To this day stories, theories, beliefs, and much more have been created to simply satisfy our understanding on how the universe was created. Curiosity has been the key for all these definitions and through generations of humans many questions have been asked on the lines of How did our universe begin? How old is our universe? How did matter come to exist? However, these are very complicated questions that we to this day have no confirmed answer to but our history on this planet has lead to some clues that can possibly be the answer. Our history on this planet will be the reason why we answer these questions. The study of cosmology and modern science has lead to scientific theories that involve natural science it wasn 't just some created belief …show more content…
New possibilities opened up in 1915, when Einstein formulated his famous theory that describes the nature of space, time, and gravity. This theory allows for expansion the fabric of space. In 1917, astronomer Willem De Sitter applied this theory and showed that the universe could be expanding. This was revolutionary because accepted view at the time was that the universe was static in size. Also the universe was considered infinite at one point in time but the Big Bang proved that the universe had to have a history and a beginning. (2)According to Chris LaRocco and Blair Rothstein article 15 billion years ago there was an explosion called the Big Bang that created the universe. This explosion contained all the matter and energy of space. Unlike other explosion like a bomb that throw fragments outwards the Big Bang filled in the space with particles of the embryonic universe. Before the Big Bang galaxies were clustered together but the explosion created space and foundation for the universe. Edwin Hubble is the brain behind the Big Bang he made the observation that the universe is constantly expanding. His discovery on galaxies velocity and distance proved the Big Bang Theory. His discovery was that the speed of a galaxy depends on there distance from earth. Meaning the the universe is …show more content…
It became a popular theory with improved evidence because of the discovery of cosmic microwave background.
By the end of the 1960s and 1970s cosmologists, scientists, astronomers, the public had finally accepted the theory. It was in the spring of 1965 that unexplained microwave radiation was found by (2) by two astronomers called Arno Penzias and Robert Wilson. They discovered a noise that was created in the origin of the explosion. The noise didn’t just come from one location to another, it came from all directions possible at once. It was learned that the noise was a radiation from the farthest points of the universe that had been left over from the explosion.
The Cosmic Microwave Background accord about 380,000 years after the Big Bang. Before then, the matter in the universe consisted of electrons and protons. The universe was covered by haze and light waves were being blocked by the haze. Eventually the universe cooled down enough for protons and electrons to produce atoms, creating an electromagnetic radiation that rush outward. This burst of energy is what Wilson and Penzias
