What are the opposite words for macro-cosmo?

The word "macro-cosmo" refers to the vast universe or cosmos as a whole. Its antonyms are "microcosm" and "smaller world." A microcosm is a small-scale representation of a larger system or universe. It's a miniature version that reflects the characteristics of the larger system in a condensed form. In contrast, the smaller world refers to a limited or localized environment, which is smaller in scale than the macro-cosmo. It's an antonym that describes anything that's restricted to a specific space or time. While the macro-cosmo is vast and boundless, the smaller world and microcosm are much more finite and constricted.
