The paradox Olbers Heinrich Wilhelm Olbers German astronomer by 1826 in formulated physical paradox that was previouslyJohannes Kepler (1610 in), and Halley and Cheseaux (the 18th century described) as well. The paradox is that if the universe is infinite, we'd have an infinite number of stars light of the result The combination of the sky at night it should be clear to all.However, experience to the contrary. [1] Assumptions [edit | edit source text] If 1. the universe is infinite, 2. an…

of this is the following: the nearest galaxy to the Milky Way is called the Andromeda Galaxy. It is just over two and a half million light years away, which means that the light we see from there is just over two and a half million years old because this is the distance between us and the Andromeda Galaxy. Now imagine those numbers written out. Wait, don’t even attempt it, I’ll write them for you. The nearest galaxy to our Milky Way is the Andromeda Galaxy. It is just over…

John Sinclair Dr. Philip Carlson General Physics I 11/28/2015 Physics Worldview Paper 6.67408 × 10-11 m3 kg-1 s-2. This number is the universal gravitational constant. It is an empirical physical constant denoted by the capitol letter G. The gravitational constant was first used in Newton’s law of universal gravitation [1] which states that any two bodies attract one another with a force which is directly proportional to the product of the two masses, and inversely proportional to the square…

In the endless reach of the universe, there was a star known as Arcturus. One day, she fainted and was taken to the hospital. The doctor diagnosed her with “Red Giant Star" syndrome, an outcome of her being with an iron child. The doctor advised her that due to her condition, if she chose to continue to fuse silicon into iron- to nurture her iron baby- she would get too hot and she could potentially collapse. Back in the day, Arcturus was able to combine hydrogen into helium particles in a…

Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

Uranus is the seventh planet of our Solar System for which scientists have about information due to the distance from this planet and Earth (a minimum of 1.6 billion miles [51]). Up until recently, our ability to observe it from afar was near non-existent. This icy gas giant experiences periods of day and night which last for 42 Earth years due to its 110 degrees axis tilt [14]. Uranus is not as stormy as Jupiter or Saturn, but within the 'Spring' section of the plant, where both cold and warm…

are letting astronomers see a peek of a few faint galaxies that could have occurred as far back as 600 million years before the Big Bang. These tiny galaxies could have possibly played a large part in cosmic reionization. Rachel Livermore an astronomer at the University of Texas at Austin says “That when they detected galaxies as faint they did it supports the idea that a lot of little galaxies reionized the early universe and that these galaxies may have played a bigger role in reionization…

The article, “Our Universe could be reborn as a bouncing baby cosmos” by Lisa Grossman suggests that there may be a new theory to how the universe began, that seems to be more accurate than the current theory. This new theory created by Neil Turok and Steffen Gielen is the new Big Bounce model; not to be confused with the older big bounce-big crunch model. This model, unlike all other past contenders, has been able to begin the first steps in an accurate description to how the universe…

How do stars form? The stars were born among the dust and scattered throughout the most galaxies. There is an example of dust cloud which is the Orion Nebula.The turbulence in the depths of these clouds produces enough mass of knots.Because its own gravitational attraction,and the gas and dust can begin to collapse. Then the material at the center begin to heat up which is known as protostar . The heart of the collapsing cloud will one day become a star. Since stars are formed from…

the National Academy of Science urged the construction of such an instrument. The report said that a large orbital telescope would make a "dominant contribution to our knowledge of cosmology," by helping scientists study stars, measure distances to galaxies, and investigate the physics behind our universe.” -from http://history.nasa.gov/hubble/ “NASA” For decades, they spent all types of time and money for making this outer space telescope proposed by Spitzer. After the designing, building and…
