Query: Aging of the Universe and the fine structure constant   In this paper the aging of the Universe is investigated in the frame of
quantum hyperbolic heat transport equation. For the open universe, when t to
\infty, hbar to \infty, c to 0 and fine structure constant alpha is constant.
Key words: Quantum heat transport; Open universe; Fine structure constant.
