How the Universe Was Created

Hello Guys,

Below, I will be describing to you how the Universe was created.


Although nobody can be sure how the Universe began, most scientist believe that it was born from an enormous explosion 13 billion years ago. This explosion, called the “Big Bang”, was the point where space and time come into existence and all the matter in the cosmos started to expand. Before the Big Bang, everything in the Universe was compressed into a minuscule are a no bigger area than the nucleus of an atom.

 


The Big Bang was an unimaginably violet explosion that sent particles flying in every direction. A process called cosmic inflation caused the Universe to expand into an area bigger than the entire Milky Way in less than one second. Moments later, the temperature began to decrease, and the Universe began to settle down. Stars and galaxies began to form roughly one billion years after the Big Bang.

The Book of Invention: The Jet Aircraft

Image
  In 1939, World War Two began in Europe. This war would last for almost five years. In Germany, Hans von Ohain designed and installed a completely new type of engine in an aircraft, an engine which would enable the aircraft to fly at a truly high speed. This was the first jet engine, pushed forward by air which was first sucked up and compressed, and the exhaust gases expelled at great pressure. Two years later, quite independently of von Ohain, an English engineer, Frank Whittle achieved the same results. But the first people to install the new motor in an aircraft were the Germans. Their Messerschmitt Me 262 , used during the last stages of the Second World War, gave the best performance.                 By the end of the War, jet engines had begun to be used in passenger aircraft, too. Now, people could fly at higher speeds and so complete their journeys within an unbelievably short time. Passengers tr...

How The Solar System Was Formed

Image
  Hello Guys , I will be telling how the Solar System was formed. Our Solar System formed from the force of an exploding star. When some stars reach the end of their lives, they can explode into a supernova, sending shockwaves of energy deep into space. Roughly 4.6 billion years ago, a shockwave from a supernova, travelling at 30 billion kilometers (19 million miles) per hour, hit a cloud of ice, dust and gas. The force of the impact caused the cloud to flatten and rotate. From the spinning disc, our Solar System began to form
