Bangs, Crunches, Whimpers, and Shrieks : Singularities and Acausalities in Relativistic Spacetimes.

Mostrar otras versiones (1)

Almost from its inception, Einstein's general theory of relativity was known to sanction spacetime models harboring singularities, which involve a breakdown in the very fabric of space and time and, consequently, a failure of the known laws of physics. Here is where noted philosopher of science...
