Humanity has long dreamed of travelling and settling among the stars. The fact is that like any other star, the Sun, will one day succumb to gravity and run out of its primary fuel, hydrogen. When this happens, life on earth will become impossible, as the sun envelops our planet. Understandably then, many have considered the possibility of colonising planets beyond our solar system in order to ensure the survival of ‘Earthians’ (my moniker for humans born on planet Earth) beyond the fixed lifetime of our sun.Zoom or Doom imagines such a journey but on a far grander scale — expanding beyond our galaxy. Marx Afaro Zytan, an oddball who appears nervous while relaxed but serene when nervous, is a ruthless man and an inhabitant of planet Zist. The book follows his story, which revolves around the revolutionary scientific discovery of a special type of fuel system that can transform matter into energy. This not only enables the possibility of light-speed travel for space-ships, but intergalactic travel and even time travel.
