I like to think this is what Miyazaki characters do when they aren’t filming amazing movies!

Dark Matter, Dark Energy And The Shadow Universe
Let’s start with a very important distinction. Dark Matter and Dark Energy have nothing (as far as we know) to do with each other. The only thing they have in common is that evocative adjective “dark,” which, for astrophysicists, simply means we can see an effect but we can’t see the cause.
Astronomers see things moving when they look out at the universe. Using the laws of physics, they try to infer what drives those motions. There are only four known forces in the universe: gravity, electromagnetism and two forms of nuclear force. These are the only ways we know for stuff to push (or pull) other stuff.
On astronomical scales, gravity is the main actor. Ever since Newton and Einstein we have known how to relate gravity to the quantities of matter and energy present in any given environment.
Over the last few decades something remarkable has been observed. The matter and energy we can see is moving too fast to be driven by its own gravitational force. Based purely on the motions of galaxies, astronomers have been forced to infer the presence of matter that’s undetectable with light-gathering telescopes.
Likewise, based on the motions of the universe as a whole (and its structure), astronomers have been forced to infer the presence of energy that cannot be directly detected.
Dark Matter is a form of mass (some new kind of particle) that simply does not emit light. Dark Energy is some kind of cosmos-filling field capable of doing work that is also invisible. But Dark Matter and Dark Energy are very different.
THIS IS A FRIDGE.
AND THE GREEN STUFF IS GEL AND YOU JUST SHOVE YOUR FOOD IN IT AND IT KEEPS IT COLD.
I WILL EAT OUT OF THIS ONE DAY.
Can I just shove my whole body in that
:O
what
I WILL PRETEND TO BE HAN SOLO.
I must be old, because this is freaking me out.
I WOULD BE HAN SOLO TOO
OH MY GOD HAN SOLO YOU WOULD PLAY HAN SOLO YOU ARE THE BEST PERSON ON EARTH :’D
