Scientists have proven the existence of gravitational waves

A century after the proposals of Albert Einstein, scientists first discovered gravitational waves near large astronomical objects.

NASA's powerful telescope found not one, but as many as 10 super-large black holes. And this is not by chance. The discovery was made by dual LIGO interferometers on September 14, 2015 in the area of ​​Livingstone, Louisiana, Hanford, Washington two days after the increase in the overall sensitivity of the system.

Einstein believed that radio waves, like visible light, X-rays are other forms of electromagnetic radiation. The most active objects in the Universe are two black holes that can crash if something causes the slightest slight fluctuation of space and time.

After decades of failed attempts, scientists made and confirmed the first measurement of gravitational waves passing through Earth.

Since all vibrations before earthquakes distort the rays, the laser observatory of gravitational waves used two sensors (interferometers) for measurements, which are at a distance of 1,865 miles from each other. Since gravitational waves travel at the speed of light, it may take a little longer to detect them from space. Scientists saw on the obtained images a pair of black holes at a distance of 1.3 billion light years from Earth. They approach each other in order to create a new single black hole. An astronomers conference on this will be held this Thursday.

In addition to proving that gravitational waves exist, it has been said that black holes have two stable states.

“Our theoretical predictions relate directly to the measurements of experimenters — a fascinating confirmation of the general theory of relativity,” said astrophysicist at Cornell University.

Black holes are about 29 and 36 masses of the Sun. Their merging will create a new black hole of approximately 62 solar masses.

The European Space Agency launched a pioneering satellite in December to test equipment for fishing for a longer ripple of waves in space.

“The colliding black holes created a strong storm in the tissues of space and time,” said KipTorn, a physicist at the California Institute of Technology.

The storm lasted only 20 milliseconds, but during this time it “absorbed” more objects 50 times more than all the stars in the universe, Thorn added.

“You get electromagnetic radiation — mostly light — by moving these charged particles. This is the same idea with a radio mast in which electrons go down the antenna. If you move the whole mass instead of moving a part, you will get gravitational waves, ”added NASA astrophysicist Ira Thorpe from the Goddard Space Flight Center in the Green Zone, Maryland. The longest gravitational waves were produced during the Big Bang 13.8 billion years ago. Colliding black holes are the strongest gravitational space objects.

The discovery on Thursday, which is described in more detail in an article in Physical Review Letters, opens the door to a completely new, previously unknown branch of astronomy.

“The frequency of these waves is in the range of human hearing. If we can hear these gravitational waves, then we can hear the Universe. This is one of the most amazing things. We are not only going to continue to observe the universe, we will listen to it, ”said physicist Gabriela Gonzalez of the University of Louisiana.
