big bang

The start of our universe has caused much speculation through the many years of human existence. Many theories have been proclaimed through the centuries, though one in particular is the most popular throughout the scientific world. The Big Bang Theory is most widely known when it comes to the creation of the existing cosmos.

The Big Bang theory consists of the idea that the whole universe was compressed into an extremely dense and hot state. This state is theorized to have only been a few millimeters wide. It had existed for about a fraction of a second before expansion had started. A giant blast occurred ten to twenty billion years ago, which created the expanding universe. This explosion was caused by some unknown form of ancient energy. In a trillion-trillionth of a second after this explosion, the universe started to expand at an enormous speed. The universe is still expanding today, except at a much slower rate. At the point of the big bang, the temperature was approximately ten billion degrees Fahrenheit.

After the big bang, a variety of different particles began to form. In the very beginning, there were no particles; there was only an equal amount of antimatter and matter. As the cosmos continued to expand, new particles started to materialize. These new atoms were called baryons. . These new atoms were called baryons. Baryons consisted of photons, neutrinos, electrons, and quarks. These particles became the foundations of every diverse particle in our universe. Baryons had paved the way for the more common particles we know today, such as protons and neutrons. When the universe had cooled down a bit, protons and neutrons began to form. Protons and neutrons were classified in the category of hadrons. The protons and ne...

... help prove the Big Bang theory, such as Arno Penzias and Robert Wilson. Arno Penzias and Robert Wilson had discovered the existence of cosmic microwave background, which is basically early light leftover in our universe from the Big Bang. The Big Bang theory has a long history, and its discovery can be credited to two scientists and/or cosmologists.

The Big Bang theory has greatly altered the course of the scientific world within the last century. Before the Big Bang was theorized, many scientists believed that the universe was unchanging and static. The Big Bang theory has not only taught us how the universe had initially started, but also the age of our universe and the fact that our universe is still continuing to expand after the 13.8 billion years of its existence. The Big Bang theory has played a major role in the exploration and studying of our universe.
