Gravitational waves finally proved. The phenomenon of the time-space wrinkles was not only reveal cosmic events, but also reveal the deepest secrets of the universe.
Scientists in Hannover, Germany, were the first to analyze data recorded by a detector in the United States, the gravitational wave. Karsten Danzmann and his team developed and tested the magic wave measurement technique. Whereas the LIGO detector used for measuring the first wave looks simple. Why has it been so hard to detect gravitational waves?
Prof. Karsten Danzmann is director of MPI Gravity Physics at Leibniz University: "The basic idea is simple How can we prove gravitational waves We must measure the shrinking and expanding space And how to measure the shrinking space by measuring its length Just we have to measure the length very accurately, because the style is too small, and the measuring technology using this laser beam has just been in us for the last few years. "
Inside the container is stored heart detector. This installation emits laser light through both long pipes underground. The beam is reflected, then crashed into each other. Should both light waves eliminate each other. But if the light is fluorescent, the cause is probably a gravitational wave.
The first signal of the gravitational wave looks normal, but for Karsten Danzmann this signal is everything. He thinks this wave is beautiful. As described by Albert Einstein. Gravitational waves can also be heard.
More than a billion light years from the earth there are two black holes that whirl together at incredible speeds. About 200,000 kilometers per second. At the time of melting, both releases energy momentum that is 50 times greater than the entire universe.
What's even more surprising is that the most terrifying cosmic event ever detected by humans is total darkness. There are 20 activities to detect the rest of the collision in hopes of finding the signal across the entire spectrum of the electromagnetic spectrum, with radio waves, x-rays, or short waves. But nothing, "explained Danzmann. (Source:dw.com)
No telescope can record the melting of two black holes. Gravitational waves are believed to be opening new windows into the universe. More than 99 percent of the universe is invisible. Therefore scientists develop more sensitive detectors to be able to hear further into the darkness. They even plan space missions.
The mission is in the form of three satellites that emit laser light within five million kilometers. Scientists will oversee the distance between satellites accurately to detect gravitational waves. With that, said Karsten Danzamnn, scientists can hear black holes throughout the universe. And maybe even catch the gravitational waves from the big bang that makes up the universe. But why do scientists want to uncover the secrets of gravitational waves?
Prof. Karsten Danzmann: "To know how everything is created, where it comes from, I do not know, humans seem to be born with a great desire to know everything.Like knowledge of the bloodline It is also useless.But still there are many people who want to know who their ancestors So it's like looking for a cosmic lineage to reveal the secret of the big bang "
Until they can examine the big bang thoroughly, they have to go a long way ahead. Because only in 2028 the space detector they developed could be enabled.
