More than just a novelty, a very rare phenomenon found with the Hubble Space Telescope can offer insight into dark matter, dark energy, the nature of distant galaxies, and even the curvature of the Universe.
I read stuff like this, and it makes me want to go back to school and research stuff. Not that I know anything at all about dark matter and the nature of the Universe. But this is just cool. I don’t get nearly enough of that at work.
It makes me feel very small, though, thinking about distant galaxies. It reminds us that the Universe is kinda big, and we’re relatively pretty friggin' tiny.
