This week, Dr Dominic Ford joins Dave Ansell to take on your questions about our universe. They reveal whether it's possible to live in outer space for years on end, if we can see the flames of the sun from here on Earth, discuss what dark matter is, and investigate what existed before the big bang! Plus, we find out why snakes aren't poisoned by their own venom and explore when the modern calendar was created.
