Teleportation

             Ever since the invention of wheel more than 5000 years ago, human desire to reach a place faster has lead to numerous inventions. From chariot to bicycle to automobile to airplane and rocket, all have been created with a single motive to travel faster. But all these inventions share the same flaw; it requires us to travel the physical distance. With development in the field of paranormal physics, scientists have been trying to combine the properties of telecommunication and transportation to achieve “teleportation”.
         Teleportation involves transfer of matter from one place to another without physical traversing the space between them. It deals with dematerializing an object at one point, sending the details of the precise atomic configuration at another location where it will be reconstructed. With the tremendous potential being embedded on this invention it would explore the possibilities of travelling without physically crossing the space. The idea of teleportation moved out of the realm of science fiction into the world of theoretical possibility in 1933. Physicist Charles Bennett with a team of researchers at IBM confirmed that quantum teleportation is possible, but only if the object being transported was destroyed. Since then, experiments using photons has proven that quantum teleportation is in fact possible.
          In 1998, physicists at Caltech successfully teleported a photon by reading its exact atomic structure, sending the information across 1 meter of coaxial cable and creating a replica of photon.  As predicted, the original photon was destroyed once the replica was made. In the event of teleporting objects larger than photon the main hurdle in the path is “Heisenberg Uncertainty Principle”. The principle states that determining the momentum and location of a particle simultaneously is not possible. If you cannot determine the location of a particle then how can you teleport it? The photon experiment was carried out by using a phenomenon called entanglementFor a person to be transported, a machine would have to be built that can pinpoint and analyze all of the  atoms that make up the human body. That's more than a trillion trillion atoms. The machine would then have to send this information to another location, where the person's body would be reconstructed with exact precision. Molecules couldn't be even a millimeter out of place, lest the person arrive with some severe neurological or physiological defect. The laws of physics may even make it impossible to create a transporter that enables a person to be sent instantaneously to another location, which would require travel at the speed of light. The availability of this technology tough looks bleak in the near future.
           But like all technologies, scientists are sure to continue to improve upon the ideas of teleportation to the point that we may one day be able to avoid such harsh methods. One day, one of your descendants could finish up a work day at a space office above some far away planet in a galaxy many light years from Earth, tell his or her wristwatch that it's time to beam home for dinner on planet X below and sit down at the dinner table as soon as the words leave his mouth.

What is Matter?

Definition of Matter
     Matter, generally defined as anything that has mass and occupies space is classified to exist in four of the known states viz. solid, liquid, gas and plasma. Matter has been proved to exhibit wave nature as well as particle nature. With the development of the 'String Theory', the definition of matter has witnessed a drastic change for now the fundamental particles were not atoms or molecules, not even proton, electron and neutron. Now the fundamental particle in nature was defined to be a string. A question that arises in mind is that how is matter related to fundamental particle? The answer follows by the relation that anything and everything in the world is a singular or a combination set of the fundamental particle(s). Lately the matter is defined as the different modes of vibrations of the fundamental particle, string (based on String Theory). Defining precisely matter consists of particles that are themselves different modes of vibration of the fundamental particle - string.

Superstring Theory: The Excitement

        With the change in physics we are witnessing the better understanding of space, time and origin of the universe. The atoms were earlier considered to be the fundamental particles of the universe but with this theory in place, strings were placed as the fundamental particles of the universe. The birth of string theory has revolutionized the world of physics. Some people claim it to be the final theory - Theory of Everything (TOE). It is interesting to know that the whole of  information about the universe which has been collected over thousands of years can now be derived from this single theory as expected by the supporting physicists. German physicists have compiled the whole of physics in an encyclopedia. This new theory has been compared to the transition of man from real to complex numbers in mathematics. The theory with its elegant mathematics and beauty provides answer to many of the baffling questions which were not answered by the previous theories such as the existence of diversity of substances and billions of combinations. Only time will prove its accuracy, but for now we have a new theory with promising features.
