What does Occam's razor say about a contradiction?

If two things that are observably exactly the same behave differently, then what should one conclude is the simplest explanation?

If you look in a telescope for a year, and notice that an apparently free-floating star out in the galaxy with no neighbors is taking a sharply curved path and everything else in the sky is going basically straight, you have two choices: 1) either something you can't see yet is there and acting on the star, 2) conservation of momentum, and the law of equal and opposite reactions need to be thrown out because they're wrong, and we need to start from scratch with physics.

Which of those two would Occam say is more likely?
