(Via Exploring our Matrix)
The above image makes the point that we can perceive only a tiny piece of it. And yet, what we perceive is actually illusion, since matter is mostly empty space. And the image doesn’t discuss dark matter and energy, which may make up the vast majority of substance in our universe.
It always stuns me to realize just how much our world has changed in the past two centuries or so. There was a time, not too long ago, when every human believed that our solar system was the entire cosmos. Even just a century ago many people believed that the Milky Way galaxy was the only galaxy that existed.
It’s humbling. And at the same time, it’s inspiring. So far, we are the only creatures we’ve encountered who are aware of how small they are. We’ve climbed to the point that we can just start to see how much farther we have to go.
