"In early 1998, two groups of astrophysicists made a startling announcement. The universe, which had always been thought to be expanding, and gradually slowing down, might actually be speeding up" (Fox 1). It turned out that there was a mysterious energy that was resisting gravity and enlarging the universe at vast speeds. Now that this new information had arisen, scientists had to adjust their current knowledge, modifying the big bang theory. .
In the beginning, there was "a nothingness in which packets of energy fleeted in and out of existence, popping into oblivion as quickly as they appeared. One of these fluctuations had just enough energy to take off" (Fox 9). That searing hot ball of energy expanded in space and time in one big bang and ultimately cooled down, creating matter.
The first astronomer to discover that the universe is expanding was none other than Edwin Hubble. In 1929, Hubble began to study redshifts, quasars that appear redder as it moves farther away. The relationship between distance and redshift is now known as Hubble's Law. Hubble's discovery concluded that the universe is expanding. The further the galaxy was, the faster it moved. Now that it was official, there needed to be a reason why the universe was expanding. .
Even before Hubble's discovery, Einstein's general relativity theory gives a reasonable answer to why the universe is expanding. "According to the theory, objects moving in a gravitational field follow curved trajectories simply because space and time are themselves curved" (Parsons 24). Another piece of supporting evidence of the big bang theory is that the giant explosion fifteen billion years ago created billions and billions of lightweight particles that would unite to form heavier ones. These smaller particles: protons, electrons, and neutrons, would make up each atom, which is the basis of all matter. Thus, the explosion provided everything needed to produce a universe.
My report is about the Big Bang Theory. ... First, I will start with how the Big Bang Theory came about. ... That is one way that astronomers believe that the big bang theory is true. ... The Big Bang Theory is the dominant scientific theory about the origin of the universe. ... The Big Bang Theory is therefore considered the beginning of time. ...

The Big Bang, written by Peter N. ... The article discusses why the Big Bang cosmological theory is almost universally accepted as the most reasonable theory for the origin and evolution of the universe. ... It is all but forgotten that the Big Bang is not a fact, but an unproven theory. ... This article is not highly useful when it comes to the explanation and the evidence for the Big Bang theory and alternative resources containing explanation of the theory, its views and issues should be consulted as the article barely touches on the evidence in support of the Big Bang theory. ... Furthe...
This theory, to how the universe was created, is known as the Big Bang. ... I believe, even though my religion contradicts my opinion, that this theory for the universe in completely believable because of the fact that so much evidence and theory, that makes sense, backs it up. Undeniably, there are those who believe that this theory is unbelievable because of the fact that an atom, smaller than one that creates the desk they work on, exploded and made our universe. ... This is believed to disprove the theory, along with the fact that our galaxy and universe seems to contract and expand to ...
The biggest idea in science that I was assigned to was the Big Bang theory. ... This spot they call it the "primeval fireball" which must have been very hot and extremely dense, and it eventually exploded which was the big bang. ... The continued expansion theory where the universe will keep expanding forever and the oscillating universe theory wills the gravitational force will bring all the matter in the universe back into another primeval fireball and another big bang will occur. ... If the mass is too little then the universe will keep expanding and if the mass is enough then another pr...
Science affirms that the Universe was created 15 billion years ago during a huge explosion called the Big Bang; religion claims that the Universe was created by an omnipotent Being that lives and acts with supernatural powers. ... Following this argument, we can almost conclude that Raymo is capable of "experiencing" the Big Bang! For Raymo, religion begins with science, therefore God either came into existence when the Big Bang took place, or the Thou caused the Big Bang and acted upon the laws of physics ever since then. ... And this assertion is what leads us to Gould's approach in sol...
Theories of the Earth When the beginning of the Earth comes to mind you probably think of at least one theory called the Big Bang Theory or perhaps Darwin's Evolution Theory. ... The four main theories of the creation of the Earth are The Big Bang, Steady State, Evolution, and Pangaea Theory. First I will discuss the Big Bang Theory. Georges LemaÃtre proposed the Big Bang theory in the 19th Century. ... Like the Big Bang Theory of LemaÃtre , Steady State is based on philosophical premises, not scientific ones. ...
