For thousands of years, people have been surprised by the starry sky. On a clear night, a person cannot help but be amazed by the beauty and majesty of the stars that can be seen.
Those who think about what they see often ask themselves: what is "over there"? How is it organized? Does it end? Where is he from?
In search of the universe
Today more than ever, the universe is known. Over the past decades, all kinds of tools have been invented to help researchers find the answers to their questions.
There are now more powerful optical telescopes that can be used to observe and photograph the stars. Larger and newer radio telescopes collect radio signals from space. And now, advanced tools capable of analyzing starlight and heat are widely available.
In addition, scientists have radar and artificial satellites. They are useful for studying our nearby solar system, ie H. Our sun, planets and moons.
A wave of information has emerged from all of these sources, along with the resulting theories. And a lot of things became clear. The first is that the universe has turned out to be much more incredible than anyone could have imagined, which makes your mind spin when you consider the vastness and complexity of everything. According to National Geographic magazine, what humans are now learning "surprised" them.
He also shattered many earlier theories about the universe. As Geographic said, "The exciting new information that is now circulating all the time is destroying our ideas about the universe."
However, sometimes new information is used as the basis for a new theory that may not come close to the truth rather than what it replaces. Dr. James Van Allen of the University of Iowa recalled what someone once said: “There is something fascinating about science. You will get a total return assuming a negligible actual investment. ""
Another thing that is revealed is how little scientists know about the universe. However extensive their observations, photographs, and recordings, they realize that humans have only scratched the surface of spatial knowledge. It should humiliate us all and increase our respect for the creator of such a fantastic event.
Fantastic dimensions
About fifty years ago, astronomers photographing the sky noticed cloud-like nebula formations on their photographic plates. The gas clouds were considered close. But as larger, more precise telescopes were designed, "gases" turned out to be something much bigger and more meaningful: galaxies.
A galaxy is a large rotating group of stars, gas, and dust. Galaxies are called "island universes" because each is really like a universe. The earth, the sun and the other planets in the solar system are a small part of our galaxy called the "Milky Way". This name comes from the Greek word galaxies, which means "milky way".
Our Milky Way is medium in size. However, it is huge and contains around a hundred billion stars as well as the planets of our solar system and other materials such as gas and dust. Its diameter is so large that if you could travel at the speed of light of 186,282 miles per second, it would take you 100,000 years! How many miles are you doing? Since light travels about six trillion kilometers in a year, multiply that number by 100,000 and you get the answer: Our galaxy is about 600 square miles in diameter! It's number six followed by seventeen zeros.
It is almost impossible for the human mind to understand these dimensions and distances. Yet this is only the beginning of what is “out there”. This is all the more surprising: so many galaxies have now been discovered that they are "as common as grass". The current estimate of their number is one hundred billion. No, not a hundred billion stars, but a hundred billion galaxies! And each of them contains billions of heavenly bodies.
An idea of the number of galaxies can be found in a report published by scientists using the huge 200-inch Hale telescope at Mount Palomar, California. They scanned space as far as the telescope could see, beyond the small area bounded by the Big Dipper. How many galaxies did you find there? Next time you're out on a clear night, check out the Big Dipper Bowl. Keep in mind that about one million galaxies have been found in space beyond this small area!
Have scientists been able to identify the "end" or "outer limit" of the universe in all your research? No, not them. Although they have penetrated more and more into space with increasingly powerful tools, they cannot see the end of the amazing vast sky. But they learned something unique about galaxies.
Clusters of galaxies
The billions of galaxies are not randomly scattered, as if they were randomly thrown into space. Instead, they are organized into groups called "clusters". Thousands of these groups have already been observed and photographed.
Some clusters contain only a few galaxies. For example, our Milky Way is located in a cluster of about twenty galaxies. Within this local group, there are two galaxies closest to us after 200,000 light-years, both named after the discoverer Fernando de Magallanes. Another "close" neighbor can be seen on a clear night without a telescope in the constellation Andromeda. It is a spiral galaxy like ours, about three million light-years away.
Other clusters consist of thousands of galaxies. One of these clusters, about 100 million light-years from Earth, is on its way to the Coma Berenices constellation. This cluster consists of about 10,000 galaxies!
The distance between galaxies in a cluster can vary from a few hundred thousand light-years to a few million light-years. However, the distance between the groups can be hundreds of times greater.
Problems for many researchers
The size of the universe is truly impressive. But also the unique arrangement of galaxies and galaxy clusters. Such an excellent organization suggests an organizer. In addition, all these celestial bodies are subject to definite physical laws. This is what a legislator suggests.
These things disturb evolutionists and atheists. They feel that the universe "evolved" on its own without an organizer, legislator, and life-giver.
However, this is contrary to common sense and our experience. Everything that is organized has an organizer. Every team has a legislator. All living things on earth have a father. Should not the much more complex organization and laws of the universe and life on earth have an organizer, legislator, and life-giver?
