Thousands of superlative lenses are present in the universe, this mystery can be solved
Scientists have detected a large number of gravitational lenses using Artificial Intelligence.
Telescopes are used to learn about astronomical objects. There are many types of telescopes. But do you know that the universe already has many natural telescopes. Yes, the universe's galaxies and other giant objects act as a lens for distant objects. A recent research has found hundreds of similar lenses using Artificial Intelligence technology. Their effect is called Gravitational lensing.
What is the gravitational lensing effect
It is a natural phenomenon when a large amount of matter, a large galaxy or group of galaxies, creates a gravitational field and magnifies the light passing through it. But this happens without changing the sight of the bodies behind those giant objects. And this effect is called gravitational lensing.
Einstein first gave its concept
The concept of gravitational lensing was first introduced by the great scientist Albert Einstein a hundred years ago. This can explain how light turns when it passes through very heavy bodies, such as the Galaxy or Galaxy group.
What do these gravitational lenses work for
Are like a natural and cosmic lens. These lensing effects are of two types. One weak and the other strong. The power of a lens is related to the location of an object, its weight (mass or mass), and the distance from the source of light of the lens. The weight of a powerful lens can be one hundred billion times greater than our sun, which will divide the light coming from the same path and coming from more distance so that we can see more than one picture or different rings or arcs.
At first such lenses were seen very rarely, but ...
The problem with powerful lenses is that they are rarely seen yet. After appearing for the first time in 1979, he has seen only a few hundred. But now the situation is changing. Earlier this month, a team of international scientists have found 335 new powerful lensing contenders from a study conducted in the Astrophysical Journal. For this, he used data from the US Department of Energy-backed Arizona project called the Dark Energy Spectroscopic Instrument (DESI). In this research, he also took help of the winning machine learning algorithm of an international science competition.
Senior scientist David Schlegel, who participated in this research, believes that finding such items was like finding a telegraph scope the size of Glaxy. They can be powerful tools in finding dark matter and dark energy. These gravitational lenses can be helpful in obtaining specific information, such as these can give special symbols to estimate the exact second between different galaxies.
These lights can be put on dark matter
Most hope from them is that they can act like a window in giving information about the non-visible dark matter. Currently, scientists believe that 85 percent of the universe is dark matter. It is believed that dark matter is more and more responsible for this lensing effect. Dark matter, the rapid expansion of the universe caused by dark energy, is one of the mysteries that physicists are looking for.
Study of data with the help of supercomputer
The researchers studied the data with the help of a supercomputer and divided the strong lens contenders into three categories according to their power. These claimants were helped by the Neural Network, a program of specialized artificial intelligence which identifies these claimants. For this, the researchers arranged thousands of photographs and gave them to the computer program so that it could identify the claimants in hours.
Competition started
Work in this kind of data mining is becoming very complex and huge because the amount of data is also increasing rapidly. The event started with a competition. Many researchers are also interested in participating in such programming challenge competitions. The members of the latest research now aim to find 1000 strong lenses.
