Objective reality is not different for everybody. What's unique to each observer is their own (subjective) perception.
Objective reality is not dependant on the observations of an ignorant life form that can't even observe or directly measure 99.999...% of their observable patch of universe. A black hole 28 billion light years away (which has no causal relationship with our observable bubble) is not even slightly affected by the musings of a flea.
Your subjective experience of reality has to be a subset of objective reality, that is to say, whatever you experience has a foundation in something greater, consisting of processes and states of being that we don't yet, or cannot understand.
Humans did not know about germs, bacteria, spores, etc, for a very long time. But our ignorance of these micro-organisms did nothing to protect us from them. The dinosaurs presumably knew nothing of asteroids, and their ignorance did not protect them. Our planet 'knows' nothing of gravity or mathematics, yet is bound by them.
Objective truths apply to you even if you are ignorant of them, even if your brain is incapable of acknowledging them, even if you have no brain.
