  I really, truly hope so Harrysimp710. There are going to be so many amazing, exotic worlds out there and I don’t think looking through a telescope is going to be good enough!
  
  According to our understanding of physics, we might not be able to travel faster than light, but maybe we can travel as fast as light? Then we’ll only have to wait about 4 years to travel to the nearest star.
