The black hole is considered an invisible object as it absorbs almost absolute light, but humans once again turn the impossible into possible.
The black hole is a region of space-time where gravity reaches its maximum, causing everything to be drawn in, including light. So to this day, despite its existence by default, science has not yet been able to observe the mystery that scientists call the “monster”!
Black holes remain invisible to scientists
Einstein’s general theory of relativity predicts the existence of a black hole when a mass of matter or object that is in a very small range turns into a black hole, for example, the gravitational collapse of big stars.
Because of the tremendous gravity, a black hole, like its name, resembles a bottomless pit where all matter (planet, star, light …) surrounding it is sucks in without a path. Then increase the mass for black holes, turn them into “cosmic monsters”!
In 1921, Albert Einstein made a name for himself in the physics world after receiving the Nobel Prize in Physics, but not by relativity (published in 1905 and 1915) in connection with his greatness.
Gravitational wave detection reinforces Einstein’s general theory of relativity
Due to the controversy of the physics of this theory, the Nobel committee awarded Einstein for his contributions to physics and the interpretation of photonics.

The cause of many doubts about the correctness of relativity because it is a great revolution, that the ideas of Newton’s classical physics rooted in the scientific world may soon be subject to flip over.
It is also due to the fact that the scientific level of science did not allow scientists to verify, measure or experiment to confirm the theoretical correctness of this new theory.
In the same year, Einstein made his first trip to New York and presented lectures on relativistic theory at Columbia University and Princeton University. He began to attract the attention of the scientific community of his research.
In his book The Formative Years Of Relativity: The History and Meaning of Einstein’s Princeton Lectures (Princeton University, By Jürgen Renn) Physicist Hanoch Gutfreund and historian Jürgen Renn proclaimed the lectures as a “modified version” of general relativity.
In it, gravitational waves are what Einstein predicted from his doctrine, but then, nobody and even he can verify. To this day, 14/09/2015, science and the world can first test this wave.
After the Advanced LIGO scientists grasped gravitational waves after the collision of two black holes and merged together, the whole world is shocked by what Einstein predicts in his relativistic doctrine, reinforcing the belief in the correctness of scientific doctrine.
Accordingly, this type of wave occurs and propagates when gravitational sources have variable variations (and are large enough to produce oscillations such as two interacting black holes, binary systems, neutron stars, white dwarf, thus creating the change of space-time.
Einstein does not believe that humans can find gravitational waves.
Physicist John Archibald Wheeler said: “The object will determine the curvature of space – time; space – time will determine how the object moves“. A reciprocal interaction between space-time and objects within it.
The larger the object, the stronger the interaction with space-time, the more visible the gravitational wave. That’s why it takes us a long time to see the rare phenomenon (two black holes merging together) and find gravitational waves.
The equation Einstein uses in his theory is similar to the equation in electrodynamics, if you take a negative area and accelerate it, you will create an electromagnetic wave (such as radio waves, microwave waves, visible waves, etc.).
In Einstein’s case, if you accelerate a large object, it will create gravitational waves that propagate in space-time as well as the waves that spread all over the ocean!
Scientists will use gravitational waves to observe the “invisible”
This new discovery not only reinforces the accuracy of Einstein’s general theory of relativity but opens up a new horizon in both astronomy and physics as a springboard for the advancement of astronomy.
Because black holes can produce gravitational waves, so scientists now have been able to use gravitational waves to observe black holes. (which is known to be invisible because it absorbs almost absolute light).
Observing something that is not observable is perhaps the best thing anyone can do thanks to the discovery of gravitational waves. Black holes as well as dark matter are unsolved mysteries of the universe and are difficult to study.

Observing black holes by gravitational waves opens up new avenues of exploration, a new approach that gives scientists unprecedented discoveries. Studies of theoretical physics show that black holes can become a deep hole.
The deep hole can help the material shift through space-time as it passes through the shortcut (the gate of space-time), so studying and observing black holes could help science verify this hypothesis.
Even Einstein did not believe that humankind could find gravitational waves
Interestingly, in 1916, Einstein himself did not believe the existence of gravitational waves, He wrote, “There is no gravitational wave similar to the light wave”, but only a year later he changed his view and published a scientific paper that first mentions them.
This publication made some misleading calculations but in 1918 he revised and supplemented his theory in an article titled “On Gravitational Waves”, he died in 1955 and could not yet witness the discovery of gravitational waves (2015).
But Einstein probably does not believe that humanity can detect or observe this kind of wave, in the book:
RIPPLES IN SPACETIME: Einstein, Gravitational Waves, and the Future of Astronomy (Author: Belknap Press / Harvard University), Einstein said that “this kind of wave is too small to detect”, and the distances too distracted the reception of the wave.
If you know the magnitude that scientists at LIGO have obtained so perhaps you will understand why this discovery is considered a miracle of man and is the discovery that Einstein does not believe that man can do.

After the two black holes were 36 to 29 times the size of the Sun, they collided and merged, over a distance of 1.3 billion light years to reach the LIGO Observatory, the magnitude that scientists get by … 0.0000000000001 cm, less than a million times the size of an atom!
If the detection of gravitational waves is seen as a “mission impossible,” now observing black holes is the next great miracle. Let’s wait for the answer in the future!
