ELI5: How are we certain that the laws of physics are true for the WHOLE universe and not just our Earth/solar-system?

The ways in which we observe the rest of the universe (by telescopes, hadron colliders, etc.) are all done here on Earth, so how are we so sure these laws are so accurate for the entire universe?

I was reading Three Body Problem by Liu CiXin and a very good theory was presented. Turkey Theory, there is a barn full of turkeys, but one of them is very smart. He is science turkey. He noticed that every day at 1:00 pm the farmer would come out to feed all of them, so he made it into a law. We get fed every day at 1:00. Until thanksgiving day when the farmer came in and slaughtered them. 

It could be that the laws we know are subject to abrupt change in the future. What we see as a pattern, could just be a fluke.
