<strong>ETERNITY</strong> <strong>HAS</strong> <strong>ALREADY</strong> <strong>BEGUN</strong><br />

the person who put you in there says that you spent only two days<br />

in there; that the sun you saw from the window was falsely produced;<br />

and that the clock in the room was especially regulated to<br />

move faster, then your calculation would be erroneous.<br />

This example dramatizes that the information we have about the<br />

rate of time's passing is based only on references that change according<br />

to the perceiver.<br />

In the same way, the way that the speed of the passage of time is<br />

perceived differently be everyone depending on the circumstances<br />

proves that time consists of a psychological perception. For example,<br />

a 10-minute delay while waiting to meet a friend may seem a<br />

very long time to you. Or an extra 10 minutes sleep may seem very<br />

long to someone waking to go to school or work after a sleepless<br />

night, and he may actually imagine he has had a full night's sleep<br />

because of it. Under some circumstances, the opposite may apply.<br />

As you will remember from your student days, a 10-minute break<br />

after a lesson lasting 40 minutes, or seeming to last a century, may<br />

go by very quickly.<br />

That relativity of time is a scientific fact, also proven by scientific<br />

methodology. Einstein's Theory of General Relativity shows<br />

that the speed of time changes depending on the speed of the object<br />

and its distance from the center of gravity. As speed increases, time<br />

is shortened—compressed—and slows down until it approaches to<br />

the point of stopping entirely.<br />

Einstein himself gave an example. Imagine two twins, one of whom<br />

remains on Earth while the other goes into space at a speed close to the<br />

speed of light. On his return, the traveler will find that his brother has<br />

grown much older than he has. The reason is that time flows much<br />

more slowly for the person who travels at near-light speed. The same<br />

example may be used for a father travelling into space on a rocket at<br />

99% of the speed of light, and his son who remains on Earth.
