Beggining of Earth Theories

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. What most people don’t know is that there are two other theories that are widespread in the science world. 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 Lemaítre proposed the Big Bang theory in the 19th Century. He proposed that 15 billion years ago a big bang occurred, creating the universe. The universe began as an infinite dense, hot fireball, scrambling time and space. Within the first second of the universe coming into existence, gravity came into being. The universe expanded rapidly and became flooded with subatomic particles that slammed into each other creating protons, and neutrons. According to scientist three minutes later, when the temperature reached a blistering 500 billion degrees Fahrenheit, protons and neutrons formed the nuclei of hydrogen, helium, and lithium the simplest elements.

It then took another 500 thousand years for atoms to form and an additional 300 million years for stars and galaxies to begin to


Those individuals who have traits that help ensure their survival are more likely to have offspring, which will inherit the same traits. Yet offspring are not identical to their parents, there is always room for a mutation or genetic variation. Variations that enhance an organism’s capacity to survive and multiply will take over and supply less variation in population. Over long periods of times, often millions of years the cumulative effect of the favorable variations in a given population most lead to the evolution of new species.

There are two main discoveries that support the Big Bang Theory; one is an observation made by Edward Hubble in 1929, and Arno Paerzias and Robert Wilson made the second in 1948. Hubble observed that stars existed in huge groups called galaxies. By tracing the light of those stars, he also found that all matter in space is moving away from each other. Thus, proof the universe is expanding which further supports and explosion of some sort hence the Big Bang. Paerzias and Wilson made the second observation in 1948, it was this. Physicist George Gamow stated that if the Big Bang Theory was true the energy emitted during the explosion would in turn produce a humongous amount of radiation that would be measurable even to this day. This is true due to Planck’s law that states that all bodies emit energy that can be documented on an electromagnetic diagram. So when Paerzias and Wilson discovered traceable amounts of radiation all through the sky it was more support for the Big Bang. Big Bang is the most supported theory of the creation of the universe, and is believed widespread throughout the science scene.
