Universe.. Where Did You Came From?

The topic for my today's blog is all about the origin of the universe. As what I know there are 6 theories of how the universe came to existence. My 1st theory that I want to explain is the Steady State Theory. The Steady State theory (also known as the Infinite Universe theory or continuous creation) is a model developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others. In steady state views, new matter is continuously created as the universe expands. The theory requires that new matter must be continuously created (mostly as hydrogen) to keep the average density of matter equal over time. The amount required is low and not directly detectable: roughly one solar mass of baryons  per cubic megaparsec  per year or roughly one hydrogen atom per cubic meter per billion years, with roughly five times as much dark matter. Such a creation rate, however, would cause observable effects on cosmological scales.The 2nd theory  is the Big Crunch Theory. The Big Crunch Theory is made possible by Big Bang cosmology, which states that all matter in the universe is now racing away from all other matter. If there is enough matter in the universe to create a gravitational force sufficient to bring this movement to a halt and to reverse its direction, then at some point in the remote future all matter in the universe will converge into an infinitely dense point in space, resembling a massive black hole. The end of the universe would then resemble its beginning—a singularity at which the laws of physics as we know them no longer apply. Such a universe is called a closed universe. The 3rd theory is the Chaotic Inflation Universe. Chaotic Inflation, proposed by physicist Andrei Linde, models our universe as one of many that grew as part of a multiverse owing to a vacuum that had not decayed to its ground state. In this theory, the peaks in the evolution of a scalar field (determining the energy of the vacuum) correspond to regions of rapid inflation which dominate, creating "bubble universes", making the structure of space fractal on the very largest scales, likely at scales larger than the observable universe. The 4th theory is Big Bounce Theory. The Big Bounce Theory combines the big bang and big crunch theories to create a vision of an endless, cyclical cosmos in which the universe repeatedly expands from a singularity only to eventually collapse back in on itself -- before doing it all over again. In other words, a big bounce universe would continuously expand and contract. the 5th is the Cyclic Universe Theory. The cyclic theory of the universe is a radical alternative to the standard big bang/inflationary scenario that offers a new approach for resolving the homogeneity, isotropy and flatness problems and generating a nearly scale-invariant spectrum of fluctuations. The 6th Theory is The Big Bang Theory. The Big Bang Theory is the prevailing cosmological model of the early development of the universe. The major premise of the Big Bang theory is that the universe was once in an extremely hot and dense state that expanded rapidly (a "Big Bang"). This rapid expansion caused the young universe to cool and resulted in its present continuously expanding state. According to recent measurements, scientific evidence and observations, the original state happened around 13.7 billion years ago which can be referred to as the time that the Big Bang occurred. As for now this is what I can say. God Bless!
