We’ve discovered and identified thousands of animal species, and we’ve unraveled the human genetic code. We’ve found thousands of new planets, stars, and galaxies, and we’ve observed a wide range of cosmic phenomena. We’ve explored the inside of the cell, atom, neuron, and electron. We’ve advanced much in our understanding of the world within and around us.
How much is there to know? How much do we know compared to all there is to know? Do we know 75% of what there is to know? 50%? 20%?
The observable universe we experience only represents 15% of the actual universe. Of the observable universe, we discover dozens of new species every year, and thousands of new behaviors among these species. We know next to nothing about how the human mind works and next to next to nothing about how the human body works.
The more we know, the more there is to know. How much do we know compared to all there is to know? How much are a trillion facts compared to an infinitude of knowledge?
