    The Big Bang Theory is one of the most popular explanations as to how the universe began. Most scientists believe that the entire universe was generated by a single explosion, giving this theory its namesake. For years, scientists have been working on accumulating evidence that supports the Big Bang Theory. Over time, physicists were able to strongly support the theory. Today, the Big Bang Theory is credited for the birth of the universe. In short, this theory explains that all matter was once contained in a microscopic ball. As time progressed, this small ball expanded, eventually forming the universe. Evidence suggesting this widespread theory includes cosmic background radiation, Hubble’s Telescope, and the continuous expansion of space.

Cosmic Background Radiation

    Allegedly, the universe was developed from virtually nothing. Scientists have thoroughly researched the Big Bang Theory and discovered that there are many ways this theory can be proven. The evidence collected on the Big Bang Theory confirms the premonitions of many scientists and reinforces the idea of a never-ending universe. Evidence such as background radiation suggests that the Big Bang Theory is responsible for fabricating the entire universe, as we see it today. Background radiation is the amount of radiation left over within an environment. Our atmosphere on Earth has tremendous amounts of excess radiation. Households all over the world need to maintain certain levels of radiation in order to function and operate. Necessary for both heat and electricity, radiation plays an important role in a household. Some elements of radiation such as uranium are even found in glassware. This radiation is vital for an environment and allows the surroundings to have controlled levels. The same idea applies to life on Earth. After the explosion created by the Big Bang Theory, scientists have discovered that there are amounts of radiation found within our planet. This is called cosmic background radiation. 


    Scientists firmly believe that background radiation within the Earth is a result of the Big Bang Theory. This idea is highly likely because the Big Bang Theory created an intense explosion that must have produced enormous quantities of radiation. Cosmic background radiation allows light to escape from the Earth. Scientists can predict that without cosmic background radiation, light would not be able to pass through the Earth. Partly due to cosmic background radiation, life can thrive on Earth. These radiation levels, in fact, benefit humankind. It allows us to further expand our knowledge about the natural world. Radiation highly connects to the Big Bang Theory and strongly supports it. We are aware that radiation exists within the planet. Therefore, the most comprehensible explanation of this is the Big Bang Theory.

Hubble Space Telescope

    Another valid form of evidence that supports the Big Bang Theory is Hubble’s space telescope. With this advancement, astronomers are able to understand the universe from about 500 million years after the Big Bang. The Hubble space telescope proved that the first stars along with galaxies were formed much earlier than scientists had believed. Edwin Hubble was responsible for understanding the Big Bang Theory’s effect on the universe. His telescope proved that the universe would continue to expand. In addition to these ideas, Hubble was able to identify the distance between galaxies. He learned that the velocity of a galaxy directly relates to a galaxy’s distance. This would imply that a galaxy that is three times as far from the Earth would move three times faster as well. Evidently, the universe’s birth began from a singular, central point that steadily increased with time. This resulted in the immense expansion of the universe. 

  

    Hubble’s space telescope largely impacted the scientific community. This idea mostly supported the Big Bang Theory. As astrologists know, after explosions and immense pressure in space, matter moves away. The Big Bang Theory is said to have produced a large explosion, hence the “big bang.” Hubble was able to prove that the universe is expanding from one point. This point lies toward the center of the universe and all of the matter created has been increasing outward. Another concept applies to the Big Bang Theory. This is the red shift of light. The red shift is a light source that depicts the idea that stars and galaxies are still expanding rapidly. Hubble’s space telescope provided a variety of evidence that supports the universe’s birth through the Big Bang Theory.


    The Big Bang Theory answers several questions about the birth of the universe. According to New York Times writer Walter Sullivan, “Its substance and energy formed spontaneously during an initial period of expansion when, in the tiniest imaginable fraction of a second, the universe repeatedly doubled its size.” The Big Bang Theory is credited with both the history and structure of the entire universe. It is difficult to imagine that our infinite and continuous universe “...emerged from nothing or from almost nothing (The New York Times).” All the same, the possibilities are endless and science will never stop progressing.
