Third astronomers could not actually see the comic background radiation. The last evidence concluded the theory of the universe beginning that Stephen Hawking said “It is discovery of the century if not of all time. According to the big bang theory they say that universe began by expanding form “Infinitesimal volume with extremely high density and temperature.” The big bang it not a explosion. Scientists believes that they think even time began with the big bang theory. Today ever scientists believes in the big bang theory.
There is still many unanswered questions due to the big bang theory , but there is still many thing to discover and every day we are learning something new about our universe . Definitions: Supernova : “a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.”( Google ) COBE : is a satellite that was sent precisely for cosmology, sometimes referred to as Explorer 66.”The Cosmic Background Explorer”( Google ) Dark Energy : is a repulsive force that counteracts gravity and causes the universe to expand at a faster rate .
It is not yet possible to give a definitive answer to the questions: what was the Big Bang and why did it happen? However, there has been a great deal of speculation recently on this subject, and it may not be long before a definitive, or almost definitive, answer will be declared. For the moment we will simply take the Big Bang as it is given, a huge explosion in which time and space began expanding. It is important to realize that space itself originated in the Big Bang. IT is tempting to think of the universe before the Big Bang as being a vast, infinite, expanse of empty space, like the space between the galaxy clusters today.
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 Big Bang Theory Why is the Universe expanding? What is Cosmic Back Ground Radiation (CBR)? There are many questions asked about our Universe, which we know so little about. Scientists, in their attempt to answer these and other confrontations, have found one idea that seems to explain much of what we don't understand: The Big Bang Theory. An explosion of incomprehensible speed was the beginning of our known Universe and existence.
The Big Bang marks January 1st and is represented by a huge explosion on the upper left corner. The background of the first four months, the first row, transitions very smoothly from left to right as we observe the birth of the Milky Way galaxy with a background of hu... ... middle of paper ... ... brought the beginning of humanity. The cosmic calendar contains a lot of information for viewers to digest. As people scan from left to right, they are actually skimming through history. It seems as if we know the entire history of the universe, but we still are confused about why and how all the events in the last 13.8 billion years occurred the way it did.
How the Big Bang Evolved into Life On Earth Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started. The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density.
13.8 Billion years ago, long before the creation of the popular television show, The Big Bang Theory occurred and is now the most widely recognized cosmological model for the universe. The Big Bang theory is an attempt to explain how the universe we know today began. Over the years, numerous discoveries and research have revealed that our universe did have a beginning, and that there was nothing before the Big Bang occurred. Throughout history there have been other theories as to how our universe began, though the Big Bang still prevails. One of the most exciting parts about the universe is a vast and fascinating place and there are even new discoveries still being made today.
The Big Bang Theory There have been many theories concerning what the universe looks like, how it became this way, and where it is going. The most popular theory that people hold today is that the universe began when all the matter ever present in the universe was contained in a tiny speck and that spec exploded. This is known as the Big Bang. This theory has developed a great deal since it was first conceptualized and continues to evolve today. Many different scientists have had a hand in this.
The big bang is one of the most famous explanations to the creation of our Universe. In this scientific theory, all matter was just one point at the beginning of time. Then it exploded shooting matter and anti-matter out in every direction. Eventually this matter clumped together to create whole worlds and stars. This is a purely scientific theory about the origin of everything but it has its flaws.
