Not in science. A fact is an observation or evidence that has been repeatedly observed to be true. It doesn't mean always true or only true.
The problem is when existing theories compete. OR more precisely points within large theories compete. Take relativity for instance, gravitational waves help explain the big bang but not all observations support the big bang model. But gravitational waves are considered fact for the purpose of the theory even though it has never been directly observed because it can be explained in mathematical computations that explain observations.
So what happens when we actually detect them for real and they operate slightly different than we think? Does this new observation or fact get pushed to the front of the line or is it buried because the fact engine hasn't updated yet or the wikipedia article it is referencing is in a mod battle. How about if something else is found to explain the theory concerning gravitational waves but lives in the same limbo as gravitational waves in which it hasn't been directly observed but can explain observations with math also.
It reminds me in the 80's when (and I forget who) some doctor was claiming most stomach ulcers were the result of bacteria. Turns out that is a fact but he was originally ridiculed because the fact at the time was that no one believed that bacteria could survive in the stomach's acidic environment longer than it takes to pass through it. Now the fact is that it's cheaper to just giving a couple antibiotics and seeing if the ulcer disappears than to test if the ulcer is bacteria related or other. But it was indisputable at one time, then someone disputed it and now it is indisputable again. Facts change.
