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.
Slide 3
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 3000. A rocket passes by at a speed of 0.3c.
The length of the rocket is 100m. What is the length at rest? a)

Slide 21
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
Slide 22
Einsteins general relativity theory incorporated in Kaluzas
geometrical representation of electromagnetic field results in a
five-dimensional universe Strings are assumed to obey Einsteins
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
Slide 23
Einsteins theory of special relativity revises conceptions of
time, length and energy allowing us to analyze the effects of
motion at high speeds Einsteins 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
