Length contraction or just a false impression..?

Question

Is there really length contraction or it is because the object is travelling at too fast a speed thus before light can be reflected from the front of the object to the observer, the back of the object has already catch up. Thus this created a false impression to the observer that the object length has contract while the true is it just seems to contract.. A false impression created by the eye..

I not sure whether is it right to think in this way.. feel free to comment

Answer 1

If you are moving close to the speed of light, everything looks and feels normal to you. If I am at rest with respect to you it's only the way I measure things in your reference frame because the speed of light is finite.

Answer 2

Yes, there really is length compression. The faster an object moves, the shorter it becomes in the direction of travel.
This effect, predicted by relativity, has been accurately measured at speeds as low as 10,000 miles per hour -- a small fraction of the speed of light. It's fun to come up with ways to measure this, because remember: any measuring device (ruler, tape measure, whatever) going as fast as the object you're trying to measure is *also* compressed...:) But clever scientists have pulled it off. And there's no eye involved to be tricked, the measurements are done without any eyes involved at all.

Answer 3

If it were a "false impression" (to the people in the object), it would be because you seemed to take the front measurement first, then the back measurement later, when the object had moved forward. In other words, you think you took the measurements simultaneously but they don't see it that way.

Answer 4

I studied Length contraction law, it was explained & prooved
For me, i think it is true, becouse its all about relativity

What do u think ??
