<ul><li>Scientists have long believed in the Cosmological Principle, which states that the universe is both homogeneous and isotropic, with no preferred direction.</li><li>Recent observations challenge the assumption of isotropy and suggest possible anisotropies at large scales.</li><li>To investigate this, scientists are using the Euclid Space Telescope and weak gravitational lensing to test whether the universe is truly isotropic.</li><li>If anisotropies are confirmed, it would require a reevaluation of the Standard Model of Cosmology and could lead to a better understanding of the universe.</li></ul>

Is the universe really the same in every direction?
