Laying the ghost of twin paradox
(Society of Thermal Engineers of Serbia, 2009)
Someone's true age is not written in his ID, but in his biomarkers. Aging process is not caused by time passing, but by thermodynamically laws. Entropy, extent of metabolic reaction, and temperature are Lorentz invariant, ...
