Through a telescope, the One of two twins sets off into
twin on Earth sees that space at a speed approaching
the other twin appears that of light, while the other
younger than himself. twin remains on Earth.

The twin who left
in a rocket returns
to Earth. The twin
who had remained
behind has aged,
while his astronaut
brother is much
younger.

According to Einstein’s twin paradox, one twin remains on Earth while the other
sets off into space at a speed near that of light. When the one who traveled into
space returns to Earth, he will find his brother to be older than him. The explanation
is that time passes slower for the twin traveling in space at a high rate of speed.

According to Einstein’s gen er al the o ry of rel a tiv i ty, the speed of time chan ges ac cord ing to the ve -

loc i ty of a body and its dis tance from the cen ter of grav i ty. As ve loc i ty ris es, time con tracts and is com -
pressed, in such a way as to run slow er and even tu al ly ap proach the point of stop ping al to geth er.
To use an ex am ple cit ed by Einstein, one of a pair of twins re mains on Earth while the oth er heads
out in to out er space at a speed near that of light. When the trav el ing twin re turns to Earth, he will find

him self much young er than his broth er. The rea son is that time flows more slow ly for the broth er trav -
el ing at a high ve loc i ty.
The same ex am ple can al so be con sid ered with re gard to a fa ther trav el ing in a rock et mov ing at ro-
ugh ly 99% of the speed of light and his son who stays on Earth. According to Einstein, if the fa ther was

27 years old when he set out and his son three, when the fa ther comes back to the Earth 30 years lat er
(in Earth time), the son will be 33 years old, but his fa ther will be on ly 30. 135
The fact that time is rel a tive af fects not on ly the slow ing or ac cel er a tion of clocks, but the en tire ma te -
ri al sys tem, right down to the lev el of sub a tom ic par ti cles. In an en vi ron ment in which time is fore short -

en ed, proc ess es such as the heart beat, cell di vi sion and the ac tiv i ties of the brain take place more slow ly.
A per son is thus able to con tin ue go ing about his dai ly life with out re al iz ing the slow ing down of time.
The par ti cle phys i cist Dr. Jim al-Khalili made the fol low ing com ments on a ra dio pro gram:

Both Einstein’s Theories of Relativity say that trav el ling to the fu ture is al lowed; in fact, we’ve prov en it ex -
per i men tal ly. One way is to trav el very fast, so you head off in a rock et, close to the speed of light and come

back again. Because you’ve trav elled very fast, your clocks will have run more slow ly and so, if you’ve been
away for one year ac cord ing to your clock, may be ten years have gone by on Earth. So, in es sence you’ve
trav elled nine years in to the fu ture. Another way to trav el to the fu ture is to or bit a mas sive star. If you do

it for a year, again, you may come back to find again that ten years have elapsed on Earth. So ei ther way,
time trav el to the fu ture is pos si ble. 136
