### Is it possible to rotate a very very long (almost infinite) and rigid pole such that its end reach the speed of light? [duplicate]

$v=\omega r$ relation shows that even with a fixed $\omega$ and large $r$, the end of the pole can be rotated at a high speed. So if I make pole sufficiently long such that $v=c$, will it be possible ...
