How Does Dark Matter Exist

In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light.

The Economist’s article “The most beautiful theory” discusses Albert Einstein’s theory of general relativity. It explains the origins of general relativity through Einstein’s initial thought experiments that eventually led to the realization that the university functions in four dimensions (“three spatial dimensions, one temporal one”) and that mass curved space-time, creating gravity. Over time, Einstein’s theory was verified by observations, such as those made by Arthur Eddington when he noticed the skew of light around the sun during an eclipse, which could only have been due to distorted space-time. His theory has also been expanded over the years as physicists try to combine general relativity with

Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

Dark Matter is a very interesting book that I would recommend you to read. The author of Dark Matter has both assimilation and tolerance in the book. In the book tolerance is used by Jason having to survive in different situations. At one point in the book he goes to a world that is covered in snow. He built tolerance to the cold and was able to carry Amanda to a cabin and survive. But also has assimilation sprinkled in. Jason had to adapt to his doppelgangers and their worlds.

Gravitational lensing is basically where mass bends light. If light rays pass close to a massive object it will pretty much be reflected and shown somewhere

We look for things that we can’t see by looking through special powerful telescopes that help us see the things we can’t from the naked eye. Many special telescopes today at NASA are those that can see things our eye itself cannot. These telescope’s lenses are the most powerful in the world. They see things our eyes can’t like dark matter. Like when dark matter was discovered. W. Kent Ford confirmed the existence of this “missing mass”. He observed a resembling phenomenon. The mass of the stars visible in a typical galaxy is about 10 percent required to keep stars orbiting their galaxy's center. Speed with which stars orbit the center. Accoring to http://www.britannica.com/science/dark-matter “Indeed, orbital velocity is either constant or

If we find evidence of Dark matter it will help us understand the universe much better. It may even tell us what the universe was like one tenth of a second after the big bang. When we find out how our universe is formed, we find out more about how our solar system is formed, and how life, sentient or not, came to be (The Universe). We first started thinking about Dark matter in the 1920’s.

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

Through wonder and complicated thinking Einstein gave a strong argument on how space and time could be curved. By Einstein creating this theory he completely altered the way we could think of space and time. Einstein pictured space as a three-dimensional version of a thin rubber sheet. If you put a heavy object on the sheet, it makes a dent, and therefore an object's path would be affected by that dent. So, planets orbit the sun because “the space around the sun is curved in the 2-D equivalent of a funnel or basin”.( http://burro.astr.cwru.edu/stu/20th_people_einstein.html) “The curvature of space results in the effects of gravity. This notion of curved space becomes more tangible . . . occurs because its curvature of space”. (http://www.fi.edu/learn/case files/einstein/curved.html) Einstein introduced this special theory of relativity because it dealt only with the special case of motion in frames of reference that are neither increasing nor decreasing to the viewer. In other words, “the frames of the reference are . . . a consistent speed in a straight line”. (Jake Goldberg pg.47) Einstein also changed how we now think about gravity itself! He came up with his own theory of gravity as well, called Equivalence Principle. “Einstein said that when he was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me: 'If a person falls freely he will not feel his own weight.' I was

The particles include photinos, neutrinos, gravitinos, axions, and magnetic monopoles, among many others. Of these, researchers have detected only neutrinos -- and whether neutrinos have any mass remains unknown. Experiments are under way to detect other exotic particles. If they exist, and if one has a mass in the correct range, then that particle might pervade the universe and constitute dark matter.

Black holes are one of the most mysterious aspects of the Universe. Scientists know that black holes contain an insane amount of matter packed into a small space with a gravitational field so intense that not even light can escape it. This review will focus primarily on what is known about black holes, how scientists know black holes exist, current studies and experiments, and why they are studied. Based off the knowledge humans have already uncovered about black holes, they could change the future. Black holes could realistically be used to power starships, enabling humans to travel at near light speed to explore the Cosmos. Humans would be able to conquer the most unknown frontier yet.

General Relativity is a two part theory created by the German physicist, Albert Einstein. The two sections of relativity is special relativity and general relativity. Special relativity focuses more on lines, constant-velocity motion on the mass of objects, the passage throughout time, and that passing the speed of light is impossible. General relativity deals with accelerated motion, gravitational fields on mass, size, and time. General relativity also states that matter and space effect each other and that the universe ends and there may be more universes out there. Relativity also includes space-time. Many people think that space and time are completely different variables, but physicists often combine them into “space-time”. Space-time is a four-dimensional coordinate system used in relativity and other areas of physics. The dimensions are, length, width, height, and the 4th is the time dimension.

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.

Allan Poe states in his essay on cosmology titled Eureka, that “space and duration are one.” To many, this is portrayed as the first known instance of suggesting space and time to be joined together as one thing. Albert Einstein's 1905 theory of special relativity is the very beginning of a theory related concept of spacetime, but the first mathematical theory of spacetime actually created by one of his own early teachers named Hermann Minkowski. He created the concept of “Minkowski Space” which is the earliest recommendation to the treatment of space and time as two separate entities of one unified whole. The idea of Minkowski space has led up to special relativity being viewed more so in a geometrical way rather than a scientific and mathematical way. Minkowski space is described as the mathematical formation for which special relativity can be conveniently formulated. In this setting the three dimensions of space are combined with one dimension of time to create a four-dimensional whole expressed together as spacetime.
