Science Documentary: Big Bang, Inflation, Multiverse, a Documentary on Cosmology
The Big Bang happened 13.7 billion years ago, but we do not know
what
or why it happened. So far we can only speculate, but we do know that
the Big Bang gave us all the ingredients that make up our universe. All
the energy and matter that exists in our universe was created during
the Big Bang.
Cosmology is the study of the origin of the
universe and the way in which it evolves over time. Since the speed of
light is a constant, this helps us to study the universe. When we look
at stars and galaxies through a telescope, we can determine their age by
measuring the time it takes for their light to reach our eyes. This
measurement of time is light years.
Studying cosmology has
provided us a concise picture of the universe from its origin in the Big
Bang all the way up to today. But there are several questions that we
have yet been able to answer. The first question asked is whether there
was anything before the Big Bang. Did space and time exist prior?
Another question is what is Dark matter. Dark matter is abundant in the
universe. In fact, there is more Dark matter than regular matter in
the universe. Dark matter interacts with gravity but not with light.
When
scientists observe the expansion of the universe, they observe that the
expansion was accelerating. This means that the galaxies were flying
away from each other faster and faster. It is believed that the cause
of this acceleration is due to Dark Energy.
Perhaps the biggest
question is whether there is life somewhere else in the universe. Our
technology to this point has not allowed us to discover life on other
planets, but over the next several decades, scientists believe that this
question may be answered.
Is our universe part of a multiverse?
The standard Big Bang theory suggests that the universe began roughly
13.7 billion years ago from an incredibly hot dense state referred to as
a singularity. But Inflationary theory suggests that the Big Bang was
not the beginning of existence , but it was our own local Big Bang in a
much greater multiverse which already existed.
The standard Big
Bang theory does not describe what banged or why. It merely describes
the aftermath of the bang. This means that the explosion of the Big
Bang had already occurred before the theory begins.
Inflation
is a theory that modifies the Big Bang theory, but is not intended to
replace it. Although the Big Bang theory is a truly successful theory;
inflation is the "bang" portion of the Big Bang theory.
