Query: Super-Chandrasekhar limiting mass white dwarfs as emergent phenomena of
  noncommutative squashed fuzzy spheres   The indirect evidence for at least a dozen massive white dwarfs violating the
Chandrasekhar mass-limit is considered to be one of the wonderful discoveries
in astronomy for more than a decade. Researchers have already proposed a
diverse amount of models to explain this astounding phenomenon. However, each
of these models always carries some drawbacks. On the other hand,
noncommutative geometry is one of the best replicas of quantum gravity, which
is yet to be proved from observations. Madore introduced the idea of a fuzzy
sphere to describe a formalism of noncommutative geometry. This article shows
that the idea of a squashed fuzzy sphere can self-consistently explain the
super-Chandrasekhar limiting mass white dwarfs. We further show that the
length-scale beyond which the noncommutativity is prominent is an emergent
phenomenon, and there is no prerequisite for an ad-hoc length-scale.
