What is the universe made out of for kids?
The Universe is all of time and space and its contents. It is made of many millions of millions of stars and planets and enormous clouds of gas separated by a big space. Astronomers can use telescopes to look at very distant galaxies.
How big the universe is for kids?
No one knows for sure just how big the universe is. It could be infinitely large. Scientists, however, measure the size of the universe by what they can see. They call this the “observable universe.” The observable universe is around 93 billion light years across.
What universe is made of?
The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
How big is the Universe?
about 93 billion light-years
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Are there Multiverses?
Among physicists, it’s not controversial. Our universe is but one in an unimaginably massive ocean of universes called the multiverse. If that concept isn’t enough to get your head around, physics describes different kinds of multiverse. The easiest one to comprehend is called the cosmological multiverse.
What is universe in simple words?

What is inside the universe?
The universe ( Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter.
How do you think the universe began?

How big is the universe?
The observable universe is about 46 billion light years in radius. Scientific observation of the Universe has led to inferences of its earlier stages. These observations suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history.
