Wherever we go exploring in the world around us, we find
mysteries. Our planet is covered by continents and oceans whose
origin we cannot explain. Our atmosphere is constantly stirred
by poorly understood disturbances that we call weather and climate.
The visible matter in the universe is outweighed by a much larger
quantity of dark invisible matter that we do not understand at all.
The origin of life is a total mystery, and so is the existence
of human consciousness.
Freeman Dyson, “How We Know”
