If I hold up something solid the length of the extended slinky the bottom would move imminently since it's constricted tho?

His name is Paul Cadden
Here's his Facebook page

I bet he makes his own dirty paintings and keeps them to himself. Really he can photodraw everybody in any position.
As long as a photograph of it exists! Most of these sorts of works use a reference image.

It's incredibly impressive, but I can't help but why people who have such technical skill always seem to try to recreate photographs of relatively mundane things. If I could make a drawing photorealistic, I'd be trying to create things not otherwise feasible by any other medium such as fantastical creations of things only dreamed about - not just a drawing that looks like something any person with a camera could do.
But maybe this tends to be the case because photorealistic drawings are only possible when using photos as a base.

I don't see what that has to do with the troll science pic which doesn't make any sense. A stick that's 1ly long has almost no distance to travel at all. How can you say its traveling at the speed of light?
Could a 1 lightyear long stick theoretically be used to send a morse code message over 1 lightyear in a few seconds?
I have wondered this as well. It's not that the stick would be traveling faster than light, but rather you could essentially send information faster than the speed of light.
.QUESTION:
Let's say I have a metal rod about a half an inch thick and 300,000 kilometers long. Then say I give one end of said rod a mighty whack with a hammer, propelling it forward by one inch in a mere fraction of a second. My questions is, wouldn't the impact of my hammer cause the other end of the rod to move forward one inch just as rapidly as the end where I whacked it? And would this violate Einstein's law that states that nothing can move faster than "C"? Or would the far end of the rod have to wait one second after my whacking my end before moving forward by one inch?
ANSWER:
Have you thought about the implications of your question? I figure the mass of the rod would be about 1010 kg. Suppose that you exert a constant force such that after 0.1 s it is moving with a speed of about 0.5 m/s; it would have moved about an inch in this time. The force is the change in momentum divided by the elapsed time so, roughly speaking, the required force is about 1012 N. Where are you going to get such a force? Anyhow, to the meat of your question: no, the other end would not start moving instantaneously. It could not begin moving until at least one second later than your end started moving for the reason you state: no information can travel faster than c. In reality, it would be much longer than one second because your "mighty whack" will compress the rod and this compression will move with the speed of sound in the metal and this compression is what travels to the other end to move it.

It's called Longitudinal wave.so the longer something is, if you tried to move it, it'd compress before expanding? That doesn't sound right.

That's implying that even an object 12" long compresses slightly when you move it along its length.
Do you have any background information for this gif?
