In this article, we investigate the mechanism of cosmological expansion and inflation by modeling dark energy as a four-dimensional continuous medium, with its elastic deformation described by a four-dimensional vector field. We demonstrate that when the bulk modulus of this cosmological medium is K = 1.64 × 10109 N\cdotm-2, the dark energy density, corresponding to the stress-energy associated with the deformation of the medium, decreases by a factor of ∼ 10122 while the scaling factor expands from ∼ 10-60 to ∼ 10-32 over approximately 10-42 seconds during cosmological inflation in the early universe. Our analysis suggests three potential new physical phenomena for future investigation: detecting longitudinal modes of elastic waves, examining discrepancies in the redshift of light from the early universe, and fitting supernova curves using the parameters introduced in our model.
