The universe is an immense, vast sea of mysteries and information. Among this sea of mysteries is dark matter and dark energy. It has been said that more is unknown than known when it comes to dark energy and dark matter. These forces have puzzled and bewildered scientists for years. Dark matter and dark energy are complex ideas that lie within the universe and have intricate theories and formulas regarding them.
The cosmos, or universe, is filled with an abundant amount of matter and energy. Visible matter, such as the Earth and the sun, makes up less than two percent of the universe. Visible matter includes stars, planets, moons, comets, asteroids, etc.. Dark energy and dark matter makes up roughly about 95% of the universe. Dark energy is a theoretical force that counteracts against gravity thus making the universe expand at a quickening pace. “The only explanation for dark energy is that it is a property of space” (NASA, 2014). Dark matter on the other hand is

Albert Einstein was born on March 14, 1879 and passed away on April 18, 1955. This man is famous for his E=mc2 equation and his other scientific discoveries and theories. It is said that Einstein predicted dark energy and dark matter without even realizing it. Upon discovering dark energy and dark matter, “he realized that empty space is not nothing.” The first property that Einstein realized is that it is possible for more space to come into existence,” (NASA, 2014). Like mentioned earlier, dark matter appears to be the black backdrop to the beautiful stars at night. All of that empty, black space you see, is dark matter. Particles that are smaller than atoms, are alleged ingredients that make up this peculiar force. Other matter like black holes and additional objects are also included in that recipe. This recipe leads to a strange concoction. The main objective for dark matter is to squeeze the universe
Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them.
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.
Ever heard a bump in the night, or a whisper calling your name when you’re all alone? “The human mind makes up forces and tricks you into certain things” some say… But others think it’s something more , such as the paranormal? There are tons of different dimensions, who knows what’s out there that humans do not know about.
Since the 18th century speculation of unearthly life has been brought up by many influential people. One of the founding fathers of the United States, Benjamin Franklin, once stated "I believe that Man is not the most perfect Being but One; rather that as there are many degrees of Beings his Inferiors, so there are many degrees of Beings superior to him”. This quote justifies the fact that even the most prominent people believed in cosmic beings. Further in time, In July 1947, an unidentified flying object crash landed in a ranch near Roswell, New Mexico. What military officials discovered was nothing more than the debris of a weather balloon that was being tested. However, people did not seem to fathom the truth and began to investigate what the military did not want the public to know. Bodies of unknown humanoid beings were seized by the military and taken into a secret base for further analysis. Various reasons as to why celestial beings could lurk the universe are being brought upon by today’s modern science committee possibly unlocking an insight onto future life. The first reason as to why extraterrestrial life could perhaps exist is that there is a vast amount of galaxies, stars, planets, and solar systems that humans have not yet discovered. To think that humans, the only civilization on planet earth, are the only living organisms in space would be quite absurd. Furthermore, a second reason as to why extraterrestrials could subsist is that life thrives in the most extreme conditions. This means that whether organisms are in the depths of the ocean, in the midst of the ozone layer, or in the scorching hot temperatures of volcanos; life always finds a way to adapt. However, some may argue that life could not possible coin...
Throughout time, many stories and theories have been established by mankind to explain and understand the mysteries of the world. Among them, the idea that intelligent extraterrestrial life is one of the causes of these mysteries is a controversy still under debate. Many religions and traditions around the world have acknowledged other-worldly forces and “divine” beings arriving from the sky. In recent times, numerous sighting of unidentified objects, also known as UFOs, and aliens have been recorded and even documented possibly on planets other than Earth. Along with these strange observations are also scientifically unanswered abnormalities that have shifted the public
The prevalent theory today, describing the origin of the universe and where it all began is the Big Bang theory. Scientists believe that our almost 14 billion-year-old universe could at one point fit in the palm of one’s hand. In the beginning there was nothing. No space and no time but then came light. A tiny speck of light appeared and inside this tiny fireball was space – this was beginning of time. Time could now flow, and space could expand. The notion that everything in the Universe, all the matter, all the energy and all the galaxies were once contained in a region smaller than the size of a single atom today came from American astronomer Edwin Hubble in the 1920’s. He observed that other galaxies were speeding away from ours, and the further they were, they faster they seemed to travel. The Universe was therefore expanding and the Big Bang theory was born.
Throughout this course we have been learning about the expansion of the universe and it seems as if the universe will never stop expanding. There is so much that has yet to be discovered despite the fact that our ideas are evolving.
The Universe is something no one can explain. Our Galaxy is one of the countless galaxies dotted throughout the Universe, like islands in a big ocean. Many objects in the Solar System have yet to be discovered and may never be, but it will always be there and may never change for generations to come.
The universe was once a vast uncharted area; an area of the unknown. People looked up to the sky in wonder and awe, curious as to what was beyond Earth. What were those lights in the sky? Where did they come from? How did they get there? As time has passed, the universe made up of stars and planets has evolved. What we did not know before, we know now, our cosmos has changed immensely, transforming into what we now call our solar system.
Dark matter has been argued about for a long time about whether it helps or not helps the universe. The universe is mostly made up of dark energy at 71.4%, dark matter at 24%, and atoms a 4.6%. These are the statistics made about the composition of the universe. However, these statistics were not always none. Einstein himself said that the universe was static, that the universe was neither contracting or expanding. When the Russian Mathematician, Edwin Powell Hubble, proved him wrong, Einstein said it was his -greatest mistake-. However, the term Einstein used to explain the universe, the Greek letter lambda Λ), is still used today, but in a different way than he meant it to. It now is used as the term to describe the rate of expansion in the
Einstein published his theory of general relativity which stated that space and time were one and sort of like a cloth. He stated that the more mass an object had, the more distortion on space time it had. Einstein said that not even light could escape the effects of gravity. These opened contradictions to Einstein's beliefs though, and so he concluded the universe must be expanding or contracting. Einstein couldn’t make the leap, but others could. An expanding universe fit very well into a theory called The Big Bang Theory. George Lemaitre connected the pieces that not even the great Einstein would accept, that the universe wasn’t just static and was expanding. He concluded that the universe today is bigger than it was ever before and at the very beginning was very small. Edwin Hubble would see something that destroyed Einstein's theory of a static universe. Back then people just thought that the milky way was the entire universe, but they were very mistaken. The Hubble telescope revealed that the Sun is one of billions of stars that are in our universe. Edwin Hubble could see how far a star was by looking at how much light is visible. The brighter the light the closer it is to you. Hubble had found some visible dust in the milky way and did the math and it turned out to be 1,000,000 light years away. In that moment he figured out that the Andromeda galaxy was
... his announcement of his theories, Einstein applied his General Theory of Relativity to establish a model of the structure of the universe in which he believed the universe to be infinite and unchanging but this idea was not supported by relativity. In attempt to fix this issue to satisfy his theory, Einstein introduced a positive cosmological constant by which the universe could exist as a static, infinite sphere. The strengths of Einstein’s model were his idea of a curved space-time and the introduction of his General Theory of Relativity describing that time moved slower near an object the size of a planet. A major weakness of his model was that he believed the universe a static and eternal continuum which was later disproved. Technology limited the development of this model as many outcomes of his predictions could not be tested because technology was limited.
...ng of the space is biblical. Researchers are trying to prove that God sized the universe smaller than it is today. In 1996, observations of very particulars ways needed a new change. “It always shown that the universe would slow its rate of expansion,” said Vesto Slipher. This procedure causes gravity to pull, and it slows down the expanding of space. Dark energy is not understood. It’s some type of fluid, unknown to physics. In the 20th century, they made a giant leap in how humans perceive the comos. ”The universe began with a big bang is essentially conclusive and may stand as the most profound discovery in humans,” said Hubble. Particle physicists have constant theories about history of the universe. They tested their theories precisely experimentally. Theories combine general relativity and quantum mechanics. That’s the evolution of the big bang theory.
The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
The idea of cosmology has been around since the beginning of time, however, as times change, so does ideas and theories. There have been many contrasting ideas of what cosmology is and what is at the center of the universe. Many philosophers, scientists, and theorists have debated about what is at the center of the universe since 384 B.C. and now we have a better idea of the universe we live in and what is at its center. Cosmology, the study of the universe, has been constantly changing and evolving over time, requiring people to reject previously-held beliefs, challenge the status-quo, and shift their perspective.
