Dear Editor,
In this era of advanced technology, research and discovery about earth and the universe has been going on for many decades. Despite this, scientists say that there is much that remains to be discovered. Meanwhile, scientists know a lot about their world, but now they have gradually become convinced of a world which is completely opposite to our world. About fourteen billion years ago there was no universe, only darkness. Suddenly a point arose. Then that point started rolling in. The explosions started inside the point itself. Then due to the mutual collision of protons inside, immense energy was created. The explosion turned into a big blast. The universe continued to be created from these great explosions. Even today, great explosions keep happening in the universe. In this way the universe is continuously expanding. This is the Big Bang theory. The universe is constantly expanding and the speed of its expansion is accelerating. All the planets and stars and galaxies are moving away from each other. This mystery has been unsolved for the last two decades as to what is it that has led to this expansion.
It continues and its pace is accelerating. Scientists are trying to understand the speed of this expansion in a number of ways, which can help them find answers to many unresolved questions such as the age, structure and expansion of the universe. Astronomers at the University of Chicago have suggested a new method for understanding the evolution of the universe called spectral sirens, in which they can understand the ancient universe through the collision of black holes. It is said about the black hole that it is a place where information also disappears, yet scientists have found many Through these indirect methods, it has been successful in extracting such information, which can be known about the history of the universe. In a new study, two astronomers have developed a method by which pairs of colliding black holes can be used to measure the speed of the expansion of the universe. This will allow us to know from where our universe evolved, from what it was formed and where it is going. What is the rate of expansion of the universe; this remains the biggest question and the subject of debate. The new study proposes a new method of this calculation, in which the celestial vibrations produced by the collision of black holes can be measured by special detectors. When two black holes collide, they everywhere in the universe, a vibration spreads in ‘Akash-Kal’. On Earth, the Laser Interferometer Gravitational Wave Observatory in US and Vargo Observatory in Italy can capture these vibrations, which are called gravitational waves. Over the years, LEGO and Vargo have collected data on collisions of about ten black hole pairs. The information about the mass of the black hole is hidden in these waves. But due to the expansion of the universe, the properties of these waves change along the way. If scientists can measure the change in these waves So they can also find out the rate of expansion of the universe. Scientists are still engaged in the discovery of what dark matter is. It is believed that ninety-five percent of space is made up of dark matter and dark energy. Dark matter acts as an attractive force, a kind of cosmic mortar, that holds our world together. This is because dark matter interacts with gravity, yet does not reflect, absorb or emit light. Dark energy is a repulsive force, a type of anti-gravity, which Slows down the expansion of the universe. It is estimated that about twenty-three percent is dark matter. Antimatter has no power at all, but dark matter is everywhere. According to scientists, dark matter and dark energy are the only link, which has tied this entire universe in an orderly manner. Dark matter is made up of substances that neither emit, absorb nor reflect light. For this reason it has not been possible to see it yet. Scientists discovered dark matter. But they could never gather correct information about it. It turned out that all the galaxy’s planets, stars and constellations are stable due to the binding force of gravity. But on calculation it was found that the gravitational force is not enough to hold the galaxy. Meaning there is some other unknown thing, which is holding them. Otherwise, the gravitational force would have weakened by now and all the planets, constellations, stars would have deviated from their orbits. This thinking gave strength to the concept of dark matter. Dark matter itself Giving mass to this universe. In this era of advanced technology, research and discovery about the earth and the universe has been going on for many decades. Despite this, scientists say that there is much that remains to be discovered. Meanwhile, scientists know a lot about their world, but now they have gradually become convinced of a world which is completely opposite to our world. This theory is explained in detail in the journal Annals of Physics. Researchers also say that in this world. The neutrons would be moving from the right side. To prove the point of this world, scientists are testing mass neutrons. If they succeed in this project, then it will be proved to be a thing of the other world. Scientists also do not rule out the possibility that like our world, there is a world where the wheel of time moves in reverse.
Vijay.
