GRAVITY may have the power to create quantum monsters. A strong gravitational field can induce a runaway effect in quantum fluctuations in apparently empty space, resulting in a burgeoning concentration of energy that may explode stars or create black holes. So say Daniel Vanzella and William Lima at the University of São Paulo in Brazil.
Quantum phenomena are not thought to have any significant influence over processes on the astrophysical scale, such as the compression of gas clouds into stars. That’s the domain of gravity, which in turn is not supposed to…
