Penrose’s Conformal Cyclic Cosmology (CCC) versus Maha Vishnu’s Breath

Penrose’s CCC: non-oscillating, non-contracting, single-universe model

In CCC the universe undergoes successive “aeons,” each beginning with a Big Bang–like hot phase and ending in an infinitely dilute, smooth state. There is no physical contraction or bounce between aeons—only an asymptotic exponential expansion that, under a conformal rescaling, maps cleanly onto the next cycle.

• No oscillation of the scale factor
• No contracting phase or classical “crunch”
• A single, unbranching spacetime (no ensemble of bubbles or parallel universes)

Maha Vishnu’s Breath: oscillatory, contracting, multiverse cycles

In Vedic cosmology the cosmic day of Maha Vishnu manifests as an exhalation (creation) and his cosmic night as an inhalation (dissolution, or pralaya). This rhythmic breathing:

• Drives an endless loop of expansion and contraction
• Involves complete dissolution of all universes at each pralaya
• Yields innumerable universes born from Vishnu’s navel—an explicit multiverse of coexisting cosmic bubbles

Direct contrast

• CCC postulates a non-oscillatory, ever-expanding spacetime that merely “recasts” its remote future into a new Big Bang without contraction or branching
• Maha Vishnu’s model is intrinsically oscillatory (exhalation/inhalation), features a true contraction (pralaya), and spawns multiple universes each cycle
