The universe is indeed very vast and consists of various components. Starting from stars, planets, asteroids, satellites, comets, to black holes.
We ourselves are on Earth which is located in the Milky Way galaxy. The galaxy we occupy is not stationary in its axis, but constantly ventures through the universe, so even if you are silent reading this article, you are actually moving at high speed through the universe.
Planets are composed of minerals and hot substances that are located in the core of a planet. Although each planet contains minerals, not all planets can be inhabited by living creatures, because to evolve into an organism requires a suitable or supportive environment such as temperature, air quality, and sufficient nutrition.
Some people believe that there are other living creatures inhabiting habitable planets out there. However, it is difficult to prove because light takes time to reach our eyes, so if we observe a planet that is very far away hundreds of light-years or more, what we see is not the current condition of the planet but the past.
What Atom Is ?
The smallest unit that composes all objects in the universe and is believed and known by humans today is the atom. For example, to distinguish one material from another, it is important to know the atomic structure of a material.
An atom consists of protons, electrons, and neutrons. If there is a change in the arrangement of protons, electrons, or neutrons, a material can change its properties and become a different material, such as mercury turning into gold. However, if not done properly, it can become radioactive.
Glucose is a very important substance for the survival and development of living organisms. Every organism needs it to survive and grow. Plants with less than optimal photosynthesis tend to develop more slowly because they do not receive a surplus of glucose.
The concept of the atom was first introduced by ancient Greek philosophers around 5 to 4 centuries BC, by several wise men who were students of Leucippus. The concept of the atom was then further developed by an English scientist named Dalton in 1803. Since then, knowledge about atoms has continued to evolve, such as the understanding that atoms consist of protons, electrons, and neutrons.
Atoms will form a compound when they undergo chemical bonding. This occurs when an atom interacts with an opposing atom, attracting each other and creating a compound. However, there is still much to be developed in terms of knowledge about atoms.
The Begining of Universe
The Universe is incredibly vast. Scientists have even stated that humans only know about 5% of the entire universe, while the other 95% remains a mystery. This demonstrates how vast the universe is and how little we know about it.
Furthermore, much of what we know about the universe is based on its past conditions. Light takes time to reach us, and the objects we observe in the far reaches of space are actually in the past. For instance, if an alien or extraterrestrial were to observe Earth from afar, they might see it as it was before the Common Era or even during the time of the dinosaurs if they are far enough away.
Many scientists have their own theories about the origin of the universe. One of the most popular is the Big Bang theory, which explains that the universe was once a single entity and then a certain event caused it to expand into the vast universe we know today.
Some scientists argue that the Big Bang was not the beginning of the universe but rather the end of an old universe and the start of a new one. Regardless, the universe is still full of mysteries, and its evidence is difficult to find factually, which is why there are so many theories instead of laws of physics.
Dark Energy and Dark Matter
One of the components of the universe that most people are unaware of is Dark Energy and Dark Matter. Nearly 70% of the universe is made up of Dark Energy and almost 30% is made up of Dark Matter, which means that the universe composed of atoms is only a very small fraction.
Dark Matter was first discovered by Swiss-American scientist named Fritz Zwicky in 1933, while Dark Energy was only discovered in 1998 by American scientist named Adam Reiss. Before these two important discoveries, the majority of people had no knowledge about the composition of the universe.
Dark Matter, in simple terms, is emptiness because there is no light passing through it, no electronic energy, or more precisely, humans have not been able to explain what happens in that space, making it easier to refer to it as emptiness, although it is actually composed of something unknown.
Meanwhile, Dark Energy is a mysterious force that affects the movement of outer space objects, especially the expansion of the universe that continues to grow. It is called Dark Energy because until now it is still unknown what this object is made of, and it is called Energy because it has the power to move the universe.
Evolution of Universe
We know that the Universe is not static. The galaxy where Earth revolves is moving and wandering through the Universe, and stars explode, creating cosmic objects such as planets, asteroids, and even comets.
The mysterious energy called Dark Energy is what drives the Universe's mysterious movement, causing it to expand or create new cosmic objects due to supernova activity.
Since the mysterious event that occurred in the parent Universe, known as the Big Bang, the Universe has continued to evolve, with stars being born and dying and planets going from habitable to uninhabitable and vice versa.
As we know, the Universe we are familiar with only constitutes 5%, which means that the remaining 95% may have different laws of physics than those on Earth, so there are many possibilities that the Universe is not made up of atoms alone.
Even movements in the Universe that are stronger than gravity, which are essential to the Universe, remain a mystery and are mostly categorized as Dark Energy.
