Essay On Big Bang Theory

The Success of the Big Bang Theory

At the beginning of time, there was nothing. In a sudden “bang”, the entire Universe and all of the energy in it began to expand outwards from one point. According to many scientists, this is how the Universe began. This theory is known as the Big Bang theory, and it is one of the most widely accepted explanations for the origin on the universe, both among scientists and ordinary people. Part of the theory's success is the strong evidence supporting it; however, even though it is widely accepted, it still has flaws.

What is the Big Bang theory?

Before exploring the strengths and weaknesses of the theory, it is best to explain what it is. The Big Bang theory states that the Universe suddenly existed as an

infinitely dense and hot point that contained all of the energy in the Universe. That point began to expand, releasing all of the energy and matter into the newly created space. To this day, the Universe is still expanding.

Why is the theory widely accepted?
The theory is widely accepted for several reasons. There is a lot of evidence supporting the Big Bang theory, including redshift and cosmic microwave background radiation. (Singh) This evidence points towards the Big Bang being an actual event. The theory has also been developed over decades of research. The theory was proposed in 1927 by Georges Lemaitre, and has increased in popularity since then. ("Georges Lemaitre, Father of the Big Bang.") The theory does not directly contradict most major religions. Pope Francis has endorsed the theory, stating that "the Big Bang . . . does not contradict the intervention of the divine creator but, rather, requires it." (Withnall) Lemaitre, who initially proposed the theory, was a Catholic priest. ("Georges Lemaitre, Father of the Big Bang.")

What evidence supports the theory?
There is a lot of scientific evidence that supports the Big Bang theory. For example, no items in the universe have been proven to be older than the age of the Universe proposed by the theory. (Singh) Redshift, the effect that causes wavelengths to lengthen when emitted by an object moving away from you, has been observed in light from many distant galaxies. (“Red Shift”) This redshift shows that these galaxies are all moving away from something. The continual expansion of the Universe described in the Big Bang theory explains why all of these galaxies are constantly moving away from the center of the Universe. (Singh)

Another piece of evidence for the Big Bang theory is the CMB, which stands for Cosmic Microwave Background.

What are the weaknesses of the theory?

Although the theory is strongly supported by scientific evidence, it is not without its flaws. The theory cannot explain what happened before the Big Bang, or what the universe is expanding into. Some scientists say that certain galaxies are too large to have formed in the theory’s age of the Universe. The theory appears defy the first law of thermodynamics by claiming that energy was created by the Big Bang. The theory also violates the second law of thermodynamics by claiming that orderly structures of galaxies, planets, stars, and even life could form out of the complete chaos of the Universe’s earliest stage.

Conclusion

Is the Big Bang theory true? Despite all the evidence supporting the theory and its acceptance by scientists and ordinary citizens worldwide, we cannot say for sure. We can, however, claim that it is a reliable way to explain the origin of the Universe using our current knowledge. The success of the Big Bang theory revolves mostly around the evidence supporting it. The next successful theory, if there is one, will likely address the flaws of the Big Bang theory. As we discover more and more about the origin of our universe, there is one important question to keep in mind: Will we ever know the truth about how we came to

be?
