until further notice my brain is too chock full of galactic civil war era Star Wars

Also, I thought I’d do a post on why many Romani people openly refer to themselves as “Gypsy” instead of Romani.
So, in the United States, half of the people don’t even know what the actual terms for us are. Conversations usually go like this:
"Oh are you Italian or something?"
“No. Romani. A diaspora from India.”
“*exasperated sigh* Gypsy.”
“Omg! Can you read my palm?!”
So, a lot of us honestly just say Gypsy and move on. That doesn’t negate the fact that it’s a slur. So don’t come to me talking about how some Romani people use it therefore it can’t be oppressive. Gadje stop.

You are looking at the most precise gravity map ever made of a distant galaxy cluster. Using the map, astronomers have determined that the cluster is roughly 650,000 light-years across and contains enough matter to make 160 trillion suns.

The cluster, known as MCS J0416.1–2403, is located about 4 billion light-years away and consists of hundreds of galaxies all orbiting one another. Newton’s gravitational equations can tell you the mass of two objects orbiting one another, provided you already know the mass of one of them. However, because these galaxies are all so distant, there is no way for scientists to determine any of their individual masses.
But there is another way. Einstein’s theory of general relativity tells us that heavy objects warp the fabric of space-time around them. As light travels through these warped regions it will become distorted, and we see that as smeared out rings and arcs in our telescopes, an effect known as gravitational lensing. Using the Hubble space telescope, astronomers identified smudges in the light seen around MCS J0416.1–2403. These distortions are images of even more distant galaxies sitting behind the cluster; their light has been lensed by its enormous mass. By carefully determining just how much the light is smeared out, researchers can calculate the amount of matter sitting within the galaxy cluster.
The 160 trillion solar masses includes both visible matter and dark matter, which gives off no light but makes up the bulk of the cluster’s mass. By studying the dynamics of all the galaxies within the cluster, astronomers can better understand this mysterious substance. Researchers will also continue mapping the smeared out images to increase the precision of their mass calculations, learning about the cluster’s finer details to figure out its history and evolution.

GRS 1915 is an x-ray binary star system consisting of a star and a black-hole, and it’s got a heartbeat.
Well, a pulsating x-ray light that is, one pulse every 50 seconds.
And you’re like, “bro, what’s CAUSING this pulse?, that’s strange and I’m interested in science so I need to know..”
Turns out the black hole (spinning at 1,150 times per sec) is sucking in the matter from it’s companion star at 50% the speed of light though letting some of that energy escape. “The jet of materials being ejected is occasionally choked off by a hot wind blowing off the accretion disk. The wind deprives the jet of materials needed to sustain it. When the wind dies down, the jet returns (wiki)”, giving us the “pulse.”

did a quik doodle of tommy for my best freind,
ive only read snipets of young avengers so i dont know a whole lot about tommy but i def love him ;u;
also i wanted to draw him in his suite but i also wanted a jacket and ive been dying to draw tneishoes all day so sorry this is such a crao but its for my bestie so idc haha
A ghost calls and you fall in love with its voice again. Here. I made a place for us to sleep without nightmares. I don’t know what color your mouth is when you’re dreaming, but I bet it’s my favorite. You never wanted to be a train kissing the guardrails. You wanted to be in love, but no one notices the difference anymore. Come home. How am I supposed to know where my hands are without you to show me? I think they’re disappearing. I didn’t check, but I bet they are. Come home. Tell me I am where you left me. Tell me I’m not gone, too.
Y.Z, this won’t make any sense to you (via dimpleforyourthoughts)
