What are some interesting facts about the solar system and the universe and supernovas? And how does the system works? Universe was formed 13,7 billion years ago after the Big Bang. It was formed by hot, dense and pure energy particles of a small dot that our minds cannot even imagine.
The forces appeared after the Bing Bang formed the gravity. As the famous E=mc2 formula of Einstein states the pure energy turned into matter particles and at the same time, antimatter appeared. They fought mercilessly with matter to annihilate each other. Only one of the billions of particles found in matter built the universe by winning this fight.
Yet the snowy screens of our TV’s still perceive the energy of the antimatter that was transformed to radiation. Hydrogen, Helium and Lithium elements that were appeared in the first minutes of the formation of the universe formed stars 200 million years later, first galaxies 1 billion year later, and the sun and the earth 9 billion years later.
Who knows what was thinking the primitive man after seeing the day turning into night all of a sudden and the dark sun shining with a strange light? But the solar eclipse is an explainable natural event for today’s man. Moon is four hundred times smaller than the sun and as it is 400 times closer to earth than the sun, we see it as if it had the same size with the sun. During the orbital movements of the earth and the moon, sun, moon and earth come in same alignment.
The Moon stands between the sun and earth. And when it covers the sun partially or fully, we observe a solar eclipse. Solar eclipse is appeared at least 2 and at most 5 times a year. In the total solar eclipse the moon covers the sun fully. And in places where the moons shadow falls on the ground people experience twilight in the middle of the day or even see the stars. Only a total solar eclipse can be watched with naked eyes.
Stars born in the cloud piles formed by dust and hydrogen gas. These clouds get hot by the compression of the gravity force and form stars throughout millions of years. As the mass of the stars get bigger their lifespan shortens. Stars heavier and bigger than the sun consume their energy much more rapidly and die with violent explosions.
These giant stars fight continuously with the gravity force. As their over-heated active particles form a pressure towards exterior, the gravity force tries to compress them in the core. And when the gravity force wins the fight, the star collapses in lesser than seconds.
With the repulsion of the collapsed star’s core violent and big explosions called supernova appear. Supernovas spread to the universe new stars, planets, satellites and elements that created us. While giant stars die and torn into pieces, they give us life.
