Which is in contrast to objective information that can be proved, irrespective of the observer

I'd be very interested as to what 'objective information' there is. As near as I can tell, all info is subjective. Everything is filtered through the senses & interpreted by the mind. Because of this, we don't even see 'Now' but rather see a moment in time that is really in the past by a few hundredths of a second or more.

Not being picky here, just curious as to why the view that you can never know about others wouldn't also be applied to the whole of Reality.
