2d Stringy Black Holes and Varying Constants
Motivated by the recent interest on models with varying constants and whether black hole physics can constrain such theories, two-dimensional charged stringy black holes are considered. We exploit the role of two-dimensional stringy black holes as toy models for exploring paradoxes which may lead to constrains on a theory. A two-dimensional charged stringy black hole is investigated in two diff...
متن کاملBook Review: The Constants of Nature and Just Six Numbers, Volume 51, Number 10
Just Six Numbers Martin Rees Basic Books, 2001 208 pages, $14.95 (softcover) ISBN 0-465-03673-2 (softcover) ISBN 0-465-03672-4 (hardcover) Consider the two constants G and G. The first G arises frequently when we manipulate special functions. We represent this G by dozens of series and integrals, we study its continued fraction expansion, and we calculate millions of its digits. Any mathematici...
متن کاملMore than Nature Needs
1870. United Kingdom. Scenes from a divorce. Alfred Russel Wallace, the coinventor with Darwin of the theory of evolution through natural selection, completely captivated by the melodious song of the sirens hailing spiritualism landed definitively on the controversial shores of the treason. In effect, with his essay The Limits of Natural Selection as Applied to Man, Wallace turned his back on t...
متن کاملConstancy of the Constants of Nature 1
The current observational and experimental bounds on time variation of the constants of Nature are briefly reviewed.
متن کاملIn Spacetime and the Constants of Nature *
The proposal that wormholes in spacetime cause the cosmological constant A to vanish is reviewed, and its implications are studied. Wormholes also drive Newton's constant G to the lowest possible value. The requirement that G is at its minimum determines, in principle, all other constants of Nature. In practice, the values of fundamental constants other than A cannot be predicted without a deta...
