Scalar Perturbations

Scalar Perturbations is a type of primordial density fluctuation in the early universe that belongs to the class of cosmological perturbations characterized by spatial variations in the energy density and gravitational potential, distinguished from vector and tensor perturbations by its invariance under spatial rotations and its role in seeding large-scale structure formation through gravitational instability.
