This problem generates controversy about the origin of the universe, if an adult has doubts about it, imagine the doubts that children have with these issues, to dispel this curiosity it is important that you provide valuable and simple information, so that it is easy to understand.
In this universe are located the galaxies, the most incredible planets, and even the smallest particles.
To study the history and components of the Universe, man has used sophisticated observation instruments such as telescopes, radio telescopes, and artificial satellites, which have allowed him to recognize the different celestial bodies that exist in space.
The Universe is very large and it has not been possible to know exactly its size, because it has not been possible to see an edge, of course, if it has one. To understand its amplitude, an airplane can take up to 100 years to cross the Milky Way.
The shape of the Universe
Since ancient times, man has been attracted to know how the Universe is and many have tried to find the answers to this doubt. For the wise Aristotle, the universe was a sphere that contained all the stars, while the philosopher Leibniz in the seventeenth century believed that the universe was infinite.
From the formulation of Einstein's theory of relativity, in the twentieth century, it is believed that the universe is finite, has no limits or center since it corresponds to the curved space.
The origin of the universe
Although the antiquity of the universe cannot be defined with precision, astronomers, from their numerous studies, think that it could have originated 15 billion years ago.
According to the Belgian astronomer Georges E. Lemaitre, he considered that at the beginning the universe was a concentration of matter and compressed energy which he called "cosmic egg", which then exploded and its fragments dispersed in all directions of space. Then, in some phase, the contraction of the gas occurred, giving rise to the first galaxies. This theory is known as the Big Bang Theory or the Great Explosion, which occurred 14 billion years ago.
This theory explains the origin of the universe because the data was recorded by the artificial satellite COBE (Cosmic Fund Explorer) that corroborated the success of this hypothesis.
It seems wonderful and exciting to know the theories that originated the formation of the Universe, playing an important role, the work that God did with the creation that was supernatural. In addition to the science that put its grain of sand with the provision of the telescope, which facilitated the investigation and from there, appeared numerous scientists who made known their theories and that today is the information we have.
Surely many children are interested in the Astronomy lessons and it does not just happen to adults. In addition, with this type of teaching in the classroom, it is possible to stimulate critical thinking and encourage interest in science, since to start in this vast world only curiosity is required and this characteristic is typical of children.

This is the type of knowledge that must be taught in all schools worldwide. There's a belief that this is only for few people who have fond of science. I think this evolves everyone. It's the creation of the universe! And we, as a small particle, are part of it.
