The Rise of Special Relativity
2007-10-21 23:54:00 In 1905, Einstein?s Theory of Special Relativity was proposed. The reason that it is so “special” is because it was part of the more complex and extensive Theory of General Relativity, which was published in 1915. His theory reshaped the world of physics when it contradicted all previous laws of motion erected by Galileo and ... More About: Rise

A Theory on Time And Space
2007-10-19 13:55:00 worth a read..: Though there are many analogies between time and space, there appear to be three commonplace yet deeply perplexing features of time that reveal it to be quite unlike space. These can be called ?orientation?, ?flow? and ?presence?. By orientation I mean that there is a direction to time, a temporal order between events ... More About: Space , Time , Theory , Theo

Why Time May Not Exist
2007-10-18 19:35:00 by Tim Folger No one keeps track of time better than Ferenc Krausz. In his lab at the Max Planck Institute of Quantum Optics in Garching, Germany, he has clocked the shortest time intervals ever observed. Krausz uses ultraviolet laser pulses to track the absurdly brief quantum leaps of electrons within atoms. The events ... More About: Time , Science News , Exist
