How Big is the Universe? You Need to Know This First.

How big is the universe? This question often intrigues some people just because they are curious. Below are some things you need to know before answering or even asking this question again.

If the Earth where we stand is so vast, then what about the universe? Of course, it is much wider, and it feels like it will not reach the mind.

About the Universe, You Need to Know

How big is the universe? It is still difficult to answer even by experts. However, these few things might provide a little clue about how vast the universe in which we live is.

1. The Universe is Unlimited Space

The universe is often also called the universe, which is a place where energy, matter, and even living creatures exist. The universe turns out to be an infinite space and is still expanding wider to this day.

According to experts, the universe was formed around 13.75 billion years ago. In the universe, there are trillions of stars. A collection of stars in a cluster is called a galaxy. Meanwhile, collections of galaxies are called superclusters.

2. The Virgo Supercluster is a Collection of Galaxies

The Local Group or Virgo Supercluster is a collection of galaxies observed by experts on Earth. The Virgo Supercluster is one of the millions of superclusters in the universe.

The Virgo Supercluster has at least 100 galaxy groups and clusters within it. This includes the Milky Way and Andromeda galaxies in the Virgo Supercluster.

3. A galaxy is a collection of billions of stars

Galaxies are collections of stars whose numbers can reach billions. The Milky Way, or Milky Way galaxy, is one of the many galaxies in the universe. The Andromeda Galaxy is the closest galaxy to the Milky Way.

According to experts, there are around 200 billion stars in the Milky Way galaxy. One of these stars is, of course, the Sun. The star we call the Sun is the center of the solar system where the Earth is in the system.

4. Stars are giant balls of nuclear furnace gas

Stars are very large, spherical gases that are very hot and emit light. The closest star to Earth is the Sun, which is 149,680,000 kilometers away. In the core of the Sun and other stars, hydrogen is converted into helium, accompanied by the release of enormous energy.

That's why the Sun and stars are like a giant nuclear furnace. There are trillions of stars in the universe. There are only about 2,000 stars that humans can see from Earth without the help of instruments.

Ultimately, this article does not answer the question of how wide the universe is. However, the four things explained above about the universe can at least give an idea of how vast the universe is.
