COSMIFICATION

A lot of scientists think that the Universe began nearly 13.7 billion years ago with a massive explosion of an extremely hot bubble that was thousands of times smaller than a pinhead. This idea at first was jokingly referred to as the ‘The Big Bang’. But as the time progressed evidence piled up the concept and the name stuck with the scientific community after the explosion the Universe that we know today was born with its Time, Space and Matter came into existence.

It is an amazing fact that all these happened in a fraction of a second. In just a Matter of a second the Universe grew from smaller than a atom to bigger than a galaxy and it kept on expanding at a phenomenal rate and continues to grow even today.

As the Universe cooled down, the energy converted into particles of Matter and Antimatter. These two opposite types of particles fought hard and largely destroyed each other. But some brave Matter managed to survive. Just one second has gone by so far since the beginning of everything and the Universe had already grown into one hundred billion kms and is cold enough to form more stable particles called Protons and Neutrons. Over the next three minutes the temperature fell below 1 billion degrees Celsius. Now the Universe got colder to allow the Protons and Neutrons to come together and form its first Atom. After millions of years when the Hydrogen gas clumped together and gravity started to put it under pressure stars and galaxies began to form. Their radiation began dissolving the stable Hydrogen gas into plasma that allowed visible light to pass and finally, there was light.

The single super-concentrated point or bubble which later became the Universe before the Big Bang was called the “Primeval Atom” or the “Cosmic Egg” also in one of the possible scenarios for the ultimate fate of the Universe known as The Big Crunch the Universe will eventually stop expanding and start collapsing in one itself. Then, however, another Big Bang might happen.
