Do Raptors Fear the Unknown?

Raptors are a evil thing, but do they fear that they don't understand?

Take the scene in Jurassic Park where they killed the hunter. They hid in the bushes until he was in a range that the raptors seemed to take as "uncomfortable", at which point they ripped his throat out. Or some other appendage. Not that it....anyway.

My point is that can we use this fear of the unknown against them? Can we wield the power of astrophysics and astronomical travel against them?!

Nasa, get on this.
