Close Brushs With the Effectss of Time Dilation

How does it experience to be traveling velocities near that of the velocity of visible radiation? What is it like to

return to Earth to happen that your best friend who was the same age as you is now older

than you? You might speak to a adult male named Bob Smith. Bob late returned from his trip

to the border of the existence and we were fortunate plenty to speak to Bob about what he

experienced on his journey. We besides got the chance to speak with Bob & # 8217 ; s close friend,

Jill, who eyewitnessed the effects of clip dilation on Bob.

Ten old ages ago today, Bob Smith boarded his starship and journeyed to the border

of the universe analyzing its distance and other belongingss unknown to adult male. The twenty-four hours Bob

left, his friend Jill was standing by his side to offer him farewell.

As Bob took off into infinite

Jill noticed something really curious, Bob & # 8217 ; s ship had seemed to hold shrunk in size. & # 8221 ; It

was amazing & # 8220 ; , said Jill. & # 8220 ; The ship appeared to be half the length it was before! & # 8221 ; Bob,

who was going at 87 % the velocity of visible radiation, on the other manus, did non detect this alteration

in length at all. How could this be, you may inquire? Well, we talked to renowned

scientist, Alberta Einstein and she came up with a theory for us. The viewed length for

an perceiver on Earth is equal to the existent length multiplied by the square root of the

measure one subtraction speed squared divided by the velocity of visible radiation squared. In equation

signifier that is. So if the length of Bob & # 8217 ; s transport on Earth was 53

metres, so to person standing on Earth sing the ship in infinite, the ship would

look to be about 26 metres or half the existent length of the ship. This would

so verify that what Jill saw was really the truth.

While Bob was in the

ship he measured his mass and surprisingly it was more

than he had measured it to be on Earth. Bob & # 8217 ; s mass on Earth was 77.2 kilogram. When he

measured it in infinite it was sizably greater. So once more we asked Alberta if and why this

could perchance be. Again she was able to supply us with an equation to explicate this

phenomenon. Bob & # 8217 ; s new mass is equal to his mass on Earth divided by the square root of

the measure 1 subtraction his speed squared divided by the velocity of visible radiation squared. In

equation signifier that is. So since Bob & # 8217 ; s mass on Earth is 77.2 kgs. , so his

mass on the ship is 593.8 kilogram. As we see, his mass was increased by about

seven times! Belly laugh!

One last thing we should look at is the comparing of Bob & # 8217 ; s age and Jill & # 8217 ; s age after

the trip. To a individual on Earth, Bob & # 8217 ; s trip seemed to take merely 10 old ages. When Bob left,

both he and Jill were both 18 old ages of age. So, when Bob returned from his trip Jill was

28 and surprisingly Bob was younger than Jill. How on Earth could this be possible you

may inquire? Let & # 8217 ; s inquire Dr. Einstein one time more for her input on this state of affairs. Harmonizing to

Alberta, the clip elapsed in Bob & # 8217 ; s frame of mention is equal to the existent clip on Earth

multiplied by the square root of the measure one subtraction his speed divided by the velocity

of light squared. So in equation signifier that & # 8217 ; s.

Therefore, to Bob, the trip seemed to last merely about 4.9 old ages ( or to do it simpler, 5

old ages ) . So when Bob came back he was merely 23 old ages old as opposed to Jill who was now

28 old ages of age.

Quoting Bob, & # 8221 ; Relativity is a really curious thing! It can really unusual effects on

simple things such as mass, length and clip. If I would hold known it would decelerate the

aging procedure, I would hold stayed out much longer! Book me another flight to the Moon!
