Auckland University Professor of Physics Richard Easther takes us on a journey around the universe, exploring Mars and Pluto, skimming past the huge black hole in the Milky Way and ending where time began.
Professor Richard Easther explains when people might get to the fourth planet from the Sun, the dangers of staying for any length of time, and whether the planet would look anything like The Martian.
Formerly a planet, now a dwarf planet, Pluto has massive ice mountains and a huge moon, Charon. The Horizons probe took 10 years to arrive, but a manned mission would take a new type of rocket - presumably nuclear powered.
Richard Easther wants to get close - but not too close - to the black hole at the centre of the Milky Way which has four million times the mass of the Sun. He discusses the science-fiction forms of transport which could get people there, and what there is to see at the site.
The Big Bang, which started the universe as we know it, happened in every point in space. So to get to Richard Easther's personal favourite destination, all you have to do stay where you are and dial back time. When you arrive, presumably in a Tardis, whatever you do, don't open the door.
