early universe should first be understood. The main points opposing the theory are based around a few aspects that will be defined in the explanation of the early universe. These points include inflation‚ dark matter and dark energy‚ the cosmic microwave background (CMB)‚ and red shift. The theory states that the universe sprung from a singularity an infinitely dense point. A process called inflation took over from there‚ and all the matter expanded exponentially from one very small point to something

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

that the Universe was eternal. Then five years later‚ in 1964‚ radio astronomers Arno Penzias and Robert Wilson discovered a microwave signal buried in their data. They attempted to filter out the signal‚ assuming that it was merely unwanted noise. However‚ they soon realized what the signal actually was; they had inadvertently discovered the Cosmic Microwave Background (CMB). The CMB had been predicted by a theory that few believed at the time called the Big Bang. This discovery was the first evidence

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

dark energy in 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

Lacking adequate competition‚ the popular prototype has dominated the metaphysics front for the past two decades even though much of its complications have been left unresolved. With the advent progress in cosmic microwave background detection‚ these unsettled loopholes are begging for answers. A successful model that seeks to replace the Big Bang notion must be ready to explain the past‚ present and future states of the universe in an efficient and unified manner. The
