What is Universe, How it is formed
The Universe is a large space that contains everything i.e. all matters and energy, from the smallest particles to the largest particles, whatever in the space is universe. It contains all the planets, stars, asteroids, meteors and all the galaxies. No one knows the size of the Universe. The astronomers believe that the universe is still growing outwards in every direction. Astronomers continue to investigate about it. One way they do this is by “using a spectroscope”. A spectroscope measures the color of light coming from an object. Changes in the color indicate whether an object is moving away from or towards the Earth. After the readings of spectroscope scientists believe that the universe is still growing outwards in every direction.
How Universe formed
According to the astronomers first everything was an incredibly solid, heavy ball of a matter. This heavy ball exploded billion of years ago and as a result the Universe was formed. The moment of the explosion of this ball is known as “Big-Bang”. After this explosion the early universe was very small and too hot but later it got cooled and it exploded and spread out into the small pieces. Small pieces formed the basic elements called hydrogen and helium. Then the pieces join together which results object formed. Over billion of years the object becomes Galaxies, Stars and Planets. How the universe was formed is still only an idea.
