Breezy+Length+Contraction

Length contraction is just an addition to time dilation. It says that length is viewed differently when someone is on the move. A 12 inch ruler held by someone will not appear to be 12 inches to someone who is moving at a high speed. To obtain the “proper length” of an object, the object needs to be at rest. This is much easier to measure, then when the object is in motion. When you measure a moving object, you need record the time in which you measured the object. But the time needs to be exactly the same, or else your results will be skewed. But since doing something simultaneously is relative, then you’re the only one who is going to agree that that is the 100% correct length for the object. Since time is relative when traveling, thanks to the Lorentz factor, distance will become relative to a degree. Since D = VT, velocity doesn’t change, but the amount of time for someone does. This means that distance will change. It appears to take a smaller amount of time for a man in a spaceship to travel a distance then it does for the people on Earth. This means that distance will be shorter for man in a spaceship. http://www.5min.com/Video/Length-Contraction-174069895
