Cosmic superclusters, the Universe’s largest structures, don’t actually exist

“The idea of a supercluster and the name for ours, “Laniakea,” will persist for a long time. But just because we named it doesn’t make it real. Billions of years from now, all the different components will simply be strewn farther and farther apart from one another, and in the farthest futures of our imaginings, they’ll disappear from our view and reach entirely.”

Galaxies don’t just exist in isolation in our Universe, but are often found bound together as a part of even grander structures. Our own Milky Way is bound in a galactic group (our local group), nearby are larger groups and galaxy clusters, and on still larger scales, cosmic superclusters appear to encompass as many as 100,000 individual galaxies. Yet it isn’t sufficient to simply see what appears to be a collection and draw an imaginary line around it. You can’t just give something a name and proclaim that it’s meaningful because you defined it. Instead, for a collection of objects in space, they need to be gravitationally bound together and connected. Thanks to dark energy, these superclusters aren’t.

Over billions of years, the galaxies in even our own Local Group will separate from the other clusters and groups nearby, and we’ll never wind up with a bound supercluster. Not here, and not anywhere in the Universe.

full offence I’m so tired of YA making girls end up with their childhood crush (who only recently even noticed them) rather than someone who actually suits/compliments their current ! day ! self !

IMAGINE: reader doesn’t want any kind of relationship with Carl but keeps casually trying to convince her.

You rode a skateboard to school when your mom couldn’t drive you, so Carl could find you anywhere you went with the very sight of a neon pink skateboard nearby. He jogged alongside you one morning as you looked on down the street calmly while he talked to you. “You like pizza? My family was gonna get some tonight if you wanna watch the game with us,” he hinted. “I don’t do football and I only like combination pizza,” you sighed. “We’ll get one of those. Maybe we can watch Liam’s dinosaur movies instead,” he persisted. “Maybe some other time. See you in algebra,” you answered as you rode off to the opposite end of the school where your friends were. He came to a stop and watched you walk inside the building. You were so cool to him, totally confident and tough; he liked it all.

He tapped your shoulder and nodded his head to the sleeping teacher in your lunch detention. “How much are you willing to bet me that I can hide all her stuff and draw a dick on her forehead without waking her in five minutes. Chucky and Val pushed it up to thirty-five,” he smirked. “How much are you askin’?” you asked him in reply. He turned to you with a smug look on his face as he looked you up and down. “I won’t date-” “Your skateboard,” he cut you off. Your lips parted a syou thought about it. “Deal,” you smirked. Well—that teacher bitch never woke up. He collected your skateboard after school, claiming it for himself with a Red Bull sticker in the middle of its backside. Now what were you gonna do? You couldn’t just walk, you lived too far. Maybe you could steal it back? Win a bet to get it back? You knew Carl, and things always had to be done in a sketchy fashion. 

You sighed as you knocked on his door the next afternoon and thought over this decision to simply ask for it back. Fiona Gallagher answered the door. “Can i help you?” she asked. “I’m Carl’s friend, Y/N. Is he here?” you asked her. She turned back toward her house and called out her brother’s name to which you heard him bolt from somewhere in the house to the door. “Hey,” he said coolly. You cocked a brow as you said hello back. “Look, I know you won it fair and square but that board is kinda my only ride at the moment,” you said hopefully. Carl hesitated before he looked over his shoulder. “You wanna come inside and get it?” he again insinuated. He seemed hopeful and you were hesitating. You smiled as you nodded, “I’d love to.”

You spent the next two hours having dinner at Carl’s house and hanging out with him and his family. Carl convinced you to go out with him as you were leaving, which you had to admit, was an opportunity long overdue.

Some Things I Concluded After Watching Chapter 8

1. Blake needs Sun. No, I’m not talking in a romantic sense (though I do like Black Sun), I’m talking in a motivational sense. Sun is persistent, and although that persistence can be irking at times, it does not wane. He won’t let her run away, and which is something she needs to stop doing if she is going to grow. Yes, Blake has developed a lot, but she still runs away from her problems, rather than facing them head-on. Sun can help put a stop to that.

2. Remember in chapter 4, when Qrow scoffed, “Luck”? He didn’t just say that because he was the one killing the Grimm. He said it because he knows that with him around, good luck isn’t exactly a thing. 

3. Qrow may have been with Summer when she died, and (if that’s true) blames himself.
