“We must admit that we do not know everything about our world. What we know is not all that we can learn. We do not even know how much we do not know and how huge the difference between what we know and what we do not know is. We do not understand quantum mechanics in a real sense. We do not realize what gravitation is. We do not know if there is only one universe that we think originated from a Big Bang or if there are many other universes. We do not know what dark matter is, and we do not know what dark energy is, nor do we exactly understand these phenomena.”
― Dejan Stojanovic, ABSOLUTE
