While exploring connections between quantum and cosmological scales, I found an exact numerical identity that seems surprisingly physical, not just coincidental.
The ground state energy of the hydrogen atom is: $$ E_H =13.605693 \text{ eV} = 2.179872361×10^{−18} \text{ J} $$
This is the energy of the simplest bound quantum system in nature.
The oldest known star HD $140283$ (the "Methuselah Star") is a well-studied, extremely metal-poor subgiant — essentially a pristine hydrogen/helium object — with an age estimated as:
$$ T_M = 14.46 \pm 0.8 \text{ billion years} $$
At the upper end of this uncertainty, we have:
$$ T = 14.46 + 0.8 \text{ by}= 14.54 \text{ by} = 4.587 \times 10^{17} \text{ seconds} $$
Multiplying these two quantities gives:
$$ E_H \cdot T = (2.179872361×10^{−18} \text{ J})\cdot(4.587 \times 10^{17} \text{ s}) = 1 \text{ Js} $$
This is exactly one joule-second — the classical unit of action.
This seems to imply:
Over the full age of the oldest known star, a hydrogen atom’s bound electron accumulates one joule-second of classical action.
This surprised me for its dimensional clarity and numerical precision — involving no tuning or approximations, only observed constants.
My Question
Has this identity:
$$E_H \cdot T = 1 \text{ Js}$$
been previously studied, interpreted, or connected to any known principle — e.g., in:
Dirac’s Large Number Hypothesis?
Quantum cosmology?
Action-based formulations of physics?
Is this just numerology, or could it represent a deeper relationship between atomic systems and cosmic timescales?
