Dark matter

Dark energy is a term scientists use to describe the unknown source of energy which causes the universe to accelerate outwards rapidly, causing the known universe to expand. This is another concept which is directly applicable to the theory of increasing…

Universe is Expanding?, Live Science). Hubble discovered that there was a relationship between the red shift, also known as the cosmological shift in the spectral lines from the galaxy and the distance to an remote galaxy. Scientists also found that dark energy is the name given to the anti-gravitating influence. This is why there is an accelerating rate of our universe expanding. Even though this seems right, there have been other theories. The first theory as you know is that the universe will…

The crucial element that needs to be improved upon with crew safety lies within the area of bacteria of celestial bodies, but from space itself. Mankind has never been in contact with these bacteria that originate from other celestial bodies, and the consequences of encountering these forms of bacteria are unknown. The safest and most logical concept is to improve upon all the shielding from space, to create as little contact with the forms of bacteria as possible (Krishen 5). Another area 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…

essay is dark matter’s importance on galaxy formation. I chose this topic because the notion of dark matter piqued my interest. It’s non-luminous so it cannot be directly observed by a telescope, which prompted me to learn more about the topic and understand it on a deeper level. Outline Introduction In this stage, the topic will be introduced, as well as a brief introduction of the subtopics that will be addressed. However the bulk of this stage will be dedicated to discussing dark matter and…

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…

me, but it probably scares and excites scientists studying it all over the world. Since we only know a fraction of the inter-workings of the universe, there are many questions and things going on that we simply have no answer for yet. Dark Energy darkenergy-1 Dark Energy is the unknown force/energy that takes up around 70% of the universe. Sure, you look up and see billions of stars, but there's also the space between those stars and the effect it has on them that puzzles scientists. It's…

go. 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…

formed around 13.5 billion years ago after the big bang and the dark ages. NASA states that, “After the Big Bang, the Universe was composed of radiation and subatomic particles.” There are two theories about what happened next. The first theory is that small particles slowly team up and gradually form stars, star clusters, and eventually galaxies. The second theory states that the universe first organize as immense clumps of matter that later subdivided into galaxies. Milky Way The most known…

used a method different than most star gazers of the time. He mapped out the stars in relation to each other, instead of the traditional grid method used at the time (Smith 2013). He started out by studying the Society papers on natural history and matter theory, after he joined the Bath Philosophical Society in 1780. He also reached out to the experts of the time Joseph Priestley and John Mitchell on proper construction of astronomical telescopes. After he did his research, he started his…
