All living beings have the tendency of migrating on a large scale due to unfavourable climatic conditions, non availability of food, water, large scale diseases, natural calamities etc. Many a futuristic technologies are graphically, visually shown in various media including movies, serials, books, etc. Some of the technologies
and their possibilities are discussed below.
Movement on this planet alone is huge and the number of high speed vehicles is increasing every year. Be it aircrafts, trains, cars, bikes etc, everyone wants speed ie. to move the greatest distance in the shortest amounts of time. This need has arisen because of the limited life of humans and the desire to do a lot in one life. This speed makes everyone to count the seconds and thus the smaller things in life are lost. On earth the faster modes of transportation can be achieved in only air, because it provides the least amount of friction. The drag at higher speeds is all the same be it travel on land, water, underwater or air. Personalized air travel
vehicles are being developed, but the safety of the vehicles is the only problem and control of traffic is the main obstacle. The cost of the vehicles is also very high due to production of a few numbers.
In air travel, the vertical lift is the most suitable and one cartoon Jetsons depicts the personal airtravel and the air traffic control. This to happen in real life is still a number of decades away and not centuries. As the number of people travelling by air is increasing the need high reliability engines are successfully developed. The no. of people dying in aircrashes is very less compared to people dying in road accidents. But the problem with air travel is the cost and safety in mid air. Technology of catching a plane in midair and bringing to halt in midair or landing a huge jumbojets after catching is the next technology that is required. For this technology the catching plane should be very huge or a number of smaller planes have to catch one big plane. When talking about a number of smaller planes, the nano technology or microbots will be helpful in repairing the airplanes in midair in the event of a failure, but if the air crashes are to avoided then a plane catching system has to be developed.
The highspeed trains, cars, bikes are breaking new speed barriers, but the maximum speed of travel that they can achieve is limited. One technology that can achieve the speeds of planes are the trains run by magnetic levitation. This is being implemented but the cost of the project is high due to requirement of powerful Magnets at low weights. A superconductor would be ideal material to achieve the magnetic material requirements, but a superconductor is possible at 77k which is a very low temperature. A super conductor if developed that can function at 290K can revolutionize the magnetic levitation technology. Transportation on earth would be less cumbersome as the the materials float, and there will be no road friction. this advancement in material is atleast another 50years away.
Rockets with huge tanks are being currently used to travel across planets. The load carrying capacity is very poor. To travel to another planet it takes months and the life of humans have to be increased to a very large extent so that any meaningful distance in space can be traveled in search of habitable places. New kinds of fuels probably nuclear etc have to tried apart from the conventional solid,liquid for propulsion and solar for the on board energy requirements as used in satellites and space station. A other alternative is to setup many stops like bus stops in earth so that the fuel and fool can be reloaded at many a stops, but it will be cumbersome and not a feasible mode of transportation for human migration.
Teleportation is achieved in a very very small scales at the level of subatomic particles. This invention can also be due to the errors in the measuring instruments, due to heisenberg's uncertainity principle. But work is underway. It will not be possible anywhere in the next 2centuries to transport a living bacteria from one place
to another through the teleportation, because science so far has not considered the presence of soul which builds, maintains and sustains the living things. The scientific technology has to first identify the soul and if it is transported then all the material associated with it can also be transformed and it is the soul which can rebuild the body with the materials available. The soul is a pure form of energy and it gets associated with matter. For transportation, the matter has to be converted into energy and focused at another point and the soul converts the excess energy into matter again.
Wormholes are the next step to blackholes. wormholes are supposed to connect two distinct points in space. The two points in the space will form the two ends of the wormhole and if controlled the space time will curve such that the two points can be at very less distance. Thus travelling huge distances in space will be minimized by the warping of the space and time is saved. This technology is not even achieved in any level and the theories of this existence are still evolving. Unless another 1000Einsteins work together, the problem can be solved and so even in the far visible future this technology seems to be not possible.
Tranportation is the one big problem and to avoid movement many allied technologies are being developed, but will they be enough?
