# Faster than light?

Hi, I have no actual knowledge in physics, but Iv'e been wondering about a specific (theoretical) idea that I had for quite a while now, so I decided to open an account here and ask if it's possible:

Let's say we have a very long pole made out of metal that reaches from earth all the way to some inhabitable planet 1 light year away.
If we were to pull on that pole 1 foot towards us, would it also move in the far away planet, instantaneously?
Because if it does, isn't that faster than light?
And if not, does that mean the pole's length increased by 1 foot?
And if it is longer now, when the other end of the pole actually moves, will the pole go back to it's original length?
Because if the pole will eventually go back to it's original length, that would mean that metal is an elastic material.

I feel like there are too many contradictions if the answer to my first question is no.
I know it's not possible to actually execute this, but in theory?
