Do black holes have a back door?

6 August 2016 Astronomy Now

The laws of physics as we know them cease to apply to black holes in their deepest regions. Large quantities of matter and energy concentrate in a gravitational singularity, where space-time curves towards infinity and all matter is destroyed. Or is it? A recent study suggests that matter might in fact survive its foray into these space objects and come out the other side.

Race to detect gravitational waves intensifies

31 March 2015 Astronomy Now

One of the great challenges in astrophysics is the detection of low-frequency gravitational waves — elusive ripples in the fabric of space-time caused by extremely energetic and large-scale cosmic events. To this end, the National Science Foundation (NSF) has awarded the North American Nanohertz Observatory for Gravitational Waves $14.5 million over 5 years.
