This is the wave of gravitational shock caused by the largest observable merger of two black holes to date. The signal from the incident reached Earth after travelling nearly seven billion years in May last year, but it was still so powerful that it shook laser detection devices in the United States and Italy.

Researchers say that the collision of black holes has created a black hole that is 142 times the mass of our sun.

This is a very important development. The existence of black holes in the sky has long been known to science, which is either very small in size or very large.

This is a joint analysis of Leo and Virgo international organizations. The two companies jointly manage three highly sensitive systems installed in the United States and Europe to detect gravitational waves.

What is a black hole?

A black hole is a region in space where the matter is extremely dense and concentrated.

Here gravity is so strong that even light cannot get out of its grip.

Black holes are actually caused by the explosive disappearance of large stars.

However, some of them are extremely large in size and billions of times larger than our Sun.

These giant black holes are usually found in the middle of the galaxy and it is not known how they came into being.

Black holes are detected by affecting their surroundings.

When they collide, they produce observable gravitational waves.

Laser interferometers used by Lego and Vergo 'hear' the vibrations in space caused by a catastrophic cosmic event.

On May 21, 2019, all these instruments were shaken by a powerful single that was recorded for only one-tenth of a second.

Computer algorithms found that the signal was generated from the last moments of the integration of the two black holes. One of these black holes was 66 times larger than the Sun, while the other was 85 times larger.

The integration was recorded at a distance of 150 trillion kilometres from Earth.

"It was an amazing event," said Professor Nelson Christensen, who works at the C ڈte d'Azur observatory in France. This signal has been travelling for seven billion years, meaning that it happened shortly before the middle of the universe and has now shaken our instruments on Earth.

Gravity waves: Space-Time vibrate

Albert Einstein's Theory of Relativity predicts waves of gravity.

It took decades to develop technology to detect or detect these waves.

These waves are vibrations in space-time caused by explosions.

Fast-moving matter produces waves that travel at the speed of light.

Of these, however, the Earth's instruments can only capture waves generated by the integration of black holes or neutron stars.

Lego Vergo devices fire lasers into long tunnels in the form of the English letter L. Gravitational waves disturb this light.

By detecting these waves, we can explore the universe in a new way.

The presence of a body 85 times the mass of the Sun in this collision has taken scientists by surprise, as our current understanding of the formation of black holes from the end of the stars cannot explain such large bodies.

In large-scale stars, when nuclear fuel is depleted, their core collapses on their own, creating a black hole. However, according to scientists, the physics within the stars is workable, so it is impossible for this to happen in a star that is 65 to 120 times larger than the Sun. The fading stars that give birth to black holes, in fact, completely wipe themselves out and have nothing left.

If science is correct at this point, it means that a black hole weighing 85 times as much as the Sun may have come into being earlier due to the possible merger of black holes.

And Martin Hendry, a professor at the University of Glasgow in the United Kingdom, believes that this could give a clue as to how the universe evolved.

"We're talking about one integration after another, which could lead to the biggest black holes possible," he said. So do you know that this black hole, which weighs 142 times as much as the Sun, has merged with another very large black hole? We believe that the creation of the largest black holes ends with the largest black holes in the very centre of the galaxy.

Lego Vergo will report the incident on May 21, 2019 (preserved as GW 190521) through two research papers.

One of the studies was published in the journal Physical Review Letters, which detailed the discovery. Another study, published in The Astrophysical Journal Letters, discusses the physical properties of signals and their scientific implications.

GW 190521 is one of the 50 events that are the source of these 50 gravitational waves that are being researched in laser laboratories.

How does this system work?

A laser is sent to the machine and its beam is divided into two parts

These twisted rays collide with the damp mirrors and travel in different directions

Eventually, these rays are reconnected and then sent to a detector

The gravitational waves that pass through the laboratory disturb the system

The theory is that because of these waves, these rays of light must propagate and contract

This should make a difference in the length of the light rays

The photodetector detects this change in radiation
