Supernovae are stellar explosions that are so powerful they briefly outshine entire galaxies, radiating as much energy as the Sun or any ordinary star is expected to emit over its entire life span

The Universe is so vast that it is estimated that a star explodes every second. In a galaxy the size of our Milky Way, a star will go supernova every 50 years on average.

A star can go supernova in one of two ways: 

Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. 

Type II supernova: star runs out of nuclear fuel and collapses under its own gravity.

Supernovae play a key role in distributing elements throughout the universe. When the star explodes, it shoots elements and debris into space. Many of the elements we find here on Earth, including life, are made in the core of stars. These elements travel on to form new stars, planets and everything else in the universe.

You are a villain famous for “killing” heroes. In reality, heroes come to you to fake their deaths.

When the sorcerer found the dragon, it was attacking a grape.

This was only possible because the dragon was not much larger than a grape itself, but she still had to do a double take to be sure the object it was fighting with such animosity was in fact inanimate.

She crouched so that her eyes were level with the top of the table and squinted at it. The dragon sank its tiny fangs into the grape’s skin and gave a great tug, succeeding only in throwing it and the grape into a backwards tumble. The tiny green reptile rolled to a stop with its whole body wrapped around the grape and shook its head ferociously, managing to pull its teeth out but also launching the grape across the table. It gave a mighty roar of anger (about as loud as a human clearing their throat) and stalked after it, tail swishing dangerously.

“Do you need help?” she offered.

The dragon froze mid-prowl and whipped its head around to look at her, looking so offended she almost apologized for asking.

“I mean, I could peel it for you, if that’s the problem.” She wasn’t sure it was getting the message. One could never tell how much human language these little creatures picked up by hanging around the magic labs. Some understood only such essentials as “scat!” or “oh fuck, that sure did just explode”, while others could hold entire conversations — if they deigned to interact.

This one looked like it was deciding whether she was worthy. Finally, it sniffed daintily and flicked its tail, scales clacking together. “Little monster is my prey, and you can’t have it. Found it first. Will devour it!”

“Oh, sure,” she agreed. “But you know it’s a grape, right?”

This was the wrong thing to say. It glared at her and then bounded away to the other end of the table, where it slithered up to the grape and pounced on it.

Grape and dragon promptly rolled off the edge of the table.

The sorcerer quickly went around to that side, alarmed that it would be stepped on. The labs were bustling with shoppers stopping by to watch demonstrations this time of day, and a small dragon wouldn’t be easily visible on the blue and green tiled floor.

“Horrible! Dirty!” The tiny dragon was screeching at the top of its lungs, holding onto its prey for dear life. It would have been hard to hear anyway, with all the noise of the labs, but with the sorcerer’s diminished hearing it took several seconds to locate the screaming creature.

She scanned the pattern of the tiles for it and sighed. “Oh, hold on, we mopped this morning.” She cupped her hands around it and deposited it into her skirt pocket, an indignity the dragon endured only with more screaming.

“An outrage! Put me down!”

“Shh,” she advised. Lab workers were strongly discouraged from bringing creatures into the back rooms, which was where she was heading, picking her way through the crowded front lab.

“Fuck pockets!” her pocket responded.

“Oh, you can curse. Wonderful.”

The dragon seemed to take this as an actual compliment. “Am multitalented. Can also compose poetry.”

“Really? Can I hear some?”

“No. For dragon ears only.” It sounded viciously pleased to hold this over her head. The bulge in her pocket rearranged itself, and she thought it might be trying to gnaw on the grape.

She felt herself smiling even as she tried to squash her mouth into a straight line. She liked this little bad-tempered thing, even though its spiky feet were digging into her thigh.

In the much quieter kitchen of the back rooms behind the lab, she transferred the wriggling, scaly handful from her pocket to the table. The dragon hissed out a few more insults as it got up and straightened itself out, but its jaw fell open when it finally took in its surroundings. She’d set it down next to the fruit bowl.

“There you go. Food mountain.”

The dragon’s shock didn’t last long. Abandoning the grape, it scraped and scrabbled its way up the side of the bowl and from there onto an apple, its claws leaving tiny puncture marks as it hiked to the top of the arrangement. “Food mountain!” It repeated, its gleeful crowing much clearer and almost sing-song without having to compete with the noise of the crowd.

She watched it turn in a circle, surveying the feast. “But… cannot eat it all,” it observed after a while, crestfallen. “Human-sized. Big shame.”

“Don’t you have nest-mates who can help you with it?” she asked. She had assumed not, from the way it had apparently been foraging for food on its own, but she needed to be sure she’d found a loner.

“No nest. No mates. No nest-mates. You’re rude.” It flopped down ungracefully, wings spread out flat on the apple like it was trying to hug the entire much-larger fruit.

She gave it a moment to be dramatic, and then offered it the grape, minus the peel. “You seem to have a good grasp on human-speak.”

It grabbed the grape without so much as a thank you. “Yes. Have composed poetry in both Dragonese and Humanese. Not for humans to hear, though.” Bragging cheered it up a little.

“You mentioned. I can’t hear very well, anyway.” She pulled up a stool and sat down. “Actually, I’ve been looking for a helper.”

“An assistant,” it said, apparently showing off its Humanese. “An attendant. An aid.”

She watched it bury its snout in the grape, juice dribbling down onto the apple it sat on. “Yes. A hearing aid. How would you feel about having a job?”

It smiled craftily. “Would feel positively, if job comes with chocolate chips.”

“It could,” she said, grinning. She had some friends who employed bird-sized dragons as messengers, but this was the first time she’d heard of one negotiating its salary for itself. “It certainly could. What’s your name?”

“Peep,” said Peep. “It is self-explanatory.”

“Don’t worry, I got it.”

Peep expressed its doubt that humans ever got anything, but she thought the tiny, prickly creature might be warming up to her.

boston gothic

- there is no grid system in boston. every street is a circle. you miss your turn and try to double back, but the asphalt is giving way to cobblestone. you can hear muskets just ahead.

- boston common always closes at 9pm. it locks from the inside.

- you walk out of mike’s pastry in the north end and the streets are deserted. there’s a rumbling beneath your feet. it smells like molasses.

- every time you crane your head to peek down the dark subway tunnel for the train, you can see two bright pinpricks of light in the distance. they’ve been there for 30 years, watching. you look away and try not to breathe.

- they’re always trying to fill the pot holes and the cracks in the sidewalks. it’s from the ice, they say. come morning, the holes always return. bigger. deeper.

- the next train will arrive in 5 minutes. days have passed; winter is setting in. the next train will arrive in 5 minutes.

- you arrive at logan airport and it’s empty. the intercom crackles, “this is the final boarding call.” no flight is specified. it’s time to go.

- the red line train pulls up, empty. you get on and it comes to a sudden halt in the tunnel. the lights go off. you hear the muffled sounds of ‘sweet caroline’ in the distance. it’s getting closer.

- the citgo sign looms above the brownstones. no matter how far you walk, it is always there. 

- you hear rustling. it’s just the turkeys, you say. you hear screams echo in harvard square. it’s just the turkeys.

“Erik, Dear, Tourists Are Making A Buzz Of Your Giant Cat Sunbathing On The Roof Of Your Penthouse,

“Erik, dear, tourists are making a buzz of your giant cat sunbathing on the roof of your penthouse, they can see him all the way from the Rockefeller observation deck.” Emma clicks on another Youtube video. 

Oh, they were the ones who waved at me!  Charles chirps. 

“…not only abnormally big, but also telepathic. You better not let U.S. government knows this, they were debating if they should prepare for Giant Alien Cat Invasion of Earth.” Because Charles is a global super star now and so likable, there were some movie invitations, even. 

Erik stretches and buries his face into Charles’ fur, “Let’s take a walk and make everyone wish Giant Alien Cat Invasion will happen now.”

The story about how Erik have a cat Charles, who grew into the biggest cat in the world. Inspired by this

Title: Collard: Chapter 12: Eyes Wide Open Rating: PG Genre: AU, master/slave (though we’ve kinda left that behind at this point) Pairing: Roy/Ed Warnings: blood, injuries

“We’re still getting reports from Yousewell that are … somewhat suspect,” Grumman said as he moved his bishop to block the path of Roy’s rook. “But Central doesn’t seem concerned. I don’t think they’ve even read the last two memos I sent.”

Roy took his time considering the board. “The last unit they sent out that way never made it.”

“Yes, and we know how that worked out.”
