The Big Bang: "Origin of the Universe"

Have you ever wondered how everything came into being? How was this universe and all that is encompassed in it created? Did everything just appear or was it a result of a higher power? Was evolution prevalent in the universe's creation? Many theories have been created in an attempt to explain the birth of the universe. Some theories are purely based on science, while others are based on beliefs and religion. The theories created by astrophysicists strongly differ from religion based theories.

The first theory used in attempt to describe the creation of the universe is the "steady state theory of cosmology". This theory suggests that the universe "simply exists without changing with time". Since there is little evidence to support this theory, many astrophysicists disregard this explanation. It is evident that the universe expands and even though expansion can be explained in a "steady state universe", this theory is highly disregarded for this reason among many others. Majority of the time, the "steady state theory of cosmology" is included for historical purposes only due to its lack of credibility. The next theory used in attempt to explain the creation of universe is the most commonly accepted, which is known as the Big Bang theory.

The Big Bang theory postulates that our universe was non-existent until about 12 to 14 million years ago. Astrophysicists claim that vacuum fluctuation caused the creation of a singularity. This singularity became our universe. At the very beginning of the universe, there was an incredibly large presence of energy. This form of energy is known as photons. Photons transformed into quarks, which are postulated as the smallest particles in existence. Quarks then formed neutrons and protons. Eventually, Hydrogen, Helium, and Lithium nuclei were formed and this process of formation is known as big bang nucleosynthesis. Cosmic Microwave Background is a prediction about the photons that remained after the big bang. The Big Bang theory's name is derived from the "tremendous explosion" that started the universe. This theory's origin is credited to Edwin Hubble. His observations provided the foundation for the Big Bang theory.

The Big Bang theory led to the inflation theory. The inflation theory is considered a "possible explanation that right after the big bang the universe began a period of exaggerated outward expansion, with particles flying outward faster than the current speed of light". This theory is "advocated" among astrophysicists, but it is not "directly verifiable" and has no clear cut evidence. The theory of inflation is used as an explanation for a phenomenon and is not a theory proven by a phenomenon. Could that mean that the inflation theory is pseudoscience?

There is contradicting information about the origin of our universe when religion is added to the equation. According to religion, the world was created by god or a higher power. In religious theories, God created the universe and everything in it. God created man, earth, animals, stars, and everything else. Is it possible that both groups have valid reasoning? Is it possible that both theories can be intertwined? Is it possible that a higher power created the photons that were allegedly responsible for the birth of our universe? Then perhaps, the real question is how was that higher power created? The origin of the universe can be hypothesized, but will we ever know the truth when science and religion are both factored into everything?

Lindsey,

I liked all of the theoies that you included. I really liked the depth you had. You had tons of information. I also liked all of the different questions you pose.

You wrote an excellent posting, and covered a lot of good information. You write in a very readable manner. Is it possible that matter always existed? That it was always here? Why or why not? Great job!

Jme said...

Of course your post is excellent as always (even if you missed one little question mark, everyone makes mistakes). It was very interesting learning about other theories also. Your last paragraph left us with a lot of thinking to do = )

It could be possible that matter always existed, but it could be possible that a higher power created it. I think that each person could have their own argument depending on their religious beliefs and their scientific convictions. After thinking about the topic a great deal, I really don't know what to believe because I believe in science, but I have my own private beliefs. I really think the origin of the universe is something that we'll never really know for certain, even though there is credible evidence from science. Some people will still put more belief in their religion than in science and that will matter more to them than any scientific evidence.

good job on your blog. i completely agree with everything you say. the big bang theory is very interesting and it seems like you really believe in it. can't wait to hear your next blog.

Always a joy to read! Your information couldn't get anymore accurate! Great way relating it to the first week's post. Your spelling was perfect, and I enjoyed all your punctuations! Don't sweat the small stuff, no one is perfect, expecting it reflects the faults of the expectant.

Fabulously yours,
Megan
