When I read articles that discuss the vastness of the cosmos and the trillions upon trillions of stars that inhabit our universe, and the likelihood that there are perhaps billions of inhabited planets out there teeming with life, the emotion I feel most is not awe, but a deep sadness for all that we’ll never know or understand about the universe. Many of these galaxies are tens of billions of light years away, so unless there’s some pretty impressive loopholes in the laws of physics as we understand them today, we as a species will never know what lies beyond the tiniest fraction of our little corner of the universe.

And that’s depressing.
