Abstract. We intend to investigate the question of whether or not a correlation exists between
Cosmic Background Radiation (CBR) and the density and energy of the Universe. In order to
explore this idea, we propose the following hypothesis: If we look at areas with similar CBR,
similar amounts of matter and energy will be present. Our process will include finding areas with
similar CBR and comparing them.
Cosmology, the overarching study of the Universe, provides an infinitely wide range of
potential queries. When these various topics are investigated, the resulting information leads us
to greater knowledge of the Universe. Our research team decided that studying this area would
be both beneficial and intriguing. We determined that our goal would be to study whether or not
there is a correlation between the distribution of Cosmic Background Radiation (CBR) and the
amounts of matter and energy in the regions of interest.
In order to fully understand our topic, we first needed to research several topics, the first
of which was CBR. We learned that CBR is a form of electromagnetic radiation, created soon
after the Big Bang, which fills the entire Universe. Most importantly, it provides us with
information about the structure and composition of the early Universe. In addition, we
researched critical density, which acts as a sort of boundary. If the density of the Universe is
larger than the critical density, the Universe will collapse, and if the density of the Universe is
smaller than the critical density, the Universe will expand. If the density of the Universe were to
equal the critical density, the Universe would stop expanding but only after an infinite amount of
time. This would become an important aspect of our project in forming a connection between
CBR and density.
