What are you waiting for? The origin of Earth and the universe
Hello friends and welcome to another new Happy Learning video. Today we are going to learn about how it all began, today we are going to learn about 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 billions years ago when absolutely nothing existed, not the galaxy, nor stars, and not even Earth. This explosion caused a gigantic cloud of dust and gas and the temperature was incredible high, it was really super 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, plant Earth is.
The sun is located in the center of the solar system and it is this star that has made it possible for life to exist on earth but when did the earth begin? Was is always as it is today?
Experts say that the earth was formed 4.650 million years ago. Apparently there was a ring of matter circling the sun. Some of this matter began to join together forming what is known today as planet earth.
Whilst this was happening, the earth's surface was being bombarded by meteorites and comets. The comets brought water in the form of ice, which was then frozen and solidified, making the earth's surface solid, and when it evaporated, heavy clouds were formed.
When the earth's temperature descended, the clouds produced an almighty downpour, as in the largest flood one can imagine.
As from then, the water began to cool giving birth to life, this beautiful life.
So now you know, we must take care of our old Earth, and not dirty it with waste and contamination. We must respect all that is around us and learn to love nature and all living creatures inhabiting it.
So goodbye friends, and don't forget to subscribe to the Happy Learning universe.
