Short Definition:
Time Dilation is a phenomenon observable through the change of measuring of
elapsed time by two clocks. The change usually occurs due to the difference in
velocity or gravitational potential. The faster you move relative to some object,
the slower time seems to flow.
Detailed Definition:
Time Dilation is an occurrence which takes place due to the difference in velocity
or gravitational potential of a given object. It occurs when one of the objects has
higher velocity than the other (commonly called a reference frame). The reference
frame is a coordinate system defined by certain characteristic points, this frame
is stable while the other object travels with a certain velocity, different from the
frame. What can be then observed is that the travelling object experiences time
slower, than the reference frame (observer). This phenomenon is strictly
connected to Einstein's theory of relativity, as the time passes differently, relative
to the state (either gravitational or velocity) of the object. Time dilation has been
observed and calculated on the International Space Station. The differences in time
perception are virtually insignificant (in milliseconds) at small distances, but
might increase to even years in difference.
Etymology:
Time, from Old English "tima" defined as limited space of time. Dilation from Late
Latin "dilatationem" meaning widening of something.
Sample Sentence(s)
1. The astronauts on the ISS experienced time dilation of around 20 milliseconds,
compared to earth.
2. The time on ISS is lagging by about 0.01 seconds for every 12 months on earth,
due to time dilation.
