Newfag here. I'm assuming this is not correct because of Trollface being featured in the image. Would someone please explain?

well basically one atom has to poke the next one, and that one the next, and that one the next.

instead of them all moving at once.

Gotcha. So, it's like a wave, which is limited by the speed of light.

exactly

>>1824109
Even more accurate would be to say it is limited by the speed of sound in that medium (a stick in this case). The only case where it "could" break the speed of light would be if the stick were perfectly rigid, and incompressible, a case in which waves propagate with infinite speed. Of course this case is not possible.

Actually, the way it would work would be a material that is perfectly rigid, but is not very dense at all.

Think about it, sound travels faster through gases.

One day one of these physics troll images is going to really discover something, changing the world as we know it

>> No.1824224

One of the most confusing things in physics is that if you're traveling at the speed of light, then light is still traveling past you at the speed of light. It's the only known universal constant.

OP, I think it would be more practical to use wormholes to communicate over long distances.

Pic related.

Sound travels slower in gases. Alot slower actually.

Look at whales. They can communicate so well over such huge distances (hundreds of miles) because sound travels so much faster in water than in air.

What if the stick was made of a bose einstein condensate, and thus acted as one giant atom?

This solution does not use gasses!

interesting predicament

>> No.1824287

What about non material stuff like thoughts?

When I want to think of an elephant I do in the same moment. It happens instantly. Therefore thoughts are faster than light.

Or liquid in a tube? That would be incompressible and rigid right? Or does the tube mess it up?
