User blog comment:FairyTailFan7/Sting's Attacks Are Light Speed?/@comment-26715029-20150820131706/@comment-1153699-20150820165340

Hiro is not a scientist. He's a Mangaka. I seriously doubt he took the Laws of Physics / Science into account when he drew Natsu dodging Sting's Laser.

The Light Natsu saw from the Laser is probably Light Speed but the speed the Laser itself actually moves at is not Light Speed imo. It's Magic. Magical Lasers =/= Real Life Lasers. Just like how Azir's Sand Magic isn't normal Sand and Jura's Rocks are waaaay more durable than real life / normal ones.

In real life, Shadows can't hurt you. But in FT, they can. Why? Because Magic. It's possible for Lasers to not move anywhere near the Speed of Light. Why? Because Magic. It's really that simple with FT..
