Obviously theoretical but if I took a light year long stick and say pushed a button at the other end would that button be pushed at the same time for me as say someone standing at the button? How does the frame of reference work when physically moving something? And could that “work” as a method of instant communication?

I don’t understand the explanations in some of these comments. Can someone please ELI2 😅
If I have a wooden pole, from earth to the moon, and I push it toward the moon, if I see it actually move say 1 meter, why will that take so long for the other end? Wouldn’t it be instant since it’s not like the rod gets shorter. If I can see it move (let’s pretend it’s weightless) then where does it “go” while it is moving?
