occur? Space and time were created in the Big Bang. At the beginning of the universe‚ the space was completely filled with matter. The matter was originally very hot and very dense and then expanded and cooled to eventually produce the stars and galaxies we see in the universe today. 6. What evidence supports the Big Bang Theory? The Big Bang is the leading theory that almost all astrophysicists believe explains the origin of the universe. This is because all observations so far made support

universe? To start off‚ I define the universe as all matter and energy that exists. Our cosmic address in the universe begins at our galaxy in the local group‚ which is an island of stars in space held together by gravity and all orbiting a common center. Besides our galaxy there are about 40 other galaxies in our own local group. Our galaxy‚ The Milky Way galaxy then goes on to our solar system. Within the solar system there are 100 billion stars‚ the biggest being the sun. The star is a large

the following questions thoroughly. 1. Name three forms of evidence used to support the Big Bang Theory. (9 points) 1. Recession of distant galaxies noted 100 years ago and confirmed in the 1920s 2. Cosmic microwave background discovered by accident in 1964 or 65. 3. Relative abundance of hydrogen‚ helium. lithium and boron as measured in other galaxies and even our Sun and other nearby stars is as predicted from theoretical studies based on hydrogen bomb research. 2.

And the red supergiants are one of the most known giant stars in the galaxy. The massive star is a stage before the red supergiant.The way a massive star is formed is by fusing material into more heavier elements.The

Micheal Introduction to Astronomy‚ PHSY 101 (sec.001) (Abstract) This was a film about if there were life form such as aliens‚ somewhere else in our world that are living organisms just like we have here on earth and if so where could they be found. What things should we search for out into the stars to find other sign of life‚ this film goes into detail and try to answer all of these

The curiosity humans have in our origin and worth has led to a remarkable search for answers to big questions about history starting from the very beginning. Big history cosmology looks to answer some of the biggest questions humans have about the universe. In this paper‚ big history will be explored through the formation of the current U.S. one cent coin or more commonly referred to as a penny. The big bang theory is a scientific origin story‚ based on real evidence which explores history in thresholds

They named the source Sagittarius A* (Sagittarius A star) but they

If you have been doing much reading on astronomy‚ you have probably come across the term "red shift". When astronomers are explaining how far away a distant object is‚ they will usually say something like "The red shift of the galaxy (or other object) indicates that it is about 4 billion light years away". What does "red shift" mean‚ and how can it tell us how far away an object is? Since most of the things we look at in the sky are so far away‚ we cannot visit them and find out what they are made
