Quote by Salman Ahmed Shaikh

“For validation of knowledge about something, seeing something is not necessary. We use inference to know about things we have not seen, but which nevertheless are considered as true by inference. We would infer that someone put book on table if it was lying in cupboard when we last saw it. If we see an infant crying in a stroller in park and is unattended, we would immediately search for the parent or attendant who would have accompanied the infant to this place. Inference can be used to derive valid knowledge about unseen concepts whose physical manifestations can however be observed like gravity, for instance. We know that dark energy and dark matter, detectable only because of their effect on the visible matter around them, make up most of the universe. We knew black holes exist even before we observed them through a visible image in 2019.”
