After the Final Photon by Norazha Paiman

entropy wins, slow
the last star dims its language
silence without ears

by Norazha Paiman

The heat death of the universe is thermodynamics made personal. Over timescales exceeding 10¹⁴ years, the last Population III stars will exhaust their fuel. Black holes will eventually evaporate through Hawking radiation. Entropy, the measure of disorder in a closed system, trends toward maximum.

What remains is not darkness in any dramatic sense, but equilibrium: a universe with no temperature gradients, no available energy, no work possible. No observers. The second law of thermodynamics does not negotiate.

“Language” in line two gestures toward stellar spectroscopy, the idea that stars speak in emission lines, in wavelengths we decode. When the last photon redshifts into nothing, the question becomes genuinely philosophical: can silence exist without a witness?

The Big Decay Theory by Martina Matijević

our universe weds
the Hawking radiation
final cul-de-sac

by Martina Matijević

Researchers from Radboud University now believe the universe will decay faster than previously thought, due to Hawking radiation. White dwarfs and black holes will evaporate in about 10⁷⁸ years, much sooner than the older estimate of 10¹¹⁰⁰ years. Surprisingly, black holes and neutron stars will disappear around the same time.
