The Origin of the Universe
There are many different theories on how the universe started but the most known is that of the Big Bang theory, or in other words, the great explosion. This explosion occurred about 10 or 20 billion of years ago when absolutely nothing existed, and caused a gigantic cloud of dust and gas and was extremely hot. This cloud was even in shape but began to grow and grow at such a tremendous speed suffering temperature changes along the way. It was at this stage that the universe began to form.
These changes made some parts of the gigantic cloud grow a lot slower than others, therefore creating condensation, forming Astros such as stars and planets which in turn created their own galaxies, or even this very solar system, which for us is the most important system which exists in the sky, because it is where our planet, planet Earth is.
