Nice topic DS. I would like to put some comments.
=====================================================================
<center>TIME</center>
=====================================================================
Time is of many types
1- Solar time
We are all familiar with this time. Sun has been the source of time measurement from centuries (maybe it gave berth to the concept of time).
This kind of time depends upon the motion of sun.
2- Sidereal time
It is a long topic and this time has many purposes. Important things are;
This time is based on far-away fixed stars and its one day is four minutes shorter then solar day.
3- Dynamical time
It is based on the annual revolution of earth around the sun.
4- Atomic time
Time produced by atomic clock, most accurate clock on earth.
5- Biological time
Time produced from the clock that God has put in all living creaturesâ mind. This clock takes data from physical changes in environment i.e. Day and night, Seasons etc.
=====================================================================
It is not impossible that time could be changed. Below is given an experiment, considering it if we run a craft at a speed of earthâs rotation, time can either be stopped or doubled, depending upon the direction.
Time is not a physical constant. It is created from and affected by motion and gravity. It is said that near large mass objects or in high gravity, time slows down or even stops (Black holes are example). It is called time dilation.
Time dilation effects due to motion were experimentally observed in the early 1970s. Researchers placed atomic clocks on commercial airliners and observed the expected changes in time as measured by those clocks relative to similar clocks on the ground. In particular, when the planes traveled east, in the direction of Earthâs rotation, the clocks on the airliners were 59 nanoseconds (59 billionths of a second) slow relative to the atomic clocks on the ground. When the airplanes traveled west, the clocks were 273 nanoseconds fast. This discrepancy is caused by the rotation of Earth, which causes an additional time dilation. If the effect of Earth's rotation is removed, the time dilation produced by the motion of the airliners confirms Einstein's theory of how time changes with motion, as the dilation is in agreement with predictions made by the theory.
=====================================================================
Can we go to the past or future
I think no (in the light of current theories)
We have observed that if we make time run slow, it will cause slow changes in our body and other environment and if we make it run fast we'll get older soon. It means that if we make time reverce, we'll be children again and then distroyed and if we make it run fast, we'll be old and dead. So there is no possibility of going into past or future before any further developments.
It can only happen when we use two different time threads. One for us (Stoped) and one for ouside world (Fast/Slow/Reverse).
