Now the alternative scientific meaning of the mantra step by step:
We observe that when an ordinary fan with a speed of 900 RPM moves, it makes noise. Then, one can imagine, what great noise would be created when the galaxies move with a speed of 20,000 miles per second.
Therefore, it was the first ever revolutionary idea to identify formless God with a specific title (form) called upadhi. Until that time, everybody recognized God as formless and nobody was prepared to accept this new idea. In the Gita also, it is said, "Omiti ekaksharam brahma", meaning that the name of the Supreme is Om , which contains only one syllable (8/12).
Once the form of a person along with the name is known to us, we may locate the specific person. Hence the two titles (upadhi) provide the solid ground to identify the formless God, Vishvamitra suggested. He told us that we could know (realize) the unknowable formless God through the known factors, viz., sound Om and light of suns (stars). A mathematician can solve an equation x2+y2=4; if x=2; then y can be known and so on. An engineer can measure the width of a river even by standing at the riverbank just by drawing a triangle. So was the scientific method suggested by Vishvamitra in the mantra in the next portion as under:-
//BHARGO DEVASYA DHEEMAHI:
The rishi instructs us to meditate upon the available form (light of suns) to discover the formless Creator (God). Also he wants us to do japa of the word Om (this is understood in the Mantra). This is how the sage wants us to proceed, but there is a great problem to realize it, as the human mind is so shaky and restless that without the grace of the Supreme (Brahma) it cannot be controlled. Hence Vishvamitra suggests the way to pray Him as under:
1) The total kinetic energy generated by the movement of galaxies acts as an umbrella and balances the total energy consumption of the cosmos. Hence it was named as the Pranavah (body of energy), this is equal to 1/2 mv2.
