Since I'm a basic mathematics person I don't even try to get into numbers described here. I accept that such numbers exist. Some things we just don't have the science to fully know yet. Such as is the universe really expanding or is the matter within in actually compressing or shrinking? Who has the math or scientific knowledge to definitively answer that question?
Since I am a person of faith, some things I simply base on faith though even that faith contains elements of personal experience, logic, reason and trust in the dedicated research of others.
Since I am a person of insatiable curiosity, I wonder about a lot of this stuff. I have this 'list' of questions that is the only thing I want to take to heaven with me to get answers on the theory I won't recall all of them.
And because I am no Einstein and unable to wrap my mind around many concepts that were easy for him and others of his intellect, I just accept that I won't be able to personally verify this or that information in my lifetime.
(But just because I don't understand it is not sufficient in order for me to definitively say it isn't so.)
