the fermi paradox is so funny to me because people make it out to be some kind of cosmically horrifying unexplainable mystery but it's literally so easily solved by the speed of light. like everything in the universe is very far apart and there is a hard limit on how fast something can travel. like we've been sending out signals into space looking for alien life for what, 50 years? because of the speed of light, that means that these signals have traveled for, at most, 50 light years (shocking). if i go on space engine to check roughly how many known star systems exist within a 50 ly radius around earth, we get a grand total of: 776. even if we add in procedurally generated ones to get an estimate that accounts for star systems we don't know about then our total goes up to 3,407. our current estimations for the number of stars in the milky way alone is around 100 BILLION. our messages have only reached like 0.000003% of the total number of stars in our galaxy alone. and even if there are any stars with life within that radius, who says they would be able to receive these messages? single-celled life first evolved ~4,000 million years ago while multicellular life only came to be around ~1,600 mya. primates only evolved within the last 100 million years. we've only been able to receive signals for a few centuries. and if these aliens did receive our signals and were able to send them back, it would still take a while for those signals to then get back to us. if they were 25 ly away (a radius that contains 122 known star systems, btw) then it would take 25 years for the signal to get there and then another 25 years for it to come back. and this isn't even getting into the fact that these signals would become less intense the further they go due to the way light works. either way it's just so fucking funny to me that people think that "powerful aliens KILLED them ALL and they're coming for US NEXT" is anywhere near the most plausible explanation

💗💗💗

You didn't want to be taking organic chemistry. Nobody in that class did--not even the chemistry majors. But as finals season rolled around, you found yourself spending extra time to make sure that it would at least be worth your while. Needless to say, not everybody shared the same drive.

As the clock hit 8:49am on the last class before the exam, everybody started shoving their laptops away despite the professor's continuing drone. To your right there was an extra loud snap! as the student beside you--an auburn-haired girl you'd never seen before--shut the screen with finality. You shot her a glare, gently closing your notebook as people began to trickle out.

"You're smart, right?"

You angled your face towards the sound, assuming somebody was having a side conversation close by. Instead, you found yourself face to face with striking green eyes leaning to reach your line of sight.

"Hi. Yeah, you. You're using an actual notebook and have all the fancy pens and shit, so...are you smart?"

Your eyebrows drew together slightly as you shrugged with one shoulder. "I try, I guess. Um...why?"

One corner of the girl's mouth picked up. "I don't know if you've noticed, but I've literally never been to this class before. My grade sucks. But I really don't want to retake this shit. Do you think you could help me?"

You stared at her incredulously, mentally calculating the equation of audacity and arrogance it must take to expect a complete stranger to help despite a clear lack of effort.

You opened your mouth slightly to say some variation of hell fucking no, who do you think you are anyways?, maybe you should have considered that before skipping literally every other class meeting when she stuck out her hand. "I'm Ellie, by the way. I'll pay you for helping me." When you hesitated to shake it, she added a "please".

You rolled your eyes, shaking the girl--Ellie's--hand with slightly too much force. "Fine. Whatever. Give me your number." You slid your phone across the table, already open to the contacts app, and watched as she typed.

"You're a lifesaver! Thank you..." she asked, pausing for your name. You gave it. "Thank you."

💗💗💗

Getting back to your dorm and settling into bed for a nap, you briefly texted the number now in your phone as "Ellie" with the last name "Wehavechemistry".

hey

Almost immediately, three dots popped up.

hey there. do you like my contact? lmao

i mean, we do have chemistry together. so like...sure?

no no no. i meant like...we have chemistry. wink wink nudge nudge. and my last name starts with a w so it's funny. do you get it?

...

it's funny.

yeah yeah sure. very funny. hahaha. anyways.

when did you want to come over? i'm free all weekend, and the final's monday. sooooo

oh shit

didn't realize the final was monday

ummmmmmmm how does tomorrow at 8pm work? do you have a roommate or something we need to accommodate for?

no, no roommate. tomorrow at 8pm works fine for me. see you then, ellie.

:)

Turns out, texting with Ellie wasn't all that insufferable. She was friendlier than you expected, and every time you put your phone down to try and fall asleep you found your heart beating too fast at every notification to actually put it down.

Instead, you kept the conversation going until 8pm the next day rolled around, when instead of a text you got three loud raps at the door.

Opening it up, you saw Ellie in the same hoodie as yesterday. This time, her hair was slightly damp and she smelled like...old spice and something pungent and earthy. Did she shower already?

"Hey," you said, suddenly feeling awkward and over dressed in your jean shorts and crop top, hair still done from that afternoon. "You can come in."

Ellie grinned at you as she slid in the door. "We have a semester of schoolwork to cover. Hope you're prepared for a long night," she said.

"Trust me, I am. Did you bring anything?" You asked, looking for a bag as she climbed on to your bed.

"Nope. Not school stuff, anyways." Curious, you tossed your notebook towards her and watched as she pulled a pre-rolled joint and lighter from her hoodie pocket. "I'm assuming you don't smoke since you're like, a nerd, but do you mind if I do?"

You shook your head, dropping your jaw in false offense. "How lame do you think I am? Just because I actually go to class doesn't mean I'm a nerd."

Ellie shot you a disbelieving look, but handed you the joint anyways as you joined her on the bed. "Here, have the first hit. As a thank you for helping me out."

She lit it for you as you inhaled, passing her the weed and opening your notebook. "If this keeps you from retaining information that's not my fault. Just saying."

"Trust me, I'm so alert right now it's crazy. All of tonight is gonna be stuck in my memory for a while."

💗💗💗

The room gradually grew darker, lit only by your adjusting lamp and the last smoldering ashes of the joint as you reached halfway through the notebook.

You breathed heavily through your nose, looking at Ellie seriously. "It's so late. We're not going to finish this tonight."

As she looked up at you, you suddenly noticed how much closer you two had moved over the course of the night. Had your thighs been touching the whole time? Has her breath always been so close it's hitting your cheek? Why did she have to smell so good?

Your own breath caught in your throat as she leaned even closer to you, placing a hand so close to your leg you could feel the fabric of her sweatshirt against her bare thigh. Almost imperceptibly, her gaze flickered down to your chest, now rapidly rising and falling.

"How set do you think I am for this stupid final?" Ellie asked seriously, a rasp in her voice either from smoke or the lowered pitch.

"You picked up on everything really well, so at least the first half I think you'll do fine."

She grabbed your left hand in both of hers, causing your breath to catch again. Her eyes flickered down again, this time lingering longer. Following her gaze, you noticed the top of your bra peeking out.

"Sorry," you said, quickly adjusting your shirt to cover it as heat spread through your body.

"No, no, you're fine. Sorry for looking," she said. You looked at her face, watching as her eyes seemed to trace the shape of your shoulders and the line of your throat.

The air thickened with tension, but you found yourself not wanting Ellie to leave yet. "So, why did you take this class anyways? If you didn't want to go?"

Finally, she met your eyes. "I need a chemistry for my major. Astronomy. I thought I would like this one, but didn't realize it was a fucking 8am when I signed up. By the time I realized I wasn't going to make it up that early it was too late to drop." She shrugged. "What about you? Big chemistry fan?"

You snorted. "Not really, but I also needed a chemistry for my major. I like the 8ams, it lets me have afternoons free to sleep. That's why I don't have a roommate--medical accommodations for fatigue or whatever." She nodded along, genuinely listening.

"Well, hopefully I don't have to retake this class. Next time there probably won't be a pretty girl willing to help me out."

You smiled at her, breathing sharply out of your nose in a laugh. "We'll see what we can do."

A beat of silence washed over you before Ellie pointed towards the pride flag on your wall with her chin. "So...are you..." She began, causing you to laugh full out this time.

"Yeah. Obviously, I'd hope, but if you're feminine people tend to assume otherwise I guess." You smiled and looked at her. "Are you?"

Ellie placed a hand on her chest. "I'm hurt you had to ask. I've been trying to flirt with you since I got your number, babe."

Oh.

"Oh."

She leaned back a little. "I can cut it out, if you want. I couldn't tell if you were into it or not."

Without giving her time to continue doubting, you sprung forward and attached your lips to hers. Threading your fingers in her hair and breathing in as you pulled back.

"So...you are into it?"

"I'm a little dense, Ellie. Don't let the color-coded notes fool you. But yes. Now that I know...I'm into it."

She smiled at you with one side of her mouth again, this time leaning forward to kiss you first. Lips opening slightly, you felt her body around yours as her hands found the bed and pushed you on to your back.

Ellie pushed her tongue gently into your mouth, settling between your legs as they fell open. As you felt her weight between your hips, you groaned a little.

Whining a little as she pulled away, your eyes fluttered shut as Ellie threaded her fingers through the hair by your ear. "Is this supposed to be my payment?" you asked, leaning into her touch.

"Shut up," she said playfully, leaning in to kiss you again. This time it was more forceful, teeth bumping against teeth as your tongues chased each other. Too focused on the overwhelming sensation of Ellie's mouth on your own, you broke the kiss to moan in surprise when you felt her knee push against your core.

Using the opportunity to trail her mouth down your cheek, to your jaw, to your neck, Ellie asked "is this okay, baby?" between kisses. You nodded before remembering she couldn't see you, instead responding with a slightly choked "yes."

In response, her lips attached right behind your ear as her teeth sunk into you and she began to suck. You groaned, bucking your hips against her knee. Kindly, she began to push it back into you, laughing into your neck as you continued whimpering.

"What?" you asked. "Why are you laughing?"

Ellie pulled away from the spot she had been working into your collarbone, meeting your eyes. "You're just so pretty. Can't believe I have you falling apart for me and I've barely touched you."

Your mouth fell open at her words, groaning. Ellie's mouth found yours again, her hands reaching for your tits over your shirt. "Can't blame me for looking at these," she said between kisses, "You look so good in this shirt."

"Take it off, then," you said. You sounded braver than you felt, your stomach doing absolute flips as the girl over you quickly complied to reveal your lacy nude bra.

"I like this," she said softly. "I want it off, though. Is that okay, pretty?" You nodded. The bra was nothing special--just comfy and the right color. If Ellie liked it, though, it was now one of your favorites.

Her mouth moved down your chin and neck to attach to your left nipple, bringing a hand to your opposite hip as she sucked and licked lightly. Your hips continued to buck against her knee, which was now stationary as you essentially rode her thigh.

Chuckling a little, Ellie looked up at you and began unbuttoning your shorts. "Knew you'd be needy. What kind of thoughts are you hiding from me?" she asked, pulling off your bottoms and panties in one go when you lifted your hips to help.

You smiled a little watching her eyes attach themselves to the spot between your legs. "What can I say?" you said. "Maybe I'm a little slutty if the right girl has me under her."

This seemed to light something in Ellie, who watched your face as she brought your face down to your pussy. Close enough to feel her breath, her eyes gleamed as she moved away from your hips chasing her.

"Please," you asked, voice breaking. "Please, Ellie."

"Guess you are a slut, huh? Begging for me already." Whatever response you had was cut off by a screaming moan as her mouth attached itself to you, immediately lapping at your clit before interspersing it with longer licks. Your legs shut around her face as your hands grabbed into her hair, pulling a little as you noticed the groan she made at the pressure.

"That feels so good, Ellie." Her motions sped up at this, and you hurriedly repeated the phrase as she focused more attention on your clit. Feeling everything tighten, you wrapped your ankles around her back as your hips lifted almost completely off the bed. Still attached to you, Ellie fully moaned as you pulled her hair and came over her face.

Whimpering softly as she pulled away, you audibly groaned when she looked up at you and wiped her chin with the back of her hand. "You did so good, baby. Do you have another one in you?"

You quickly nodded, feeling words escape you. All you wanted was for her to say you did good again.

Ellie leaned into you, placing her head into the crook of your neck as her fingers ghosted lightly over your hips, stomach, and thighs. Finally, you felt them dip into the pool of wet that had collected in your cunt. Spreading the mix of saliva, cum, and arousal up to your clit and around your hole, she slowly pushed a slender finger into you. Your back arched off the bed when she began pumping it in and out, chuckling against your neck.

"Such a pretty girl. You're doing so good," she whispered. Your moans grew louder at her words and she pushed another finger in. "Good girl," she breathed, kissing your neck and jaw as she worked into you.

"Ellie," you gasped. "Ellie, please."

"What, baby?"

"Please, Ellie, please. Wanna cum."

You felt her lips quirk up against your collarbone as she added a thumb to your clit and a curl to her fingers. Quicker than you'd ever been able to get there yourself, you felt the tightening of your gut. She swallowed your moans with a sloppy kiss, gently catching your bottom lip between her teeth before soothing it with her tongue. She used her other hand to hold on to your hair at the scalp as you writhed, second orgasm shuddering through your body.

"Good girl," she said as she worked you through it. Sitting up, she wiped her fingers on your thighs before moving up up to let you rest your head on her chest. "You did so good, baby. My smart, pretty, good girl."

You whimpered a little, not prepared to speak just yet. Ellie seemed to understand and didn't push you, holding you and playing with your hair until you leaned back to smile at her.

"That was good. Thank you," you told her, leaning in for a kiss that tasted of your sweat and pussy.

Ellie broke away, moving the hand wrapped around your waist to grab something out of your back pocket. She placed it on your bare chest, tucking it between your tits.

"What do I look like, a prostitute?" you asked. "Much love to them, but..."

Ellie raised her eyebrows. "I mean, you fuck like a professional, but this is for helping me study."

You grabbed the bill and pushed it back into her pocket. "Save it for next time. We need to finish that notebook if you want to actually pass this class."

Ellie kissed the top of your head. "How does tomorrow work?"

A/N this is basically a self insert...my bad. tried to make it as inclusive to different readers as possible. let me know if there's anything I can improve on!! <3

Sinking…

Lately, I've been struggling with everything. My mom's dementia is advancing, I’m facing financial difficulties, and I'm overwhelmed with college work as I prepare to graduate soon. This makes it challenging for me to focus on the Cosmic Funnies store and create new comics. I'm currently working on a new collection for the back-to-school season, including iOS icons, but my chronic fatigue and depression often make it hard to function. I hope you all understand when I don't post new content. I promise to update you with new posts as soon as I can. Thank you for your patience and support.

got around an hour in of studying for wednesday’s quiz; must go to bed now as i have a 10:00 am class i’ve got to be on time for for once

writing sci-fi is actually a trap to make goofy trans women (me) do complex math. it's all mech pilots and sultry voiced AI until you start chasing a specific visual for your setting, and now you're trying to figure out if spinning a gas giant fast enough can counteract it's internal pressure, and raise the maximum size before it starts stellar fusion.

i just wanted the visual of spaceships flying through dense gas clouds. how did we get here

Boy

Are you the Planck Era?

Because unfortunately you are hot and dense as all get out

[minmin-vs-physics]

[5/8/24] my monday early start dreams were once again crushed because i went stargazing w my friends last night. (guess which photo i took. yes, they were both at the same place.)

fun fact: i came into uni thinking id do astronomy or astrophysics. i have taken zero astro classes. (untrue: i sat in on one astro lecture and immediately dropped the class)

kinda funny what you think you'd be doing but what you end up doing. my college essay is full of the dreams of another person.

[spacejax]

i hate galactic astronomy i keep reading the milky way as mikey way and getting so hard i pass out

I plan to go back to school next fall, so I have a little ovet fourteen months to master all seven subjects. I won't need two full months for algebra 1; cracking open the first chapter, it's all stuff like "here's what a plus sign means" and "variables look like letters, but they really stand for numbers!"

It won't hurt to brush up on factorization, but I think I can bang this one out in a week or two. All the better, because calculus kicked my ass in high school and it's not gonna be any easier now that I'm my own teacher. I passed it once (by the skin of my teeth), but have forgotten almost everything about it in the last decade, so I'll need the extra time to really get it down pat. I have to be able to derive and integrate in my sleep if I'm to stand half a chance at earning an astrophysics major. Astronomy would be slightly easier, but not by much, so I may as well go for gusto. The very first class astrophysics requires is calc 2, so I can't enroll until I'm 100% sure I know calc 1 forwards and backwards. Physics too, but physics and calc feel like two sides of the same coin, so I'll try to work on them at the same time (again, I managed to pull it off once, I'm sure I can do it again).

Chances are these Dummies books will be insufficient for me to grok all this math in one year, so I'll end up buying more textbooks, workbooks, study guides, SAT and AP prep, etc. I had plenty of cram sessions in my first go around at college, but nothing quite like this. This will be a herculean undertaking compared to the easy-A humanities program I coasted through originally. I had no motivation back then, no drive, no goal for "the real world" upon graduating. I went to college because it was expected of me, and I was told I needed it to get a good job. What I wasn't told is that not all majors are created equal; there's not a lot you can do with an English degree besides, well, teaching English. I just hope 14 months is enough time, because I would really prefer not to take another year off; 2024 is the ten year anniversary of when I started college the first time, so it would mean so much more to me if I started again that August rather than put it off until 2025.

I guess it doesn't matter in the end. If I'm not ready, I'm not ready. I can't force myself to start an extremely advanced program before I've mastered the pre-reqs. If I need to start later, so be it. As long as I'm consistently working towards my goal, it shouldn't matter how long it takes.

from yesterday

been so tired lately, but just have to power through these last three weeks of the semester
