Have you ever wonder how universe was formed? Or even dreamed to explore outside the earth?

Well, that was so fantastic and fabulous to think. Many queries tickles every cerebrum of individuals here on earth that invented unusual kinds of devices, spaceships and even stupefying suites to reach and witness the amazing contemplate outside the world we live. There comes the astronomers that spend almost half of their lives in experimenting and discovering the mysteries behind the peculiar creations and picture it all out to publish in the world and to parcel out the elegance of the whole universe that fill in the brains of humans about the outer space.

Due to this passion and intimate desire of minds that eager to reveal the furtive behind the creations, there goes the various theories that until now, it is not yet done searching for documents and truths. The first one is the Big bang theory which states that between 13 billion to 15 billion years ago, all the matter and energy in the known cosmos was crammed into a tiny compact point. The big bang theory seeks to explain what happened at or soon after the beginning of the universe. For the time before that moment, the classical theory of gravity is no longer adequate.

According to the big bang theory, the universe expanded rapidly in its first microseconds. A single force existed at the beginning of the universe, and as the universe expanded and cooled, this force separated into those we know today: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. A theory called the electroweak theory now provides a unified explanation of electromagnetism and the weak nuclear force theory. Physicists are now searching for a grand unification theory to also incorporate the strong nuclear force. String theory seeks to incorporate the force of gravity with the other three forces, providing a theory of everything (TOE).

Once the expansion of the initial inflationary...
