1. All laws of physics are valid in all inertial frame of references. 2. Light travels through space at a speed of c = 3.00 × 10 8 m/s, relative to all inertial frames of reference.

 Simultaneity is not an absolute concept  Two events that are simultaneous in one frame of reference are not simultaneous in another frame of reference; that is in motion with respect to the first

 Objects cannot have a speed equal to or greater than the speed of light

1. The Star Wars spacecraft Tie Fighter flies at a speed of 0.8c with respect to the Earth. Luke Skywalker determines the time interval between the two events on Earth is 20h. What is the time interval for Tie Fighter? a) 16.7h b) 20h c) 30h d) 33.3h

2. It is the year A rocket passes by at a speed of 0.3c. The length of the rocket is 100m. What is the length at rest? a) 108.4m b) 104.8m c) 108m d) 104m

 Superstring theory is the favoured version of string theory  Fundamental entities in the universe are microscopic, multi- dimensional strings  Strings are made of 10 or more dimensions, but only 3 are seen

 Einstein’s general relativity theory incorporated in Kaluza’s geometrical representation of electromagnetic field results in a five-dimensional universe  Strings are assumed to obey Einstein’s equations in space- time resulting in a possibility to combine quantum mechanics with general relativity  Gravity remains as the only force that can be associated with space-time

 Einstein’s theory of special relativity revises conceptions of time, length and energy allowing us to analyze the effects of motion at high speeds  Einstein’s equation of total relativistic energy makes it possible to predict the amount of energy available from processes resulting in a decrease of mass  e.g. Energy available from the complete conversion of coal
