thanks brother for the site.
this is what i can copy paste:
In his
special theory of relativity, Einstein showed that time and length are not as absolute as everyday experience would suggest: Moving clocks run
SLOWER and moving objects are shorter. Those are just two of the unusual properties of Einstein's world! Another consequence of special relativity is the most famous formula of all: E=mc², stating that two physical quantities which physicists had defined separately, namely energy and mass, are in fact equivalent.
In Einstein's
general theory of relativity, space and time become even more flexible. "Your mileage may vary," and so may the time intervals you measure, depending on
WHERE AND WHEN you are. This flexibility has an analogue in the geometry of surfaces like that of a sphere - there is a
curvature of space and time. Distorted space and time influence the way that material objects or light move. In fact, there is a direct connection to the cosmic interaction that holds the universe together, makes the earth orbit the sun and keeps our feet on the ground: gravity.
One of the most surprising features of special relativity is that a number of statements and results which we usually think to be absolute turn out to be
observer-dependent. In particular, statements about space and time, distances and duration turn out to be relative.
For example, in Einstein's theory, simultaneity is a relative concept. Imagine that there are two events which an observer in space station A judges to be simultaneous - say, the explosion of a firecracker at one point in space and an alarm clock going off a few miles away. For an observer in space station B, which is moving relative to A, this statement will not necessarily be true: In general, such an observer will come to the conclusion that one of the events happened earlier than the other.
i think this theory explain why it is 1 day in heaven equal with 1000 years on earth
