Micheal Faraday's “Force Fields”

The concept of force fields originates from the work of the great nineteenth-century British scientist Micheal Faraday. Faraday was born to working-class parents (his father was a blacksmith) and eked out a meager existence as an apprentice bookbinder in the early 1800s. The young Faraday was fascinated by the enormous breakthroughs in uncovering the mysterious properties of two new forces: electricity and magnetism. Faraday devoured all he could concerning these topics and attended lectures by Professor Humphrey Davy of the Royal Institution in London. One day Professor Dave severely damaged his eyes in a chemical accident and hired Faraday to be his secretary. After Davy died in 1829 Faraday was free to make a series of stunning breakthroughs that led to the creation of generators that would energize entire cities and change the course of World Civilization. The key to Faraday’s greatest discoveries was his “Force Fields”. If one places one places iron filings over a magnet, one finds that the iron filings create a spiderweb-like pattern that fills up all of space. These are Faraday’s lines of Forces, in the Near future cars will be floating on a magnet using Levitation Technology.

Time Travel[edit]

“Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, either sending objects (or in some cases just information) backwards in time to some moment before the present, or sending objects forward from the present to the future without the need to experience the intervening period (at least not at the normal rate).”

Time Travel in Two Directions:

“Some theories, most notably special and general relativity, suggest that suitable geometries of space-time, or specific types of motion in space, might allow time travel into the past and future if these geometries or motions are possible. In technical papers, physicists generally avoid the commonplace language of ‘moving’ or ‘traveling’ through time ('movement' normally refers only to a change in spatial position as the time coordinate is varied), and instead discuss the possibility of closed time-like curves, which are world-lines that form closed loops in space-time, allowing objects to return to their own past. There are known to be solutions to the equations of general relativity that describe space-times which contain closed time-like curves (such as Gödel space-time), but the physical plausibility of these solutions is uncertain.”

Time Travel to the Past:

“The theory of general relativity does suggest scientific grounds for thinking backwards time travel could be possible in certain unusual scenarios, although arguments from semi-classical gravity suggest that when quantum effects are incorporated into general relativity, these loopholes may be closed.”

Time Travel to the Future:

Special and General Relativity state that time passes more slowly as you approach the speed of light. So if one twin were to travel a very far distance at a very high speed, he would age more slowly relative to his twin on Earth. When he returned home thousands of years in the future, he would have aged very little, while his twin would have grown very, very old. So in this sense, time travel is theoretically possible. — Preceding unsigned comment added by Marwan H. Al-Raisi (talk • contribs) 20:25, 27 July 2013 (UTC)[reply]
