Time Dilation and the theory of Relativity
Time Dilation
•According to the
detailed theory of Relativity time dilation is the difference in elapsed
time{the amount of time from the beginning of an event to its end}measured by
two observers. Time dilation
explains why two working clocks will report different times after different
accelerations. For example, at the ISS time
goes slower, lagging 0.007 seconds behind for every six months. For GPS
satellites to work, they must
adjust for similar bending of spacetime{in physics, spacetime is
any mathematical model that
fuses the three dimensions
of space and the
one dimension of time into
a single four-dimensional continuum. Spacetime diagrams can
be used to visualize relativistic effects
such as why different observers perceive where and when events
occur.} to
coordinate with systems on Earth
The theory of Relativity holds within
mainly two theories – Special Relativity and General Relativity. Special
relativity-special relativity applies to the elementary particles {in particle physics,
an elementary particle or fundamental
particle is a subatomic
particle with no substructure, thus not composed of other particles}and their interactions, describing all
the physical phenomenon except gravity. General Relativity explains the law of
gravitation and its relation to other forces of nature.it explains that the
Earth resides on a blanket of the universe and that the universe exerts
pressure on every object on Earth causing Gravity.
