Why would'nt this work?
-
I think the standard model says the same thing, tbh....
-
Basically the speed of sound in that material
-
I predict we'll have FTL travel before we can invent a stick that's "unfoldable".
-
You joke, but this is a real problem in computing Obligatory link to Tom Scott video.
-
Matter is made of atoms. Things are only truly rigid in the small scales we deal with usually.
-
Tbh I thought someone would make that joke when i wrote it lol
-
Probably wiggly wiggly

Yeah, everyone else had already answered that, which felt like we're picking apart that specific thought experiment, even though there is actually a much more fundamental reason why it won't work.
-
Even if it were perfectly rigid, supernaturally so, your push would still only transmit through the stick at the speed of light. The speed of light is the speed of time.
-
Damn it even on Lemmy I can't get to the comments before someone else has the samr idea as me ahaha
-
The push would travel at the speed of sound in the stick, much slower than the speed of light

Ok so since there's a bunch of science nerds on here and I'm sleep deprived I'm gonna ask my dumb ftl question.
If you're on a train and you walk towards the front of the train, your speed measured from outside of the train is the speed of the train (T) plus the speed of you walking (W).
So if there was a train inside of that train, and you walked inside of that, you'd go the speed of the outside train, plus the speed of the inside train, plus your own walking speed.
So what if we had a Russian nesting doll of trains, so that the inner most train was, from the outside, going as fast as light and you walked towards the front? Wouldn't you be going faster than light if you measured your speed from the outside?
Didn't come at me with how hard it would be to build a Russian nesting doll of super trains it's a hypothetical and I'm tired.

No it wouldn’t. Sound is air vibration, which has to travel from one place to the next, static atoms don’t have to actually move to a place just transfer kinetic energy to the adjacenct atom, so it would be much closer to the speed of light. Although probably still (relatively (get it??)) slower.
-
A wooden stick is pretty much unfordable in an unaltered state
Or a glass stick -
Not a science nerd. But I would assume the inner trains would like to push forward, stealing some kinetic energy from the outer train because it pushes itself away from the outer train and making the outer train slower or even push back.
-
Probably quantum entanglement, which we (and certainly I) don’t fully understand yet
-
Glass easily bends
-
Sound is air vibration
Sound is not exclusive to air, it can be generalized to vibrations in any media. Whale song and dolphin echolocation are certainly sounds, and we're almost always talking about them propagating in water rather than air.
which has to travel from one place to the next
No, that isn't how sound works. In air this would be a description of wind, not sound.
just transfer kinetic energy to the adjacenct atom
This is actually a good description of how sound waves propagate.

Perfectly rigid sticks don't exist.
