For almost one hundred years‚ we have known that the universe is expanding. We have traced this expansion back in time‚ through to the very beginning when the universe occupied an infinitesimal point in space. This was the state of the universe at time t=0‚ over 13 billion years ago. It is from this starting point that everything we are familiar with came into existence: protons‚ neutrons‚ stars‚ galaxies - even space and time itself are here. At time t=0‚ this point began an unprecedented inflation

Origins of the Universe 1.Identify the current theory of the formation of the universe. The big bang theory. 2.Describe the Doppler effect. The Doppler Effect is when waves moving away from you have a longer wavelength (lowpitch) and waves moving towards you have a shorter wavelength (high pitch) 3.Explain how the Doppler effect gives us information about the movement of stars andgalaxies. Stars moving away from us are red shifted (light of longer wavelength) while stars movingtowards us are

Humans live on a small planet in a tiny part of a vast universe. "This part of the universe is called the solar system‚ and is dominated by a single brilliant star-the sun." (Skywatching 230) The solar system is the earth ’s neighbourhood and the planets Mercury‚ Venus‚ Mars‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto are the Earth ’s neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago‚ perhaps when

Large Scale Universe to Milky Way SCI/151 07/07/12 Cosmology‚ as defined by Encarta Dictionary is “the philosophical study of the nature of the universe.” This concern with viewing the universe and its vast issues and meaning takes the mind into a mysterious spectrum. The very foundation of Cosmology began with Astronomer Edwin Hubble in 1929. He discovered that other galaxies existed in the universe and determined that these galaxies were moving away from each other at a rate that was constant

The Big Bang In cosmology‚ the Big Bang is the scientific theory that describes the early development and shape of the universe. The Big Bang Theory is the most accepted theory for the origin and evolution of our universe. The big bang theory states that at some time in the distant past there was nothing. It suggests that around 10 to 14 billion years ago‚ the part of the universe we can see today was only a few millimetres across. According to this theory‚ at the beginning of time‚ all of the

However‚ it is the concept of heat death was the first step to realize the possible finiteness of the Universe‚ although we do not know when and on what scenario will happen of its destruction. At the present stage of existence (13.72 billion years)‚ the universe radiates as a
