The approach of Science in the Vedas is that of searching for the ultimate truth, absolute knowledge. The knowledge encompassed there is an expression of omniscience. The Vedic Cosmology and Science of Nature is therefore derived from Brahm
Vidya – Supreme Knowledge, which is the nucleus of all the knowledge. The search of Vedic Science finds the eternal truth
in the cosmic as well as the sublime. It begins with "Athato – Brahmajigyasa"; meaning: let us now enquire about the Brahm.
In other words, the quest of Vedic Science is top-down whereas that of the modern science is bottom-up. The latter has begun its journey from the gross, physically perceivable and has reached only up to the subtle atoms of matter and physically perceivable energy and accepted the fact that there do exist subtler particles and all pervading energy. The omnipresent perpetual Consciousness
Energy is referred in the Vedic literature as Brahm
– the self-existent cause of all existence, of all experiences, of all knowledge, of all manifested and sublime truth. The Brahma Sutra remarks – "That which exists in the infinite cosmos also exists within the tiny atom. This is how the Brahm
is indwelling in the infinite cosmos".
The Brahma Sutra (2-2-4) and Newton’s Law of motion have a striking similarity in explaining the cause of motion as the (gravitational) force applied. Newton and Keppler also agree with each other in this context with regard to the motion of the planets but they do not explain the source of the mutual gravitation of the different planets. Here again the Vedic concept of "enormous levels and forms of the unified Cosmic Force" provides the complete answer.
According to the Ryle theory whole universe was born about 10,000 billion years ago as a result of very great explosion (big bang) of a solid mass. Another theory - The Steady State Theory was propounded by Bondy and Hoyle that whatever is being born is emerging from naught. It is dynamic and the space left by it is filled by another creation also arising from vacuum. But the Vedic science holds a different, rather more comprehensive view explaining the relativity and perennial complementarity of creation and non-creation, matter and non-matter and existence beyond time and space. The Shwetashwatar Upanishad for example states that –– the perpetual sat (the pure eternal light, the infinite impulse, of Brahm) manifests itself in three forms (called three gunas, three intrinsic faculties of Nature) namely sat, raja and tama.
