Developing space science and technological development!

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 approximately equal to the distance of 1.56 lakh light years.  And millions of such galaxies are spread 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 that the Milky Way and the Andromeda Galaxy are moving towards each other at a speed of about 200 kilometers per second.  Which after the next 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.  However, many scientists do not fully agree with this new information and for reasonable reasons this theory may not be correct.

But in any case, this vast universe full of immense wonders will probably remain a very mysterious and fascinating subject for mankind forever.  Until then, none of our generation may 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 survive or reach the stage of Type Two civilization.

Currently, countries like America, China, European Union, Russia, India, Japan, South Korea are progressing smoothly in the competition of space science and technological development, but the smooth participation and contribution of the countries of the Muslim world with a population of 1.8 billion in the space conquest journey is not the same.  Although there are 60 Muslim majority countries in the world, these countries have not been able to take a worthy place in science and technology development.  Therefore, the contribution and capacity of the countries of the Muslim world remain at a disappointing level when considering the new system innovations and technological capabilities of the modern era.

However, in more recent times several countries in the Muslim world such as Turkey, Iran, Malaysia and Indonesia have made great strides in economic development and several sectors of technology.  However, to meet the challenges of the 21st century, especially in space science and research, we must try our best to keep up with the developed world countries.  And to implement this goal, we must first of all build the country's education system, especially a modern and world-class education system based on real-life science and technology, and a modern or world-class research field.
