Cosmic Microwave Background (CMB): This is the result of theorized energetics, which was discovered in 1965 by Penzias and Wilson. Their discovery showed microwave radiation emanating from all directions in our observable locality of the universe. As predicted by the Big Bang Model, the universe is filled with plasma at high temperatures. As a result, hydrogen can only exit as plasma with an ambient temperature of about 3000K.…
* Scientists noticed that all stars & planets are moving away from Earth which supports the theory that a massive explosion once occurred. (Big Bang)…
-The sun is located in one of the Milky Way's outer arms, about 25,000 light years from the galactic center.…
5. When did the Big Bang occur? Space and time were created in the Big Bang. At the beginning of the universe, the space was completely filled with matter. The matter was originally very hot and very dense and then expanded and cooled to eventually produce the stars and galaxies we see in the universe today.…
Earth and all other planets of our solar system orbit the sun; the entire universe is not Sun-centered.…
The creation of matter in the early universe was aided by the four fundamental forces, the strong force, the weak force, the electromagnetic force and the force of gravity. The standard model includes the three of the four fundamental forces excluding gravity and whilst it explains how these forces act upon the matter particles it is difficult to include gravity into its framework. In the early stages of the universe the temperatures were very high, thus the weak, electromagnetic and strong forces were unified.…
Observations of distant galaxies show that the universe is expanding by an average distance increase between galaxies. We are able to trace back at this rate to determine what we were all one universe and where the Big Bang might have started.…
When we look into outer-space today we see billions upon billions of stars the cover the “universe”, but what may have crossed your mind is how did they get there? Well before, these stars were there it was said that the universe was a very hot, small, and dense with no stars, atoms, forms “singularity”. The way that the universe became what we see today is what scientist calls “The Big Bang Theory” not to get confused with the show. Scientist base the Big Bang theory on many different factors/observations. The most important is the “redshift” of very far away galaxies. Redshift is the doppler reaction that occurs in light. When an object moves away from earth, it looks reddish because the movement stretches the wavelength. The reddish color occurs because; red is the lowest wavelength on the visible. The more redshift there is, the faster the object is moving away. By measuring the redshift, scientists proved that the universe is expanding and can even work out how fast the object is moving. Basically, what happened is that “space” became expanding very quickly about fourteen billion years ago, and which resulted in the formation of atoms, which eventually led to the creation of stars and galaxies. Space as we know it was created, and is still expanding at a very rapid rate while becoming much cooler.…
Cosmology is the study of the universe as a whole. Describe the foundation of modern cosmology.…
The Big Bang theory is the theory that there was ax explosion over 13.7 billion years ago that created space and time into existence. Before the big bang there was nothing. The universe is constantly expanding in a result of the force of the explosion.…
The universe has not always existed. It had a start...what caused that? Scientists have no explanation for the sudden explosion of light and matter.…
Professor - The Milky Way is the galaxy that contains the Earth. This name derives from its appearance as a dim milky glowing band stretching across the night sky, in which the naked eye cannot distinguish individual stars. The term Milky Way is a translation of classical Latin ____ from the Hellinistic Greek, Milky Circle. The Milky Way appears like a band disk-shaped structure being viewed from inside. The fact that this faint band of light is made up of stars in 1610 when Galileo Galilei used his telescope to resolve it into individual stars.…
14 billion years ago, the universe exploded from a singularity containing a lot of concentratedenergy. The energy converted into matter and antimatter. The universe expanded relativelyslowly, then within a fraction of a second, inflated a lot bigger at a very high temperature.When a matter and antimatter particle met, they annihilated, releasing a burst of energycalled a photon. After the annihilations, a small excess of matter was left over, which thenbecame the building blocks of the universe. Three minutes later, when the universe was 1billion degrees Celsius, quarks began to clump in threes to form protons and neutrons. Aproton is the nucleus of the simplest atom - hydrogen. A proton and a neutron formeddeuterium, which then formed helium. (77%hydrogen, 23% helium)…
The most accepted theory is the Big Bang – a cosmic explosion that caused the world to exist. Before the Big Bang there had been nothing except an amount of matter that was smaller than the eye of a needle. The explosion caused this to expand and thus; our Universe was created. Scientists believe that it is still expanding, and will one day stop, and begin to contract. They have also found slight ripples of cosmic radiation to prove this.…
The curiosity humans have in our origin and worth has led to a remarkable search for answers to big questions about history starting from the very beginning. Big history cosmology looks to answer some of the biggest questions humans have about the universe. In this paper, big history will be explored through the formation of the current U.S. one cent coin or more commonly referred to as a penny. The big bang theory is a scientific origin story, based on real evidence which explores history in thresholds from the big bang to present. Thresholds are time periods that break up history into sections and each one is marked by significant pivotal events and emerging properties. Each threshold is connected to the last and accumulated ingredients led…
