A highly accelerated object near the speed of light,should be seen contracting faster,than the speed of light.Maybe the contraction could not be observed?
valentin mano said:O.K.It'snot about Lorentz contraction,but the contraction near the speed of light with acceleration.

valentin mano said:Lorentz contraction also doesn't describe the reduction in length of an accelerated object.
So,describe it.
You are saying that, with enough acceleration, an object can shrink at any speed, even that exceeding speed of light. That is wrong.valentin mano said:A highly accelerated object near the speed of light,should be seen contracting faster,than the speed of light.
Assuming that it didn't permanently deform due to a too fast acceleration, and after acceleration effects have died out, it is predicted to be Lorentz contracted according to measurements done with the "rest" system.valentin mano said:Are You saying that,if an object is accelerated,it doesn't seem to be contracted?
Objects are shorter if they move fast, not if they just accelerate but are still moving slowly.valentin mano said:Are You saying that,if an object is accelerated,it doesn't seem to be contracted?
Here the Lorentz contraction with acceleration is described in detail:valentin mano said:Lorentz contraction also doesn't describe the reduction in length of an accelerated object.

It seems that what you have in mind is to start changing the velocities of the component particles all at the same time. But if two events are simultaneous in one inertial coordinate system, they're not simultaneous in another (unless the velocity difference between them is zero). So what inertial coordinate system will you use to define what "the same time" means? I'm guessing that what you have in mind is "the one in which the object was originally at rest".valentin mano said:Let's change the velocity of 1-metre measuring-rod from 0.9c to 0.9999c for one nano-second.What kind of a contraction shall we observe from
our stationary system?
This paper cites also the paper I mentioned in #14 above.valentin mano said:http://arxiv.org/ftp/arxiv/papers/0712/0712.3891.pdf.[/PLAIN] I've read it just a few moments ago. It solves some of my questions.Thanks for the time!
Lorenz contraction, also known as length contraction, is a phenomenon in special relativity where an object appears shorter in the direction of its motion relative to an observer.
Lorenz contraction was first proposed by Dutch physicist Hendrik Lorentz in 1892 as a way to explain the results of the Michelson-Morley experiment, which showed that the speed of light is constant regardless of the observer's frame of reference.
Lorenz contraction is closely related to time dilation, which is the slowing down of time for objects in motion. As an object's length decreases due to Lorenz contraction, its time also appears to slow down for an outside observer.
Yes, Lorenz contraction is a real physical effect that has been confirmed through numerous experiments and is a fundamental component of the theory of special relativity.
Lorenz contraction is most noticeable at speeds close to the speed of light, which is not achievable in everyday life. However, it can be observed in particle accelerators such as the Large Hadron Collider, where particles are accelerated to very high speeds and their length is measured to be shorter than when at rest.
