How does answer com know everything?

we get updated on everything if we don't we eventually find out.

sorry about the last answer yes it is a possible to know everything i am telling yall my uncle is VERY smart he knows everything i just go over there to play minecraft but when i ask him a quesion...

No human, regardless of intelligence, will ever know everything there is to know - it's impossible. If you think you know everything, then you are truly ignorant to that of which you don't know.

We don't, but what one one of us doesn't know another of us will. That's the power of the Wiki approach. They are omniscient.
