Like the boundaries on earth, mankind has always looked to the sky in awe for it seemed boundless in its ever growing horizon. Out of all the cosmos that’s being found and discovered every day, there is one object that stands to elude scientists still, the black hole. Albert Einstein, and all the brilliant scientists after his, help to design and create a part of the universe that’s very crucial to understanding existence. The perimeters of a black hole have been a great this that has been discussed
Most people have heard of antimatter before but don’t know what it is or means. Antimatter is used in particle physics and consists of antiparticles. These antiparticles have the same mass as regular particles but they have an opposite charge from other particles as well as other differences in particle properties. Antimatter can be created in particle accelerators and also can be produced naturally. It is created naturally when radioactive isotopes decay. When antimatter is created it could potentially
The International Space Station is not the first habitable artificial satellite but it by far surpasses any attempts in the past to create a unified structure in space that can be used for a multitude of different purposes. It was such an immense project, when first introduced in 1988, that there was no way that one agency could fund the entire planning and construction. Because of this fact, three agencies merged, each adding their own piece to the final construction of the ISS. The United States
If you casually mention the name Stephen Hawking in conversation, you are likely to get a number of reactions from people.Some people know him from cameo appearances in movies or TV shows like The Big Bang Theory. Others have leafed through his popular book, A Brief History of Time. People recognize him as an outspoken representative for the disabled, and a leader of the scientific community.But how many people know him for his research? Professor Hawking has certainly lived an impressive life, and
Have you ever watched a sci-fi movie and wondered if some of the subjects on futuristic transport occurring in space could be a possibility? For many years scientists have been discovering new phenomenons in space. In 1916, the first black hole was discovered by Karl Schwarzschild, which wasn't proven until the late 1950’s. A wormhole is a hypothetical connection that you can travel through to get from point A to point B almost instantaneously. Have you ever wondered what might lie on the other
neutrinos and were created along with their antiparticles. There are minuscule amounts of protons and neutrons at this stage; approximately 1 for every one billion photons, neutrinos or electrons (Maffei). The density of the Universe in its first moment of life is thought to have been 1094g/cm3 with the majority of this being radiation. For each billion pairs of these heavy particles (hardens) that were created, one was spared annihilation due to particle-antiparticle collisions. The remaining particles
Quark: Quarks are groups of elementary particles which are the basic components of all hadrons. Quarks have some properties, like electric charge, mass, color charge and spin. There are flavors of quarks which are up quarks, down quarks, charm quarks, top quarks, strange quarks and bottom quarks. These different kinds of quarks make up protons, neutrons and baryons. And quarks also comprise mesons. Among those different kinds of quarks, up quarks and down quarks are the most common ones. Most importantly
Black holes are one of the many amazing unexplainable wonders around the world. Black holes are also very abundant in many galaxies especially the Milky Way. There is believed to be at least over ten million black holes scattered around the Milky Way galaxy alone. In every galaxy there is a supermassive black hole that is at least billions of times as big as the sun and it is big enough to swallow the whole solar system. The first black hole was discovered in 1971 and John Wheeler, an American astronomer
Yui Yee Chow Mr. Andrew Curtis IB Theory of Knowledge 9 Feb 2018 “Suspension of disbelief” is an essential feature of theatre. Is it essential in other areas of knowledge? Develop your answer with reference to two areas of knowledge. “Suspension of disbelief” is an essential feature of theatrical transactions where the audience accepts the premises of the story as a false reality, but pretend to not know it in order to empathise with the actors. “Suspension of disbelief” in areas of knowledge other
introduction A quantum computer is one which exploits quantum-mechanical interactions in order to function; this behavior, found in nature, possesses incredible potential to manipulate data in ways unattainable by machines today. The harnessing and organization of this power, however, poses no small difficulty to those who quest after it. Subsequently, the concept of quantum computing, birthed in the early 80's by physicist Richard Feynman, has existed largely in the realm of theory. Miraculous
Stephen W. Hawking Stephen W. Hawking has a mind set that is beyond today's general way thinking. His attempts to identify a grand unification theory that unites everything we know about the physical world and science far exceeds any realm of thinking that has ever graced this earth. Hawking was born on January 8, 1942 in Oxford, England. He spent most of his childhood in and around London, and was always a bit of a self-educator. He was interested in the stars, and his family used to lie out on
A Journey to the centre of a Black Hole! The Universe can be an unbelievably violent and extreme place. Nowhere is this seen more clearly than with the many exotic objects that can be found scattered throughout the Cosmos – from transient stellar explosions to all consuming Black Holes. What is a Black Hole? A Black Hole is a compact/ localised region of space surrounding a collapsed mass within which gravity is so powerful that neither matter nor radiation can escape – in other words, the escape
Stephen Hawking has been hailed as one of the most brilliant theoretical physicists since Albert Einstein. Hawking was born on January 8, 1942, which as he likes to point out is the 300th anniversary of Galileo's death. Hawking originally studied at Oxford University in England studying physics even though he would have preferred math. He moved onto Cambridge University to work on his PhD in cosmology. Hawking's career has focused upon the cosmic entities known as black holes, and has extended
Black Holes The American scientist John Wheeler coined the phrase “black hole” in 1969 to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die. Gravity causes the center to contract to higher and higher temperatures, while the outer regions swell up, and the star becomes a red giant. The star then evolves into a white dwarf, where most of its matter is compressed into
Those wishing to preserve the possibility of time travel must discard any hope of traveling to the past, which we will henceforth refer to as “past-travel,” due to the paradoxical problems involved in the journey. Of the many paradoxes that plague theories of past-travel, the double occupation paradox proves most severe, not only due to its underlying physics violations, but also the fact that those who argue against the paradox have failed to acknowledge its severity. The paradox holds that a time
Introduction Quantum mechanics or also known as quantum physics is a field of science which studies the behaviour of particles at sub-atomic level. This theory tells us that short-lived pairs of particles and their antiparticles are constantly being created and destroyed in an apparently empty space. In quantum mechanics the weird behaviour of electrons are not accurately explained and until now not a single theory is acceptable by the whole scientific community to postulate the phenomena. The
Cosmic rays are to scientists much like photons are to astronomers. Just as astronomers use light (or photons) to view our galaxy and beyond, scientists use cosmic rays to infer useful properties about our galaxy. In fact, cosmic rays offer one of the few ways in which scientists can actually sample real matter outside of our solar system. By identifying the various nuclei that are dispersed throughout our Galaxy, scientists hope to unravel the mechanisms that actually produce these nuclei -- from
Black Holes Every day we look out upon the night sky, wondering and dreaming of what lies beyond our planet. The universe that we live in is so diverse and unique, and it interests us to learn about all the variance that lies beyond our grasp. Within this marvel of wonders, our universe holds a mystery that is very difficult to understand because of the complications that arise when trying to examine and explore the principles of space. That mystery happens to be that of the ever elusive, black
The Origin of the Universe Since the dawn of intelligent man, humanity has speculated about the origins of the universe. There is evidence, which indicates that the universe started around 15 billion years ago. This is probably the greatest discovery imaginable; however, the universe still seems to be a very controversial subject. Most scientists agree that there was a beginning but there is a lot of speculation of how it (the universe) actually started. The much-celebrated Greek philosopher
