‘We may not even be the principle stuff of the universe. That’s how insignificant we are. Okay we have learned the universe has this stuff that has gravity but doesn’t otherwise interact with matter as we know it. It doesn’t shine, it doesn’t reflect, it doesn’t block, it’s dark. It’s called dark matter. (4% of the universe can be seen or detected) 96% of the universe is not us, it’s something else.’
-Neil deGresse Tyson
