the afterglow of the Big Bang‚ the radiation caused by the Big Bang called cosmic microwave background (CMB). The cosmic microwave background is hotter in spots where there are more galaxies in a cluster. Dark energy is also‚ what keeps space flat. Not until to long ago‚ there was an inconsistency between the matter in space‚ the energy in the universe‚ and the flatness of space. Scientist studied the cosmic microwave background and a large-scale structure‚ and they were able to conclude that the

Assignment 7 Chapter 24: 1. When was the first quasar discovered? The first quasar was discovered in the 1950’s. 2. What is the theory of the existence of quasars? In 1965‚ Jim Gunn and Bruce Peterson of Caltech predicted that distant quasars should show evidence of the end of the cosmic dark ages. But until recently‚ no one had ever seen an object distant enough to check their prediction 3. Where can we find quasars and what are the main characteristics? Quasars have little or

English 102 Report The Big Bang Theory By Faisal Al-Saeed ID: 201051280 102-60-22 Mr. Nicholas Table of Content Big Bang Theory Introduction At the beginning of the 20th century‚ physicists generally had a strong bias toward the idea that the universe was essentially unchanging. However ‚this theory does not fit with the universe phenomena which change from minute to minute‚ and stars and galaxies might be born and die .In this report ‚ we will look at one of the famous

Big Bang From Wikipedia‚ the free encyclopedia "Big Bang theory" redirects here. For the American TV sitcom‚ see The Big Bang Theory. For other uses‚ see Big Bang (disambiguation). According to the Big Bang model‚ theUniverse expanded from an extremely dense and hot state and continues to expand today. A common analogy explains that space itself is expanding‚ carrying galaxies with it‚ like spots on an inflating balloon. The graphic scheme above is an artist ’s concept illustrating the expansion

A Brief History of Telescopes 1608 AD – Hans Lippershey‚ German-born Dutch lens maker‚ applied for a patent for his refracting telescope (using 2 lenses)‚ he intended them for use in the military. 1609-1610 – Galileo Galilei built his own refractor telescopes to observe the sky‚ and discovered Saturn’s rings‚ Jupiter’s moons‚ and along with many other significant discoveries. 1655 – Christian Huygens‚ a Dutch physicist and astronomer developed powerful lenses for refractor telescopes with his

The Big Bang theory offers a comprehensive explanation for a broad range of observed phenomena‚ including the abundance of light elements‚ the cosmic microwave background‚ large scale structure‚ and Hubble’s Law.[3] As the distance between galaxies increases today‚ in the past galaxies were closer together. The known laws of nature can be used to calculate the characteristics of the universe in detail back

The first piece of evidence that they had for the big bang was that they soon realize that the universe kept expanding. The second piece of evidence that they had about the big bang was The cosmic microwave background radiation. These two pieces of evidence support the big bang theory because they led to the conclusion that the big bang did occur. This big bang evidence helps us understand that the big bang made the universe expand every day. The most
