The Cosmic Microwave Background Or Cmb

Cosmic background radiation is radiation from the early development of the universe. After the big bang the universe was smaller and much hotter than it is now and was filled with a fog of hydrogen plasma. Eventually the universe started expanding and became cooler. As it cooled stable atoms started forming, leaving only CMB remained so it is a strong evidence that the Big Bang Theory was correct. Scientist thought if the big bang actually happened then there would have to be cosmic background radiation left over, so all they had to do is find evidence of this and they did so this gave the big bang theory evidence to support their claim.

The article ‘On the Recentness of What We Know,’ written by Verlyn Klinkenborg, is a pleasant read about the author’s fondness of astronomy and his insight regarding the science of it and knowledge gleaned from it. Klinkenborg recounts a few of his star-gazing memories and then proceeds to analyze the effects cosmological discoveries have on him personally and humanity in general. The author shares bits of theoretical history of the universe and information on the early astronomers whose hypotheses have developed that history. He goes on to reference various well known discoveries throughout the years and marvels at how drastically information in recent years has changed the stories of our universe.

These ideas not only, obviously, created a new conception of the forming of the universe, but also of humanities place within it. The Copernican hypothesis had enormous religious implications as it destroyed the idea that the earth was different from where God was. This eliminated the realm of perfection. Therefore humanity’s place within the Earth was lessening in importance. Also, 1572 a “new star,” which was really an exploding star, left a huge impression on many people. This is because it contradicted the idea that the heavenly spheres were unchanging, thus

“The lights that filled the universe could be channeled, dissected, magnified, and measured by human ingenuity” (enlight, 2). There was a significant breakthrough in regards to what could be done in continuing to explore new theories.

The currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state.

was made and that for the next half-century politicians strived to in fact discover what

The Big Bang started off as energy, deep into the darkness because light didn’t even exist neither did gravity and the universe was never even created. The energy expanded and the temperature got intense and then started to expand. This is what cause the universe, millions of galaxies, stars, and solar systems. Scientists discovered that the space in the Universe was expanding and what cause this was the Big Bang. The evidence can be proven wrong but because of this, what had caused the red shift that was heard in the sky? Scientists believed that the red shift was caused by the Big Bang that was 14 billion years ago.

Dark matter is an element which is non-luminous and cannot be identified directly by electromagnetic light but can be identified. Dark matter is believed to be the fundamental element that makes up the universe, and that could probably be the reason why it is difficult to separate it from other particles.

There have been many theories concerning what the universe looks like, how it became this way, and where it is going. The most popular theory that people hold today is that the universe began when all the matter ever present in the universe was contained in a tiny speck and that spec exploded. This is known as the Big Bang. This theory has developed a great deal since it was first conceptualized and continues to evolve today. Many different scientists have had a hand in this.

Toward the latter part of the 17th century, a complete new view of the universe came into being. With the publication of Newton¡¯s ¡°Philosophiae Naturalis

At the present stage of existence (13.72 billion years), the universe radiates as a black body with a temperature of 2,725 K. Its maximum to the frequency 160.4 GHz (microwave radiation), which corresponds to a wavelength of 1.9 mm. It is isotropic up to 0,001% - the standard deviation of temperature is

The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000

Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related.

This observation means that it has taken every galaxy the same amount of time to move from a starting position to its current position. This observation is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this in 1929. Edwin Hubble’s evidence supports the expansion of the universe and suggests that the universe was once compacted. Third, if the universe was insanely hot as the Big Bang suggests, scientists should be able to find some of this heat left over. In 1965, Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin Cosmic Microwave Background radiation which infuses the observable universe. This is thought to be the remnant that scientists were looking for. Finally, the discovery of great amounts of Helium and Hydrogen lead to support the Big Bang Theory. (LaRocco)

Once microwave radiation was discovered, studies improved on the Milky Way Galaxy. Its Doppler Shift can be used to map the motion of gas in it. Also, with radio telescopes, hydrogen gas can now be traced. When the Hubble Space Telescope was introduced in 1990, that made exploring space so much easier and more efficient. That’s how we discovered so much about our universe- including galaxies!
