One of the answers to this MO question implies that loop spaces of $S^n$ for $n>1$ have non-zero homology in arbitrarily high degree.
Is there any simple (or, better yet, geometric) way to prove this?
And if the general result is too strong, is there any simple way to at least show an example of a loop space of a sphere with some high degree non-vanishing homology?
I'm curious because the only sphere loop space I can actually imagine ($\mathbb{Z} \approx \Omega S^1$) does not exhibit this kind of behaviour.
Edit: This is not exactly what I meant. It is clear to me that $H^{n-1}(\Omega S^n) \approx \mathbb{Z}$ because it follows from Hurewicz theorem. I am looking for non-trivial homology in higher degree than $n-1$. I'm sorry if my question wasn't clear, in this case geometric basically means "by hands" or "with little theory", ie. without spectral sequences or cohomology operations.
