Essay On Big Bang Theory

Improved Essays
The Big Bang Theory is the on-going explanation about how the universe began. The theory talks about the universe as we know it starting with a small originality, then expanding over the next 13.8 billion years to the universe we know of today. The phrase "Big Bang Theory" has been popular among astrophysicists for decades. The idea is that the universe began with an explosion more than 14 billion years ago, and many scientists also believe our universe and others, come from a “singularity”. According to the theory formulated in 1927, the universe is still expanding today. The known evidence for the Big Bang theory suggests that there is an existence of a Cosmic Background Microwave Radiation, and Red Shift.

Many theories predicted that after “The Big Bang”, there would have been a remarkable amount of release of radiation. Billions of years later, this radiation would also have been continuing to move away faster from us that the wavelength from this radiation would have been moved from being visible light to the CMB we see today. One of the major pieces of evidence for the big bang theory is that galaxies appear to be moving away from us at speeds that are relational to their distance. This piece of evidence is known as “Hubble’s Law”, and this phenomenon was discovered in in1929 by Edwin Hubble. His observation supports the expansion of the universe and also proposes that the entire universe billions of years ago, was once compacted. This piece of evidence discovered by Edwin Hubble, has provided many modern day astronomers with much needed help to gain evidence for the theory of the Big Bang. It has also been discovered that the abundance of “light elements” Hydrogen and Helium which have been found in the universe, have also helped to support the Big Bang Theory beginnings.
There is a lot of controversy about the Big Bang Theory and the evidence provided for it. The Big Bang is currently an accepted theory for how the universe came to be. Evidence for it seen and heard of everywhere

    This past Thursday we were placed into groups and asked to read Alan Lightman’s essay What Came Before the Big Bang. The Big Bang happened some fourteen billion years ago as a state of infinitesimally dense and small, superheated ball of matter, which has been expanding ever since. And as far as we know, the universe will keep expanding forever. What scientists are trying to figure out is if there was anything before the Big Bang, essentially, they are trying to figure out if time had existed before the creation of the Big Bang.…

    Astronomy is an ongoing process. It is always changing and improving as we discover new stellar objects and use more advanced technology. For example, people once believed that the Earth was flat, and the sun and other planets orbited around us. As we advanced in technology, we proved both of these ideas to be false. Even today there is still work to be done, ideas and theories to confirm and disprove, and plenty of other things to explore.…

    The big bang is the rapid expansion of matter from a state of extremely high density and temperature that according to current cosmological theories marked the origin of the universe. 3. This is the red shift the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance. Stars 1.…

    “There is sufficient reason to believe that God is the cause of the universe” The cosmological argument is a multitude of arguments that have been developed to modern day ideas. These arguments are based on natural theology; this is when someone has knowledge of God based on experiences. It is a philosophical argument that aims to prove the existence of God. The cosmological argument rejects the idea of infant regress because if that is the cause there is no need for God.…

    At a young age majority of us grew up believing that there is a higher being above us that created us, that shaped our lives to be where it is now, and that being is known as god. When we were a child, we did not have a choice whether we truly believed in the existence of God. We were told what to believe and never questioned it that belief. In this essay, I will analyze the existence of god between “Does God Exist?” by Ernest Nagel and “Why God Allows Evil” by Richard Swinburne. Although Nagel rejects the existence of God, he establishes two causes for why God exists.…

    The existence of God has been a topic that has been widely debated and discussed by various philosophers throughout past centuries. Even though it is nearly impossible to prove beyond a shadow of doubt that God definitely exists, His presence is still felt through the evidence of his work. The fact that God is not something made up of matter and not someone we are able to see with our own eyes makes it easy for people to be skeptical of his existence. But to simply dismiss His existence because he is not apart of the physical world would be to ignore the different arguments and justifications made throughout history about Him. Philosophers throughout history have approached the question of God’s existence with several different arguments.…
