Have you ever thought, “Where the hell are we?” I don’t mean like when you are lost on a road trip, I mean, where the heck is Earth? Where, exactly, is this planet of ours within the wider world? We are in a solar system, a galaxy… the universe — The Universe! What is that? How big is it? Where does it go? Where is it? So many questions!
These are questions I’m sure many of us have asked during those times when we ponder our existence or the meaning of life, and even when we care so much about that little piece of our hair that isn’t quite sticking in the right spot.
But that’s the point of what I’m about to show you. We take life to seriously sometimes. We transform the smallest things into biggest things in the world, all in our own minds, and inflict so much anxiety and suffering on ourselves as a result.
The scale of the universe is almost beyond our imagination.
The universe keeps expanding (at 42.5 miles per second per megaparsec), and we constantly form new hypotheses about how it was created and what will happen next. Our farthest space probe from Earth, the Voyager 1, is traveling a million miles a day, and after nearly 40 years, has barely left our solar system. It was only late last month that scientists peered 50 million light-years away to find an extremely rare globular cluster, with far more mass than the Sun, which could birth stars and help explain how galaxies form. There are so many secrets waiting to be unlocked out there in the vastness of space.
