Space, is big. Really big. You just won’t believe how vastly hugely mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to space.
Scientists decided last week, thanks to the help of this fantastic picture (even better if you get one with higher resolution), that approximately 96% of the universe is Dark Matter and Dark Energy. You see, this picture is looking at about a 10 billion year span of time. For reference, each of those little bits of light is not a star, but rather, a galaxy containing millions upon millions of stars. And by looking at the stuff in the picture that’s oh-golly-gosh really old, NASA saw different things than when they looked at the stuff that’s, well, middle aged in galactic terms.
So, it’s definitely there, but what is it? No clue. It works as some sort of anti-gravity, taking up the spaces between objects that have gotten so far apart their gravity isn’t affecting them anymore. But, the while the opposite of love isn’t hate but rather apathy, this is not true for stars. When they get far enough apart, they’re not content to just continue drifting aimlessly away from one another. Oh no, indeed, they invoke the Dark Matter and Dark Energy and send their frigid former star-friend flying away at dizzying speeds.
Scientists will just tell you the universe is expanding faster, but that’s no fun, now is it?
Incidentally, Happy Thanksgiving all. Mr. Thursday, for one, is looking forward to the mashed potatoes, and is thankful for the Ultra Deep Field, the daily insanity of the MLB off-season, Aldaris Porteris, and you, interweb.
