# The shortest pendulum would oscillate at the speed of light

Not sure if this idea is correct or not but I have been playing with it in my head for fun. So bear with me…. if you keep halving the length of a pendulum ad infinitum, it would go at breakneck speed right? Sort of like angular momentum when getting closer and closer to the centre of a playground roundabout.

I guess in practice you couldn’t have a infinitesimal length pendulum but in theory maybe you could. Anyways, I found this, which made sense, just doesn’t answer my question. Is this idea silly or a good way to practice physics and maths thinking?

Professor Dave would know the answer to this. But the answer might surprise us. maybe tiny quantum pendulums are why we can’t quite tell where things actually are.
