am splitting off this entry from exotic smooth strcuture, in order to facilitate linking to specifically the case of exotic 7-sphere.
Accordingly, so far the bulk of the entry is just copied over from the corresponding section at exotic smooth structure,
But I also added a new paragraph,
and that is what motivated me to split this off. Namely it occured to me that from the point of view of M-theory on 8-manifolds, Milnor’s classical construction of exotic smooth 7-spheres as boundaries of 8-manifolds is very particularly the construction of near horizon limits of black M2-brane spacetimes in the context of M-theory on 8-manifolds.
This must be known in the literature, and I’d like to collect what is known about it. So far I found a brief comment in this direction, in section 3.2 of
Will be adding more as I find more.

added the missing reference:
(I guess this was lost when we split this entry here up from exotic spheres)
