Why isn't the universe uniform and symmetric?

The second law of thermodynamics, according to which the total entropy of an isolated system always rises with time or, in the best-case scenario, stays constant when the system is in a steady state or going through a reversible process, is what governs our universe.

Since "uniform" and "symmetry" are inversely related to entropy—that is, they are the exact opposite of what entropy means—our universe cannot be uniform or symmetric.

According to Wikipedia, "The asymmetry between the past and the future and the irreversibility of natural processes are explained by an increase in entropy."

Here is a Wikipedia link that may be of use to you.

I hope this is useful.

The universe isn't uniform and symmetric due to several factors, including gravitational interactions between cosmic structures, the expansion of the universe, and the distribution of matter and energy influenced by various physical processes such as inflation and cosmic inflation. Additionally, quantum fluctuations during the early universe's evolution also contribute to the observed non-uniformity and lack of symmetry.
