Muons are formed from cosmic bombardment and they fall towards the Earth.
So here's the problem: Muon's have really short lifetimes. So short that they won't be able to reach the Earth in time before they wink out. However, we detect more muons than we should be.
The solution:
On Earth, we witness Time Dilation of the muon, which explains its longer lifetime.
From the Muon's frame, its lifetime is the same, but the distance between itself and the Earth is length contracted. Simple, right?
Now here's the conundrum: Why should the distance between the muon and the Earth be length contracted and not the other way round? Doesn't length contraction work both ways?
I'll leave you to think about it.
