You have probably heard people saying that the problem with quantum mechanics is that it's non-local or that it's impossible to understand or that it defies common sense. But the problem is much simpler, it's that quantum mechanics is a linear theory and therefore doesn't correctly reproduce chaos. Physicists have known this for a long time but it's rarely discussed. In this video I explain what the problem is, what physicists have done to try and solve it, and why that solution doesn't work.

You find the estimate for Saturn's moon Hyperion in Zurek's review https://arxiv.org/abs/quant-ph/0105127
A much easier to digest and more readable review by Michael Berry is here: https://michaelberryphysics.files.wordpress.com/2013/07/berry337.pdf
And you can find a brief summary on Sean Carroll's blog
