1:15 Black hole: Kiwi mathematician reacts

Today the first ever image of a black hole was released. 

It's not the black hole in our Milky Way, rather one located in a distant galaxy, and it took a network of eight telescopes across the world to photograph it. 

It's a big deal for the science community, particularly here in New Zealand. In fact this image proves the theory of University of Canterbury's Professor Roy Kerr, which he worked on back in 1963.

This image released Wednesday, April 10, 2019, by Event Horizon Telescope shows a black hole. Scientists revealed the first image ever made of a black hole after assembling data gathered by a network of radio telescopes around the world.

What happens when we die? These questions have posed for centuries, and while religion can offer some clarity, there's no scientific answer as to whether life goes on after death. 

Best-selling author Mary Roach has decided to find out in her new book Spook. She talks to scientists, mediums, researchers and other people who explore their own theories - from reincarnation, to ghost conversations, and the weigh of a dog's soul. 

She's giving a talk about her book at the University of Otago's 'Science and the Afterlife' festival in the few days, and tells us about the theories she's heard.
