Imagine you are a completely flat piece on a very flat and very large chessboard. One day he looked around and asked himself: How did I get out of here? How did the chessboard get out of here? Where did it all start? So pick up your telescope and start exploring the world, which is the chessboard.
What do you think you discovered? The fact that your world has a chessboard is getting bigger and bigger all the time. And over time, that is likely to change. The chessboard is expanding in every direction you can look with your telescope. As far as you are concerned, there is no clear reason for this constant increase in size; It seems very simple that this is the nature of a chessboard.
But wait a minute. If this world is getting bigger and bigger and bigger during this time, it means that the more we go back in time, the smaller it gets, the smaller it gets, the smaller it gets. At a very distant time, at the time of the creation of the chessboard, this world was probably so small that we could say it was “extremely small.”
Let’s start from here, right now. In the early days of your world, the chessboard was extremely small and then began to expand. It keeps getting bigger and bigger until one day you decide to figure it out with the telescope you have. All the parts of this world – all the particles that make up you and everything else – were very close to each other at first and then moved away from each other over time.
The world we live in is exactly the same. When astronomers observe distant galaxies, they find that all the components are moving away from each other. It seems that our world has started its work with very small dimensions and its expansion has been key since then. In fact, scientists now know that not only is the universe itself expanding, but that its rate of expansion is constantly increasing. This mysterious event is due to what physicists have called the “dark energy”, although we do not know much about this type of energy.
Astronomers have also been observing something called “cosmic background radiation.” It is a type of low frequency energy that is found throughout space. We also know from estimates that our universe is 13.8 billion years old. So the world we are talking about is far older than humans, and even three times older than Earth.
If we want to go back to the starting point, we come to an event that created our world and is called the “Big Bang” or the “Big Bang” or the “Big Bang”.
Many people think of a huge explosion when they hear the name “Big Bang”, like a bomb that runs out of seconds and explodes. But the Big Bang was not an explosion that would lead to destruction. It was the explosion that became the beginning of our world, and when we talk about this world, we also talk about space and time. Instead of an explosion, it is a series of rapid and continuous explosions, and this event has made the world bigger and bigger forever.
This expansion is different from an explosion, which can lead to things like chemical reactions or strong shocks. Explosions cause the transfer of energy from one place to another, and usually on a very large scale. But during the Big Bang, energy moved along with the expansion of space, and as space expanded over time, it was transported to any point.
When we return to the world that is actually the chessboard, the Big Bang plays the role of the beginning. The beginning is that the chessboard is expanding forever.
It is important to know that “before” the Big Bang, there was no space and no time. For a better understanding, we can go back to the example of the chessboard. The amount of time the clock on the screen shows can be measured, but there is no time before the game starts – the clock did not work at all. And before the game started, the world of the chessboard had no external existence at all and no space. Therefore, saying the phrase “before” in this sense is meaningless at all. Because there was no time before the Big Bang that we could attribute before and after.
Finally, you must understand that the universe is not expanding and becoming something special, because as far as human beings know, the Big Bang was the starting point of space and time. It’s a little confusing, we know.
Astronomers are currently unsure of what led to the Big Bang. We just look at the findings and realize that this is how the world started. We know that the world is very small and then it gets bigger. We also know that all this happened 13.8 billion years ago.
