Another conundrum thrown up by the basic big bang theory is how to explain the relative homogeneity and evenness of the temperature of the cosmic microwave background radiation. With science under attack so much, astronomy has been getting its share of the flak because of this, some of the bigger ideas are getting hit, from the big bang to star formation to stellar (gasp. Chapter 5 shows why gamow's big bang theory came to be accepted rather than hoyle's steady state theory the history of how the overwhelming evidence from radio astronomy's discovery of the cosmic background radiation is beautifully presented and how many other observations now support the big bang.
These are known as the 4 pillars of the big bang theory four independent lines of evidence that build up one of the most influential and well-supported theories in all of cosmology. The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang this theory was born of the observation that other galaxies are moving. The big bang theory states that around 12-15 billion years ago the universe came into existence from one single extremely hot and dense point, and that something triggered the explosion of this point that brought about the beginning of the universe.
The big bang theory is the prevailing theory of the origin of the universe, and it is based on astronomical observations according to this theory, about 15 billion years ago all the matter and energy in the visible universe was concentrated in a small, hot, dense region, which flew apart in a gigantic explosion. The big bang theory is a very well tested theory a large quantity of data, coming from wildly different types of observations (see chapter 2 ) give an internally consistent picture of the geometry, composition and history of the universe. The big bang theory is not really a theory about an explosion that name was given to the theory by an early opponent of the theory nevertheless, we have seen that there are many justifiable accusations to level at the big bang theory, such as its reliance on fiddle factors, like dark matter.
On monday, dr guth's starship came in radio astronomers reported that they had seen the beginning of the big bang, and that his hypothesis, known undramatically as inflation, looked right. The big bang theory explains how the universe has evolved over last 138 billion years, starting from a singularity to its current size astronomy cast has also has several relevant episodes. The universe is a very big place, and it's been around for a very long time thinking about how it all started is hard to imagine this meant that the universe was still expanding, just like lemaître thought if things were moving apart, it meant that long ago, everything had been close together.
The big bang theory is an american television sitcom created by chuck lorre and bill prady, both of whom serve as executive producers on the series, along with steven molaro all three also serve as head writers. About the author dean a kowalski is an associate professor of philosophy at university of wisconsin-waukesha and the author of five books, most recently moral theory at the movies and the philosophy of joss whedon. The big bang model successfully accounts for the formation of the light elements, hydrogen, helium and traces of lithium and their isotopes from fundamental particles elements heavier than helium, including the iron, carbon and oxygen in our bodies and the uranium in the earth were all synthesised later in stars. This is for our project in school, hope you all enjoy it ^.
Big-bang model, widely held theory of the evolution of the universeits essential feature is the emergence of the universe from a state of extremely high temperature and density—the so-called big bang that occurred 138 billion years ago. The big bang theory may be nice but it has to pass the judgement of observation nature and experiments are the final judge of the correctness of scientific ideas though some details of the big bang still need to be perfected, the general scheme of an early hot universe with a definite beginning is accepted by most astronomers today. The big bang is the dominant (and highly supported) theory of the origin of the universe in essence, this theory states that the universe began from an initial point or singularity which has expanded over billions of years to form the universe as we now know it in 1922, russian cosmologist.
