Dark matter makes up roughly 23% of the universe, and is thought to be the cause of its expansion. Dark matter was first proposed by Swiss astronomer, Fritz Zwicky when he noted that galaxies are flying away to fast. He noticed that galaxies are flying away to fast that they should fly apart, dissolve under Newtonian Laws of Motion. He thought the coma cluster may be saved if it were 100x more matter than you can see. Theres two possibilities left. Newton was wrong or something was missing.…

Living Between Two Worlds Dayton Kwok Introduction As an American born Chinese, I’ve always had to switch between using English and Chinese. This is especially exacerbated since I lived in San Francisco, a city dominated by immigrants hailing from Southern China and Hong Kong. One moment I’m using English to talk to my friends, and the next moment I’m using Cantonese to talk to my family. My native language was English, but I also learned to speak Cantonese around the same time I learned to…

So far, my SCE has consisted of organizing and preparing for the start-up of this year’s National Art Honor Society chapter. In addition to inviting members to join and having our first meeting, I have been setting up for the upcoming induction as well as composing our bylaws to the NAHS constitution. As of now, I have not been able to work on my deliverable, as that project will come into play when the activities and events of NAHS begin for the school year. When those events begin in November,…

Each individual, whether they know about it or not, has this slot in the back of their conscience filled with this dark matter that, at any given moment, can be triggered and take over the more sensible parts of the brain. It is not a matter of possession. This darkness is inside of us all from the day we are born, and it only grows stronger the older we are. It is only a matter of whether a person is pushed far enough for it to be seen. People may go their whole life without this side of them…

Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word…

Conditions such as uncleared drainage canals and a swampy soil in Kemar’s landscape are favorable to mosquito breeding and habitation. 2. On a broader level, stagnant water, excessive reeds, and extreme heat can also play a role in the increased mosquito breeding. Specifically, tropical regions are typical breeding grounds for mosquitos thanks to acute water presence from rain. 3. Shanae’s illness could be caused by the increasing number of mosquitos she has been exposed to, some of which cary…

Time is a concept that for a long time was thought to be untouchable. This was until black holes were discovered. These collections of matter hold the seemingly supernatural effect to alter time as we know it. A black hole is a star that has collapsed and become so dense that it creates a gravitational field strong enough that nothing, not even light, can escape. When a star dies it leaves behind a very dense remnant core. If the core’s mass is more than three times the mass of the sun, the…

Rebecca McKenney Frontiers of Astronomy Mrs. Alburg 26 April 2017 Our Galactic Universe 1. Galaxies can be as large as a few thousand to several hundreds of thousands of light years across. 2. Astronomers, at the time this was released, believe that there are over a hundred billion galaxies in the universe. 3. It is estimated that a light year is 5.88 trillion miles. 4. Galaxies come in three different main type shapes. There are spiral, elliptical, and irregular. 5. Spiral galaxies…

Cosmos episode 13, “Unafraid of the dark”, begins by talking about the vast amount of scrolls and information that was kept in the library of Alexandria. Many of the books and scrolls were lost when the mob attacked and destroyed the library. This is shocking because of all the history of Ancient times that he's been lost due to the destruction of these books. Although we lost many discoveries, we as humans continue to learn new information about the universe. This begins the discovery of…

thanks to the Hubble Space Telescope, we now know that to be dead wrong. Our universe is, in actuality, speeding up in its rate of expansion! This left scientists puzzled; it went against almost everything they had thought. Since there is matter everywhere, and that matter has gravitational attraction, so why wasn’t…
