The indirect evidence for at least a dozen massive white dwarfs violating theChandrasekhar mass-limit is considered to be one of the wonderful discoveriesin astronomy for more than a decade. Researchers have already proposed adiverse amount of models to explain this astounding phenomenon. However, eachof these models always carries some drawbacks. On the other hand,noncommutative geometry is one of the best replicas of quantum gravity, whichis yet to be proved from observations. Madore introduced the idea of a fuzzysphere to describe a formalism of noncommutative geometry. This article showsthat the idea of a squashed fuzzy sphere can self-consistently explain thesuper-Chandrasekhar limiting mass white dwarfs. We further show that thelength-scale beyond which the noncommutativity is prominent is an emergentphenomenon, and there is no prerequisite for an ad-hoc length-scale.
