physicist and LIGO Director David Reitze quickly
to the point: “Ladies and gentlemen, we have detected Gravitational Waves. We did it!”

14. September 2015, the scientists had the two colliding Black holes measured, the key information provided. Then it would have took months, says Reitze. You would have to validate the data and reviewed in order to ensure that it really is a gravity wave.

This is one of the most spectacular confirmations of Albert Einstein’s theories, which was still open. The fact that gravitational waves exist and the ability to directly measure, a fundamentally new tool for the exploration of the universe, emphasized Alessandra Buonanno, Director at the Max-Planck-Institute in Potsdam. “This starts with security, a new Era in physics and astronomy.”

And so, there is certainly also a new candidate for the Nobel prize in physics, such as DW reporter Brigitte Osterath, the press conference had said.

It seems you are not alone. The entire network seems to be of the gravity wave to ride.

This is not light fare. Gravitation, Einstein’s theory of relativity, space-time – what lies behind it, are probably only a few people understand, let alone explain.

In brief: Every accelerated body emits gravitational waves, so a motorist at a traffic light starts. The waves are all the stronger, the more mass the body has.

However, they are usually so tiny, that Einstein himself is not believed that they ever could measure.

About as tiny as the Signal, the frequency of a Gravitational wave will be generated, if you are caught. The scientists demonstrate this at the press conference – a short “Chirp”.

According to the analysis, the two had observed Black holes 29 and 36 Times as much mass as our sun. From their merger, the Black hole, however, has only 62 times that of the sun. The difference of 3 solar masses is in accordance with Einstein’s mass-energy Equivalence in the Form of Gravitationswellenenergie radiated. The LIGO scientists describe their discovery in the prestigious journal “Physical Review Letters”.

Again lucky

Already in September, the American physicist Lawrence Krauss of speculation on the net fueled.

This was, however, quickly DISCLAIMED. The LiGO researchers but did not want to because of a message that may be as wrong turns, make speeches. Now Krauss, however, right – and we should be excited, as the next Nobelpreisvergabe out.
