Dear Tumblrverse,

Before the explanation part of this post, I need to say this so it will be in posts that are shortened by a reblog: More than anything I ask that you reblog this post so that kind millionaires more people will see it and more support can be…

"There are two great mysteries that overshadow all other mysteries in science. One is the origin of the universe. That’s my day job. However, there is also the other great mystery of inner space. And that is what sits on your shoulders, which believe it or not, is the most complex object in the known universe. But the brain only uses 20 watts of power. It would require a nuclear power plant to energise a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that’s a compliment."

"We seem to crave privilege, merited not by our work, but by our birth, by the mere fact that, say, we are humans and born on Earth. We might call it the anthropocentric—the “human-centered”—conceit. This conceit is brought close to culmination in the notion that we are created in God’s image: The Creator and Ruler of the entire Universe looks just like me. My, what a coincidence. How convenient and satisfying! The sixth-century-B.C. Greek philosopher Xenophanes understood the arrogance if this perspective:
The Ethiopians make their gods black and snub-nosed; the Thracians say theirs have blue eyes and red hair… Yes, and if oxen and horses or lions had hands, and could paint with their hands, and produce works of art as men do, horses would paint the forms of the gods like horses, and oxen like oxen…"

"The reason we struggle with insecurity is because we compare our behind-the-scenes with everyone else’s highlight reel."
