This article examines the seven most significant fundamental constants of nature — the speed of light (c), Planck's constant (h), the gravitational constant (G), the fine structure constant (alpha approximately 1/137), the elementary charge (e), the Boltzmann constant (k), and the cosmological constant (Lambda) — exploring both their physical significance and the deep mystery of why they have the values they have rather than any other. The fine structure constant receives particular attention as the dimensionless constant that has most perplexed physicists: Richard Feynman described it as one of the greatest damn mysteries of physics and noted that all good theoretical physicists put this number up on their wall and worry about it; Paul Dirac called it the most fundamental unsolved problem of physics; Wolfgang Pauli died in hospital room 137, finding significance in the coincidence. The article documents the consequences of fine-tuning: small deviations in the fundamental constants would produce a universe in which atoms cannot form, stars cannot burn steadily, carbon cannot be synthesised, and complex life is impossible. Three candidate explanations are examined: a yet-unknown fundamental principle, the weak anthropic principle, and the multiverse hypothesis. The Vedic concept of Rta — the invariant cosmic ordering principle that appears 390 times in the Rigveda — is presented as the ancient Indian philosophical framework that anticipated what modern physics calls the mathematical structure encoded in fundamental constants.
