There may have been worse destinations for my journey through time – but I wouldn't get another chance to find out.

When I arrived at the end of the world, the only human beneath a glowing sky, heated by a sun that was far too close, I just managed to save myself by jumping out of the time machine onto a rock as the vehicle slowly sank into the magma. And now I stood here, watching as the burning world around me disappear into a sea of flames.

How long would it take for the flames to engulf this last island?
