Our universe is incomprehensibly huge, holding billions of galaxies, trillions of stars and an innumerable amount of planets, moons, asteroids, comets and more.
Everything is spinning through the expanse of space.
It’s impossible for us to know much about the creation of the Universe since none of us were there. Even more so, we don’t have a great understanding of what exists in space today.
Astronomers and physicists have discovered that everything we can see in the Universe– planets, stars, galaxies– only makes up 4% of it!
The majority of the Universe is actually empty space.
So, it could be said that what truly defines our Universe is not necessarily the visible objects within it but rather the emptiness around them.
What is the Universe made of?
We have come to understand that it is primarily composed of two things: dark matter and dark energy.
Dark matter, although still relatively mysterious, is believed to make up about 27% of the Universe’s composition. It cannot be seen directly but its presence can be inferred through its gravitational effects on visible matter.
Dark energy, making up about 68% of the Universe, is even more elusive and not well understood. It is thought to be responsible for the acceleration of the expansion of the Universe.
The remaining 1% of the Universe is composed of visible matter, including stars, planets, and all forms of life.
While our understanding of the composition of the Universe is constantly evolving, it’s clear that there is much more left to be discovered.

What is the universe made of elements?
The visible matter in the universe is made up of atoms, which are composed of protons, neutrons, and electrons. These elements were created in the cores of stars through nuclear fusion.
The process of nuclear fusion involves the fusion of two atomic nuclei to form a single, larger nucleus. This release of energy is what powers stars and allows them to shine.
However, dark matter and dark energy do not appear to consist of atomic particles and their exact nature is still unknown. Scientists believe that dark matter may be made up of exotic particles that have yet to be discovered.
As for dark energy, it is theorized to be a type of vacuum energy that is constantly pushing the universe apart.
Although we cannot see or directly detect these mysterious components, their effects are observable and scientists continue to study them in an effort to better understand the makeup of our universe.
Is the universe made of energy?
The universe is primarily composed of energy.
The famous equation E=mc2 tells us that matter can be converted into energy and vice versa. This means that even the atoms making up visible matter contain immense amounts of stored energy.
In addition to the energy contained within matter, the universe also contains vast amounts of dark energy, which is thought to make up around 68% of the total mass-energy budget of the universe.
The nature of dark energy is still largely a mystery, but scientists believe that it is responsible for the accelerated expansion of the universe.
While the exact composition of the universe is still unknown, it is clear that energy makes up a large part of it.
And as our understanding of physics continues to evolve, we may find that the universe is even more mysterious and fascinating than we ever thought possible.

Final words
The universe is an unimaginably vast and complex place. And while we may never fully understand all of its mysteries, scientists have made great progress in uncovering its secrets.
Today, we know that the universe began with a Big Bang over 13 billion years ago. Since then, it has been expanding and evolving into the incredible place that we see today.
Along the way, it has given rise to an astonishing variety of stars, planets, and other objects. Each of these plays a unique role in the grand cosmic story.
And while there is still much to learn, the study of the universe continues to be one of the most rewarding and fascinating pursuits imaginable.
