Spinning black holes store rotational energy that can be extracted; when a black hole is immersed in an externally supplied magnetic field, reconnection of magnetic field lines within the ergosphere can generate negative energy particles that fall into the black hole event horizon while the other accelerated particles escape stealing …

The Unruh effect was described by Stephen Fulling in 1973, Paul Davies in 1975, and William Unruh in 1976. Sometimes called the Fulling-Davies-Unruh effect, it suggests that if you fly through a quantum vacuum with extreme acceleration, the vacuum no longer looks like a vacuum: rather, it looks like a …

In a paper published this month in the journal Physical Review Letters, an international team of physicists described a new mechanism of dark matter production. Baker et al. described a new mechanism of dark matter production: if dark matter particles acquire mass during a first order phase transition, it is …
