| Quantum Physics is the branch of physics that uses quantum theory to describe and predict the properties of a sub-atomic physical system. |
| Quantum Theory is based on the principle that matter and energy have the properties of both particles and waves, created to explain the radiation of energy from a blackbody, the photoelectric effect, and the Bohr theory, and now used to account for a wide range of physical phenomena, including the existence of discrete packets of energy and matter, the uncertainty principle, and the exclusion principle. |

| Heisenberg's uncertainty principle says that it is impossible to discern concurrently and with high accuracy both the position and the momentum of a particle (as an electron.) By the time your senses have noticed an object, it may have moved to a diferent location. The process of discerning an object's position and buildup alters these qualities of the object. When you see a particle through a ultramagnified microscope, the microscope uses photons to create a series of data that is then transformed inot an image by a computer. However, by sending photons directly towards the particle you wish to see, you alter either the velocity or position of the particle. |

| Teleportation |
| Although you may be surprised by this, we have many types of teleportation today. However, we do not teleport materials and it is not the same as in Star Trek. The telephone teleports sound waves as electricity. The internet transfers information. Fax machines teleport images. If we can record the details of any matter why can't we recreate it at a different location? It is theoretically possible to copy a human, but according to the visible human project by the American National Institute of Health,10 gigabytes are required to fully present three dimensional details of of a human down to one milimeter resolution in each direction. Heisenberg's Uncertainty Principle (above) makes this appear impossible. However quantum theory says that the precision with which we can measure position and velocity of any particle are limited by a formula which makes it possible. |
| Multiple Universe Theories |
| Theory One |
| When an organism thinks of a universe, it is actually created. All the stories you know are real in other universes. If you had the technology, you could have tea with the mad hatter, or even go to school at Hogwarts. If you were able to travel between universes, you could visit your dreamworld. This other universe would have a different set of laws from our own and many different possibilities. In this newly created universe, organisms would imagine other universes and these too would be constructed, creating an infinite amount of universes. This presents an interesting thought: We, everything in our universe, are fictional. We are merely figments of imagination in the mind of someone living in another universe. There is a possibility we are not fictional, but the chances are slim. Only one universe out of all, an infinite amount, is real. Only that one is non-fictional. |

| Schrodinger's equation is an equation that describes the wave nature of elementary particles and is fundamental to the description of the properties of all matter. |
| The Schrodinger equation gives the kinetic energy plus the potential (a sum also known as the Hamiltonian H) of the wave function psi, which contains all the dynamical information about a system. Psi is a scalar function with complex values. For the time-independent case, energy is written at the operator -i hbar d/dt, and kinetic energy as the square of the momentum operator, i hbar Del, over 2m. Given the potential V(0, X) and suitable boundary conditions, solving this differential equation generates a wave function psi which contains all the properties of the system. |

| Before the complicated field of quantum physics, Newtonian (classic) physics alone governed the movement of mass. Newtonian laws are much simpler and are taught at a more basic level. For example, it is a known fact that electrons orbit the nucleus in any given atom - much like planets orbit the sun. According to classical physics, however, the electron should spiral into the nucleus in less than a second. Obviously, this does not happen therefore, the laws of classical physics are very flawed. Subjects such as Chemistry solely depend on the interactions between electrons in an atom, and if you ask any chemist, all life depends on chemistry. The old phsics system would not permit such sciences to exist. Scientists were baffled by these loopholes in the law, so they created a new set of rules, theories, and equations for smaller interactions to pick up where Isaac Newton and other classical scientists left off. |

| The Practical Effects of Time Travel |
| As you have already read, there may be ways to accelerate and decelerate the speed of time. There are many inexplicable effects that may come of this practice. Here is an example of such consequences. Put yourself into a chess player's mind. You wish to thwart your opponent's strategy and traveling into the future is your means of discovering it. So you travel into the future and your opponent's strategy is revealed. You return to the orginal time position and make your move. Now your opponent changes his strategy. Is this a result of your travels or is there an certain inaccuracy in your findings? James Glieck raises an interesting question in his theory of chaos. Can one alteration of time lead to another? The same may happen on a larger scale. If everyone could had the convenience of time travel, there would be no existence of more than one person at any given time. There would be an infinite amount of places to travel in time, because the road of time itself is infinite. The course of chaos Glieck describes would take action because there would be numerous existences that would eventually coincide, so that you might meet your grandmother before she was married. |
| Is there a theory which would describe all the forces and particles that exist in the universe at any point in time? This is the current debate responsible for the direction in which science progresses. Time travel seems improbable due to the many paradoxes, but might there be something which prevents paradoxes from occuring and is what you do in an alien time part of history, not changing it? The reason for its doubt by physicists is that it cannot yet provide an understanding of the reality behind observable events. |

| Quantum Physics |
| Isaac Newton, in 1672, proposed that light was corpuscular, made up of multiple minute packets of light. But, in 1803, the majority of the world was convinced by Young's double slit experiment, that light was composed of waves. Max Planck, in 1900, decided that he would revive the wave-particle debate by again suggesting that light was made of particles. Though Planck was laughed out of his lab, one prominent physicist seriously considered it. Albert Einstein showed the corpuscular nature of light with his experiments on what came to be known as the photoelectric effect after he thought about Planck's idea. When the electron was discovered in 1897, it was considered to be a particle. However, de Broglie in 1924 said that the wave character of the electron was observed. Were photons and electrons waves or particles? The one helpful property of these observations was that both photons, electrons, and all sub atomic particles, acted similarly. Quantum theory is modeled by their behavior. |
| There is an infinite amount of universes. For every possibility there is a universe in which that possibility transpires. In that universe, there may be a different concept of what is rational or obvious. If you push a button on your computer, there is an infinite amount of positions in which your finger may have landed. It may have landed a nanometer to the right of a certain position or half of that, or half of that, etc, creating an infinite amount of possibilities A.K.A. an infinite amount of universes. |
| Theory Two |
| At first, quantum entanglement may seem like some radical idea from a science fiction book, yet it is one of the most common occurrences sub-atomic world. Random particles, with neither provocation nor reason, switch places with each other. No matter how far apart or how close together, this odd incidence takes place. Presently, there is no explanation for why this happens, and perhaps there never will be. However, quantum entanglement is precisely why teleportation, and even time travel is possible. All it would take to transport a body of matter from one place to another would be great timing, so that the billions of particles that make up a book, for example, would all switch places with other particles at the same exact moment. Now, a book would be where seemingly meaningless particles were before. And if you believe in the multiple universe theory (which not everyone does), then why could particles from different universes in which there was a different time not switch with particles from the present time? If this sounds a little over the top, there is another possibility of teleportation. There is a type of teleportation that goes on every day. Fax machines transport electrons that have either an up (1) or down (0) spin. The electrons almost instantaneously arrive at the receiving fax machine, and are rearranged and deciphered into a replica of the document was at the sender's fax machine a few seconds before. This could be done with information on a greater scale. What would have do be done is that more information would have to be sent with each electron. Maybe sequence of the electrons could indicate 2, 3, 4, or even 5. However, transporting a human this way would require so much energy and computer power that it would be impractical, although if technology keeps its remarkable pace, we may be transporting our groceries to our computer before we know it. |
