With respect to this Prapancha (universe) which is primarily made up of Pancha Bhoota (the name itself states it is pra-pancha) - shastra refers to this as "Prakriti" -  Jagat and Vishwa these 2 words also in one sense means world and in other sense the meaning is universe. - Rtam (Rytam) - the order is the way this exists. Prakriti also manifolds in multiple forms and shapes. Pancha Bhoota is linked to human beings with Pancha Tanmaatras - five senses. This is also referred to as Shakti

The sixth thing that governs this Prapancha is conciousness - that which governs prakriti is "Purusha".

- the creation takes place with the unification of Prakriti and Purusha in language it is Prakriti (root /stem) and Pratyaya (suffix - suffix is a bad translation however as no alternative I use it) -thus language is in a way the world or universe - we think in words (meanings), we see in words (meanings), we understand every thing in words (meanings). Thus Mahakavi Kalidasa says "Vaagarthaaviva samprkthau..." in his mangalacharam of Raghuvamsa mahakaavyam. however NilakanTa dikshita says both (Shakti /Shiva - Vaak /Artha) are not separate thus he says in his mangalacharana sloka of NilakanTa-Vijaya Mahakaavyam.

Veda says that there is Avinaabhaaba sambanda (inseperable connection) between the word and meaning - thus Prakriti and Purusha. Even Maharishi Dattatreya says in Avadoota Gita same. (image of the sloka is attached).

Prakriti, Purusha, Brahma from the stem Brahman (not Brahmaa or Brahmam) - all these things are discussed in detail in 13.20 - 13.23 and 8th chapter in Bhagavatgita - however understanding these slokas require some shastra background - vyakarna, nyaya and mimamsa or Vedic background Veda (artha) and Vedaangam (Vyakarana) knowledge - else the understanding will not be complete. Even though Bhavadgita being the Veda /Vedanta saaram and tries to compress and simplify everything in 700 slokas it still needs the same amount of Shraddhaa - only then our understanding emerges.

4.39 - Gnaanapara-samyatendriyah shraddhaavaan labhate gnaanam. (in anvaya order) - the one who is stedfast focused and turns all his senses towards gnaanam attains Gnaanam

These things are dealt in Vedas in many places -i.e:  language, the phenominal world, life, brahma etc. - not to mention Upanishads  - which is full of such discussions

Such is the focus on Science in Vedas - which we can call as Subjective Science - deals not just with objects (made up of Pancha Bhoota and achetana - non-living ) but with Subjects - which are living and with conciousness.

I'm writing many things but I'm not an expert in any of these, just a student describing what ever his observations in his educational journey. In case of any discrepancy or mistake please correct...
