My topic is on Cosmic Microwave Background Radiation (CMBR). It is a really low glow of light that fills the Universe. It could only be detected by using a radio telescope. When you look up at the night sky all you could see is the stars and the darkness behind it so when you use a radio telescope you could see some kind of glow in the sky instead of blackness. It is an afterglow made by the Big Bang and it left the CMBR behind as evidence. Long ago before the stars and planets were formed, the
universe is continually expanding. The big bang theory has evidence to support it. An example of this evidence is the cosmic microwave background. The cosmic microwave background was discovered in 1964. The cosmic microwave background is radiation left over from the beginning of the universe or the big bang. This background is important because the radiation is the type of radiation that was seen at the beg...
mission to provide answers to how the universe began, how it transformed, and how will it continue in our future. Planck’s goal is to measure the remnants of radiation that filled the universe, CMB, with even greater accuracy than the COBE satellite. Smoot Became involved with Planck since its inception in 1992, it held the Cosmic Background Radiation Anisotropy Satellite (COBRAS) that led to a more definitive examination of CMB. George Smoot’s discovery of the blackbody form and anisotropy of CMB, has
something that he could not see was there, causing this; he dubbed this dark matter. However, Zwicky was ridiculed for this idea. In the 1960s, Kent Ford designed what is now called a spectrograph, a device that disperses electromagnetic radiation, making the radiation visible to the user. This innovation allowed Ford and Vera Rubin to observe the orbital speeds of stars and gases in galaxies from different distances from the central black hole of that galaxy. When doing so, Rubin observed that the
The big bang theory reveals the beginning of the universe. It states that the Universe was formed about 14 billion years ago for a giant explosion of very dense and hot matter which then expanded and as it expanded, it started to cool down by going through different transitional phases. Since, it has been expanding. The Big bang theory has the answer of every creation in the universe. The big bang theory states, all the matter that are present in the universe came to existence at the same time of
The Big Bang Theory according to National Geographic was a massive blast that had occurred 10 to 20 billions of years ago. It allowed all the universe’s known matter and energy, including space and time to evolve from an unknown type of energy, that has only been unraveled up intill the big bang. The theory believes that at the instant of that very second after the big bang had happened, the universe started to increase at an unclear rate of speed, that has not never been recorded. From what was
temperature caused a big “bang”. To current cosmological theories was the event that caused the universe. There are abundant pieces of evidence that support the Big Bang Theory, including redshift of galaxies and an expanding universe, cosmic microwave background radiation, and the abundance of elements from the Big Bang. The first piece of evidence
INTRODUCTION Since the beginning of time, people have wondered about why we are here, how we got here, and where we came from. Although many of these questions have not been answered, the question of where the universe we see today came from has been answered, or at least answered as well as possible with the technology available. Currently the leading theory for the origin of the universe is the Big Bang theory. Although some scientists still dispute this model for the development of the universe

that other galaxies were moving from earth at a high speed in different directions. This theory was further boosted by the Arno and Penzias Wilson’s discovery of cosmic microwave radiation, which is believed to be the tangible remnant leftover light from the big bang. According to this theory the universe, all of its matter and radiation was compressed into a hot, dense mass, which was very small. However, the theory states that there was a blast which enabled all of universe’s matter and energy to
The Success of the Big Bang Theory At the beginning of time, there was nothing. In a sudden “bang”, the entire Universe and all of the energy in it began to expand outwards from one point. According to many scientists, this is how the Universe began. This theory is known as the Big Bang theory, and it is one of the most widely accepted explanations for the origin on the universe, both among scientists and ordinary people. Part of the theory's success is the strong evidence supporting it; however
universe is thought to have come from a singularity which is said to have a extreme heat in it, it was believed that there should be a background heat still in existence in the universe. In 1965 two radio astronomers, Arno Penzias and Robert Wilson, discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) that is spread out across the universe. This is believed to be remnants of the extremely high-temperature from the big bang.
theory makes its own predictions regarding the exact distribution of fluctuations of the cosmic microwave background, which have so far been confirmed, though complete confirmation will have to wait until the MAP and FERMI satellites become operational later in this decade. The bottom line is that historical sciences (in this case, cosmology) can make testable predictions: the existence of background radiation and its properties, the distribution of light isotopes, the presence of galaxy evolution
of Astronomy I wasn’t sure what to believe. But after sitting through the class I started to realize that all the pieces are starting to fit together like, why the galaxies are increasing in velocity away from us and also explaining the cosmic background radiation. About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed
energy than when it entered. These findings make dark energy completely independent of the supernova observations. Astronomers have found the first direct evidence of dark energy in the afterglow of the Big Bang, the radiation caused by the Big Bang called cosmic microwave background (CMB). The cosmi...

The Big Bang Theory is one of the most important, and most discussed topics in cosmology today. As such, it encompasses several smaller components that attempt to explain what happened in the moments after creation, and how the universe we know today came from such a fiery, chaotic universe in the wake of the Big Bang. One major component of the Big Bang theory is nucleosynthesis. We know that several stellar phenomena (including stellar fusion and various types of super novae) are responsible for
steady-state model. The discover of radiation in microwaves hurt the steady-state theory. Following World War II, Martin Ryle led a study at Cambridge in which he tested over 2,000 different radio sources from outside the Milky Way, and he concluded that the different radio sources showed a different distribution, thus supporting the Big Bang theory (“Big Bang” 1). In the early 1960s, Robert Dicke of Princeton University verified Gamow’s idea that there was a microwave background in the sky consistent with
The Big Bang Theory is “the beginning of space, time, matter, energy and the expansion of the Universe.” The Universe started off as a small point in the middle of nowhere. It was around ten billion degrees less than a second after starting. As everything expanded and got pushed apart, it all started to cool down. As the particles formed together, they created atoms. Over time, the atoms grouped together so much that they started making stars and galaxies. After an even longer time, the atoms started
Jersey, possibly found evidence of the Big Bang in 1965. These astronomers detected background “noise” in their satellite transmission system called “Echo” at the microwave frequency from every direction, in which they concluded to be a cosmic frequency resulting from the big bang that created the universe. These men won the 1978 Nobel Prize in Physics for this “discovery of cosmic microwave background radiation.” On the other end of the debate, people argue that there was a... ... middle of paper
