What if we had a separate “sense” organ to process magnetic waves around us similar to how we already perceive light, sound, touch, taste and smell? Yes, roses produce a fantastic fragrance but a rotten egg is far from being edible and we sense it. Similarly, it would’ve been fantastic if we could sense magnetic waves and learn how to find directions without using a compass just like we distinguish between the bad and good odour, pleasant and horrible sights and so on.
This can be food for thought if one has to pass time while travelling in a bus and the destination is yet to arrive in 5 hours. But, there is one thing which it reveals clearly. Our senses do not allow us to ‘gather’ all the information available around us. Some things are clearly missed and we can never know them because we have no sensory perceptions to let that information enter into our nervous system. There are some things that can never be known and the interesting part is – sometimes we don’t know what we don’t know.
Even our eyes have blind spots which do not allow the eyes to collect complete information about our surroundings. Our brain processes the images around these blind spots and assumes what could fit in that little leftover space to give us a ‘complete picture’. Even our eyes are incapable of producing an accurate copy of the physical world in front of us. No wonder these  human developed theories have limitations and even accurate, mathematically designed architectures fail as we ‘overlook’ many things which are sometimes in plain sight. It might not be because we don’t want to know something but it is because we don’t know what we don’t know. 
We fear the known unknowns but we don’t fear unknown unknowns. Maybe the unknown is processed as something ‘known’ by our brains and it is perceived as dangerous, thus leading to fear. Whatever one may perceive from what they read but this semantic wordplay certainly has the essence hidden in it.
