Objects like an unbreakable stick are still composed of atoms suspended in space and held together by the fundamental forces of nature. When you push on one end, the other end doesn’t immediately move with it but rather the object experiences a wave of compression traveling through it. This wave of compression travels faster than we can perceive but still cannot travel faster than light.
Look up why arrows bend after they’ve been released by a bow, it’s essentially the same mechanic.
I’m a senior software dev that uses AI to help me with my job daily. There are endless tools in the software world all with their own instructions on how to use them. Often they have issues and the solutions aren’t included in those instructions. It used to be that I had to go hunt down any references to the problem I was having though online forums in the hopes that somebody else figured out how to solve the issue but now I can ask AI and it generally gives me the answer I’m looking for.
If I had AI when I was still learning core engineering concepts I think shortcutting the learning process could be detrimental but now I just need to know how to get X done specifically with Y this one time and probably never again.
