The progress of the most mysterious space science!
Science means the positive change of thinking and the development of new technologies for the benefit of mankind. An idea that seems to be correct in the language of science today, may change the original idea completely with the touch of high technology of the future. There is no room for unnecessary criticism or ridicule. Science is a continuous and ongoing process and will continue to evolve, change and modernize to an extreme extent over the centuries as long as mankind survives.
In fact, at the beginning of the 20th century, in 1922, space scientists estimated that the size or extent of our universe could be from 1 lakh to 5 lakh light years. However, just 100 years later, in the 21st century, in the year 2024, scientists began to present new and surprising information about the size of the universe to the data world with the benefit of using high-tech Hubble, Euclid or James Webb telescopes. .
As a result of long-term studies and observations, space scientists now believe that the size or approximate extent of this vast universe may be about 93 billion light years or more. Again, after the next 100 years, around 2124, this idea will change and scientists may say that the size of our universe, surrounded by infinite mystery, will be about 400 billion light years. Which is a long-term, continuous and ongoing process of science. Even at the beginning of the 20th century, scientists mistakenly identified the Andromeda Galaxy as a nebula or nebula in the vicinity of the well-known Milky Way Galaxy.
But today with the touch of high technology we know that the diameter of our Milky Way galaxy can be approximately 84 thousand 700 light years to 1 lakh light years. Whereas the diameter of our neighboring Andromeda Galaxy may be equal to a distance of approximately 1.56 lakh light years. And millions of such galaxies are scattered all over the universe and according to the big frog theory, they are running at their own speed and orderly in their invisible orbits in the infinite space of the universe.
Astronomers have closely studied and found that the Milky Way and Andromeda Galaxy are moving towards each other at a speed of about 200 kilometers per second. Which after about 3 to 5 billion years, these two galaxies will form a new super giant galaxy through a terrible collision or great merger for millions of years. They named it the Milky-Mida galaxy and its size, or diameter, would be about 300,000 light years.
But surprisingly, some space scientists believe that the initial merger process between these two neighboring galaxies has already begun. In particular, they observed some hypervelocity star systems, which are either entering our Milky Way from the Andromeda Galaxy at speeds of 60 to 80 million kilometers per hour, or an unknown number of hypervelocity stars may have already entered. Although many scientists could not fully agree with this new information.
But in any case, this vast universe full of immense wonders will probably remain a very mysterious and fascinating subject for mankind forever. By then no one of our generation will be alive. But finally, our hope is that new technology innovation, research and scientific development should not be used for the production of deadly weapons, but for the welfare of mankind. Otherwise we will never reach the stage of type two civilization.
