Bianchi Type I model of universe with customized scale factors

Understand

According to standard cosmology, the universe is homogeneous and isotropic at large scales.

• However, some anisotropies can be observed at the local scale in the universe through various ways.
• Here we have studied the Bianchi type I model with customizing the scale factors to understand the anisotropic nature of the universe.
• We have considered two cases with slight modifications of scale factors in different directions in the generalized Bianchi Type I metric equation, and compared the results with the $\Lambda$CDM model and also with available cosmological observational data.
