The whole idea of time and black holes has been questioning scientist and many common people for decades. Whether or not the theories provided make it physically possible to allow us to ever use any type of a black hole to an advantage? Technology over these past years has allowed us to learn more and more about what black holes are and what they can do. While also allowing ourselves to discover new possibilities that they might bring forth to greater innovations in our near future. But we can only imagine, through our knowledge and technology, what a black hole could do for us, due to all the dangers they bring forth. A black hole is what’s left after a star has collapsed and died of old age, its gravitational force was so strong, the star could no longer withstand. This makes the dead star exert very strong forces of gravity, making escape once entering the event horizon of a black hole impossible. This event horizon is most commonly simplified as, “the point of no return,” because it’s most likely impossible for anything to escape its horrendous force. Somebody that whiteness’s this would seem as if the object that entered the event horizon will become slower and slower as if it will never pass through. The object will become redshiftted as time passes, no light is emitted from the hole to someone witnessing, but to whatever is passing through then it will pass as if time remains normal. Some do believe that black holes will eventually die by evaporating, it will leave behind lots of radiation. Physically using a black hole for our advantage, saying that if it were ever possible, then it could be something that would change our everyday lives. Discovering this potential will be our greatest defyi... ... middle of paper ... ...eality. Our knowledge will only allow us to go so far, but we have accomplished so much in the discovery of time and space. Technology will soon advance as to where these theories could be proven and physically be possible. Black holes are thought to be a portal to another dimension or a way for time to slip. Mainly all these theories follow the laws of physics and do not cross any illogical possibilities. For a way in which we can achieve any of these would be through many more years of research. If even physically possible for any of these hypotheses to coexist with one another. Learning that there’s a possible way for black holes to allow time to lapse or elapse. The study has been a challenge, finding ways in which these ideas could work. Theories about space time are not always true, but they allow us to have an improved understanding towards the, what ifs.
Death by Black Hole: And Other Cosmic Quandaries is a biography that is divided into 5 chapters total and a total of 42 mini sections. Bringing together more than forty of Tyson's favorite essays explores a myriad of cosmic topics, from what it would be like to be inside a black hole to the movie industry's feeble
The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
The particles escapes as Hawking Radiation. On the other hand, the anti particle gets sucked into the black hole. Since the anti particle has a negative mass, it actually decreases the mass of the black hole. The effects of Hawking radiation are generally negated by the fact that black hole sucks more in than it radiates (SST). But eventually it will not have anything more to suck in and start to lose mass.
For the Science Reader project, I read Black Holes, Wormholes, and Time Machines by Jim Al-Khalili. Interested in time travel and the secrets of space, I chose this book with hopes of better understanding our universe.
At a glance, the concept of time travel seems absurd. Yet given some thought, you realise the metaphorical wall between the past, present, and future is smaller than you think. Light travels at a constant velocity of about 300,000 km/s. It is common knowledge that nothing can travel faster than that speed (as I will prove later on) and therefore because your eyes are sensitive to visible light – everything you see is a light wave in some form. Because of this finite velocity of light, if we observe a star, say Alpha Centauri 4 – which is 4 light years away – we do not see it as it looks today, but as it looked 4 years ago! If you look at the Andromeda Galaxy – 2 million light years away – you see it as it appeared 2 million years ago. Just as when you look at yourself in a mirror – 1.5 metres away – the image you see of yourself is not you now, but you 10 nanoseconds ago (0.00000001s)2. In other words, you look into the past every moment of your life.
...ke for instance the two images below. The first is a two-dimensional representation of the gravity of a normal star. Imagine any object floating through space as a marble. Said marble rolling along the flat surface of the space will roll into the indentation made by the sun's gravity. If you flick the marble hard enough, it can roll out of the indentation and roll away. The second pic is a representation of the gravity made by a black hole. Notice that if the marble rolls into the hole, there's no way it can get out, since there is no end to the hole.
A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.
As I said before, gravity is the key for a black hole’s immense power. The black
Although Dr. Hawking impacts many areas of science and cosmology, his work with black holes has revolutionized modern physics. He works in all areas of black holes, including how they work, singularities, and most importantly, Hawking radiation. Black holes are very simpl...
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 side of a black hole? Some scientists have been studying the “holes of space” and have found very surprising results: The black hole, the white hole, and the wormhole. In this paper we will explore wormholes and discuss how black holes and white holes relate.
Just recently a major discovery was found with the help of a device known as The Hubble Telescope. This telescope has just recently found what many astronomers believe to be a black hole, After being focuses on a star orbiting empty space. Several pictures of various radiation fluctuations and other diverse types of readings that could be read from that area which the black hole is suspected to be in.
There are also highly exotic ideas, which lie on the tantalizing fringes of modern theoretical physics. If the universe is a multidimensional place with human beings only able to perceive three dimensions, perhaps a way can be found to shortcut through the 'higher' dimensions. These so-called wormholes are currently having their mathematics calculated by the theorists but if they can be utilized for travel then perhaps the entire universe will become accessible to us. Traveling to different planets may take no more time than traveling to different countries does now!
Throughout the ages, outstanding physicists, to the movies, to some of the greatest science fiction novels of all time, have pondered the idea of time-travel. The thought of actually being able to travel to another time or universe has long since enthralled, enveloped, and overwhelmed some of the greatest minds in the history of physics. No one person can actually prove any of their theories, but a few actually make sense. Meaning that they do not violate the laws of physics. One of the main theories suggested, are wormholes. Wormholes are considered to connect two regions of flat space-time, two universes, or two parts of the same universe. There is a lot of theoretical evidence that wormholes exist, with an equal amount of evidence that they do not exist. However, no matter what one’s belief is, the existence of wormholes still makes you wonder…
Black holes are the result of the death of a massive star, leaving behind a dense remnant core that eventually collapses to create a gravitational force so strong that nothing, including light, can escape the force. The theory that black holes existed started back in the early 1900s and since then astronomers and scientists have been trying to get a better understanding of them. This phenomenon has been a working progress for astronomers and scientists for many years and as we develop a better understanding of our solar system, the more likely it is to make a significant discovery that can answer some of the most difficult questions about our incredible galaxy and solar system. The more information we are able to acquire about our universe, the more questions we might be able to answer about our existence. With advancements in technology we may be able to see some significant discoveries and insights into the world of black holes.
...t is that human reasoning abilities have allowed mankind to develop a virtual telescope far beyond the reach of our newest space viewing technologies. With this theory, humans come closer to realizing our place within the multiverse and the uniqueness of our own universe. The conflicting ideas, though difficult to prove one way or another, provide an impetus that will stimulate further research into this field, opening new doors and potentially useful technologies that could further humans’ understanding of everything on which our knowledge rests.
