Chapter 5: The Origin and Fate of the Universe
This chapter discards the idea of Black
Holes and goes back to what I thought was interesting, The Universe. This
chapter begins by explaining the Big Bang Theory. For more information, look at
my page labeled "Big Bang Theory for Dummies". The chapter then
transitions into alternative ideas of the universe such as the Inflationary
model. The inflationary model is similar to the big bang theory. The theory
suggests that the early universe had a very rapid or exponential expansion.
This expansion accelerated as time went on until gravity began to slow it down.
The chapter then talks about laws which we require in order to find out more
information about our universe. These laws must require quantum physics
however are currently unknown.
In order to succeed in understanding this chapter I needed to
research three main parts. I needed to understand; the difference between the
Big Bang theory and the Inflationary model, Cosmology and Quantum physics.
I started off by going onto http://www.felderbooks.com/papers/inflation.html
, I began by reading the introduction. The introduction helped me learn that
the big bang theory and the inflation theory go side by side. When the big bang
theory was originally created, Einstein learned that the universe was not static;
it must be either expanding or contracting. There were however many problems
with the big bang theory. These problems were not able to be solved. This is
when a modified theory which is formulated from the big bang theory comes into
play. It is very similar but is different in the first few seconds of the Big
Bang. This is a phenomenal site; I wish I had found it earlier. It uses a very
appropriate language and explains with detail.
The second research topic which I wanted to tackle had been
Cosmology. I started my research with a paper I found online. It is called “Introduction
to Cosmology” by Barbara Ryden, Department of Astronomy, and The Ohio State
University. It was a very long paper so I decided to read the introduction. Cosmology is the study of the universe or
cosmos, regarded as a whole. It is a science which regards entire galaxies as
small objects. It is an attempt to answer questions such as “where do we come
from”, “what are we” “where are we going” etc… Cosmology deals with distances
that are very large, objects that are very big and timescales that are very
long.
I then regoogled Cosmology in order to get a non textbook answer
of what it is. I found that it is “the branch of astronomy involving the origin
and evolution of the universe, from the Big Bang to today and on into the
future. http://www.space.com/16042-cosmology.html
I started off researching Quantum physics by searching it up on
space.com. I was not able to find anything. So I gave up from that site. I then
decided to google “Quantum physics for Dummies” I thought this would be an
ideal was to find what Quantum physics is in simple terms. I found many
websites but the only one who gave me a real answer of what quantum physics is
the most unreliable source, Wikipedia. I thought the definition did give me a
starting base however. “Quantum mechanics is the science of the very small; the
body of a scientific principles that explains the behavior of matter and its
interactions with energy on the scale of atoms and subatomic particles.” I left
this site right after because I did not want to waste anytime with an
unreliable source.
