A quick thought about Astronomy.
This is a serious post. If you don't know how to add to a discussion or say anything except for spam, please just ignore this post.
We are on a [i]very[/i] small planet, which rotates about its axis, an axis which moves (look up:precession), while rotating about our star, while rotating about the middle of the Galaxy, in a galaxy which moves about other galaxies, galaxies which are gravitationally bound in a cluster, which moves about all the other clusters in the universe; all the while gravity bends light, light takes time to travel to us, and the expansion of space has been accelerating for the past 5 billion years.
We have absolutely horrible vision of the universe. Countless calculations have to be made to correct for error when observing space. [b]What If we're missing something?[/b]

This video explains the concept of "super clusters" and how scientists group galaxies to map this out. What's absolutely amazing to me, is when they go into the 3d model, and every single one of the bubbles is representative of a galaxy (with 100's of millions of stars). And that is all just in our super cluster, Laniakea which is about 1 billion light years across. Everything we've ever known, it's literally just a speck inside one of those bubbles. And then we also have to consider that Laniakea isn't nearly everything in the universe. The universe is an estimated ~93 billion light years in diameter. This sort of scale is incredibly humbling.
