Could it be possible to create a machine that was made entirely up of light or energy? I mean let's say I wanted to travel to the nearest star and it's solar system and the star was 4.5 light year away. Now it would take me 4.5 light years to get there. Now what if someone manipulated light like they manipulate matter and created some sort of robotic space traveling light machine that traveled there and came back 9 years later with clear images of the star its planets.
