  Do you mean if we travel at the speed of light into space would we look back at Earth and see it as it was 100 years ago? This wouldn’t be the case as we already have air craft that travels at the speed of sound.
  
  If we traveled at the speed of light for 600 trillion miles into space and looked back at Earth, we’d be looking at it 100 years ago, as that’s how long it would take to travel that distance. When we look at stars, a lot of them have probably died, as it’s taken that long for the light to reach us.
  
  Let me know if this doesn’t answer your question!
