If you traveled the speed of light for 14 years how old would someone on earth be if they were 20 when you left?

It would require an infinite amount of energy to propel a mass to the speed of light.
But he answer depends on what you mean. From your perspective (the traveler), the person on earth would not age at all by the end of a one way trip directly out bound. They would still appear to be 20 years old, as the signals from that person would not have aged.
If the person traveled 7 years out and 7 years back (at very close to light speed), the earth bound person would be 34, while the traveler (you) would still be the same age as when you left.
The theory that accounts for this is known as "special relativity," and if you know algebra a function to calculate relative ages is: to = ts/(1 - v2/c2)(1/2)
Where t=time, o=objective (earthbound), s=subjective (traveler), v=velocity and c=speed of light. The 1/2 exponent indicates the square root of (1-v2/c2).

can you find the speed of someone in space if one year in his spaceship = 50000 years on Earth?
No, it is not possible to determine the speed of someone in space based on the information given. To calculate speed, we need to know the distance traveled and the time it took to travel that distance, and in this case, we don't have either of those values. We know that one year on the spaceship is equal to 50000 years on Earth, but that does not provide us with any information about the speed of the spaceship.
How long would it take to travel at the speed of light from Earth to Aldebaran?
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
How many days does it takes to get to the moon from the earth?
At the speed the Apollo spacecraft traveled, it took three to three and a half days.
How long would it take to travel to mars from earth using impulse engines set to maximum?
The Apollo spacecraft en route to the moon traveled at a nearly 25,000 miles per hour. This is the fastest mankind has ever traveled. The earth, at the equator is roughly 25,000 miles in circumference. This makes the math easy, your answer is 1 hour.
How many light years does it take to get from earth to neptune?
At the speed of light it takes 4 hours 11 minutes and 27 seconds.
How long will it take if you traveled at the speed of light to get from earth to a comet?
That will completely depend on where the Earth and the comet are in their respective orbits. No single answer is possible.
Did Einstein traveled the time?
yes because in youtube it shows that someone or something can travel in the speed of light which is time travel
What is the distance traveled in a year at the speed of light?
It is known as a light year.
How many seconds would it take to travel to the sun if you traveled at the speed of light when the radius of the earth is 6371 km equals 3960 mi?
It would take about 496 seconds to travel to the sun at the speed of light.
What is the distance in a year traveled at a speed of light known as?
It is known as a light year.
How did early astronauts travel the speed of light?
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
Did sloths used to travel at the speed of light but got tired?
No. They never traveled at the speed of light, and have always appeared tired.
How fast could you get to the sun at light-speed?
If you traveled at the speed of light (a current impossibility), you would travel from Earth to the Sun in an average of 8 minutes. Or would you? I suspect that you would burn up well before the 8 minutes were up.
Who traveled faster than the speed of light?
Nobody in the real world.
What is the fastest speed someone has traveled on a pogo stick?
6.5km/h
What is the fastest speed that a car has traveled on earth?
it is a three wheeled car and the speed is745mphand it is called SSC
How do you make a timemachine?
the only way i know how to time travel is that if you started at earth and went for a huge distance traveling at the speed of light (299,792,458 meters a second or 186,282 miles per second) then when you come back to earth you would have traveled in time. But the problem is we have nothing that can go near the speed of light and a lot of scientists say absolutely nothing can go faster then the speed of light.
