Observations from both NASA’s James Webb and Hubble space telescopes created this colorful image of galaxy cluster MACS0416. The colors of different galaxies indicate distances, with bluer galaxies being closer and redder galaxies being more distant or dusty. Some galaxies appear as streaks due to gravitational lensing — a warping effect caused by large masses gravitationally bending the space that light travels through.

Like Taylor Swift, Our Universe Has Gone Through Many Different Eras

While Taylor's Eras Tour explores decades of music, our universe’s eras set the stage for life to exist today. By unraveling cosmic history, scientists can investigate how it happened, from the universe’s origin and evolution to its possible fate.

This infographic outlines the history of the universe.

0 SECONDS | In the beginning, the universe debuted extremely small, hot, and dense

Scientists aren’t sure what exactly existed at the very beginning of the universe, but they think there wasn’t any normal matter or physics. Things probably didn’t behave like we expect them to today.

10^-32 SECONDS | The universe rapidly, fearless-ly inflated

When the universe debuted, it almost immediately became unstable. Space expanded faster than the speed of light during a very brief period known as inflation. Scientists are still exploring what drove this exponential expansion.

1 MICROSECOND | Inflation’s end started the story of us: we wouldn’t be here if inflation continued

When inflation ended, the universe continued to expand, but much slower. All the energy that previously drove the rapid expansion went into light and matter — normal stuff! Small subatomic particles — protons, neutrons, and electrons — now floated around, though the universe was too hot for them to combine and form atoms.

The particles gravitated together, especially in clumpy spots. The push and pull between gravity and the particles’ inability to stick together created oscillations, or sound waves.

Artist's interpretation of protons and neutrons colliding to form ionized deuterium — a hydrogen isotope with one proton and one neutron — and ionized helium — two protons and two neutrons.

THREE MINUTES | Protons and neutrons combined all too well

After about three minutes, the universe had expanded and cooled enough for protons and neutrons to stick together. This created the very first elements: hydrogen, helium, and very small amounts of lithium and beryllium.

But it was still too hot for electrons to combine with the protons and neutrons. These free electrons floated around in a hot foggy soup that scattered light and made the universe appear dark.

This animated artist’s concept begins by showing ionized atoms (red blobs), free electrons (green blobs), and photons of light (blue flashes). The ionized atoms scattered light until neutral atoms (shown as brown blobs) formed, clearing the way for light to travel farther through space.

380 THOUSAND YEARS | Neutral atoms formed and left a blank space for light

As the universe expanded and cooled further, electrons joined atoms and made them neutral. With the electron plasma out of the way, some light could travel much farther.

Frozen sound waves are visible as miniscule fluctuations in temperature, shown through blue (colder) and red (warmer) coloring.

As neutral atoms formed, the sound waves created by the push and pull between subatomic particles stopped. The waves froze, leaving ripples that were slightly denser than their surroundings. The excess matter attracted even more matter, both normal and “dark.” Dark matter has gravitational influence on its surroundings but is invisible and does not interact with light.

This animation illustrates the absorption of photons — light particles — by neutral hydrogen atoms.

ALSO 380 THOUSAND YEARS | The universe became dark — call it what you want, but scientists call this time period the Dark Ages 

Other than the cosmic microwave background, there wasn't much light during this era since stars hadn’t formed yet. And what light there was usually didn't make it very far since neutral hydrogen atoms are really good at absorbing light. This kicked off an era known as the cosmic dark ages.

This animation illustrates the beginning of star formation as gas begins to clump due to gravity. These protostars heat up as material compresses inside them and throw off material at high speeds, creating shockwaves shown here as expanding rings of light.

200 MILLION YEARS | Stars created daylight (that was still blocked by hydrogen atoms)

Over time, denser areas pulled in more and more matter, in some places becoming so heavy it triggered a collapse. When the matter fell inward, it became hot enough for nuclear fusion to start, marking the birth of the first stars!

400 MILLION YEARS | Dark matter acted like an invisible string tying galaxies together

As the universe expanded, the frozen sound waves created earlier — which now included stars, gas, dust, and more elements produced by stars — stretched and continued attracting more mass. Pulling material together eventually formed the first galaxies, galaxy clusters, and wide-scale, web-like structure.

In this animation, ultraviolet light from stars ionizes hydrogen atoms by breaking off their electrons. Regions already ionized are blue and translucent, areas undergoing ionization are red and white, and regions of neutral gas are dark and opaque.

1 BILLION YEARS | Ultraviolet light from stars made the universe transparent for evermore

The first stars were massive and hot, meaning they burned their fuel supplies quickly and lived short lives. However, they gave off energetic ultraviolet light that helped break apart the neutral hydrogen around the stars and allowed light to travel farther.

SOMETIME AFTER 10 BILLION YEARS | Dark energy became dominant, accelerating cosmic expansion and creating a big question…?

By studying the universe’s expansion rate over time, scientists made the shocking discovery that it’s speeding up. They had thought eventually gravity should cause the matter to attract itself and slow down expansion. Some mysterious pressure, dubbed dark energy, seems to be accelerating cosmic expansion. About 10 billion years into the universe’s story, dark energy – whatever it may be – became dominant over matter.

13.8 BILLION YEARS | The universe as we know it today: 359,785,714,285.7 fortnights from the beginning

We owe our universe today to each of its unique stages. However, scientists still have many questions about these eras.

Our upcoming Nancy Grace Roman Space Telescope will look back in time to explore cosmic mysteries like dark energy and dark matter – two poorly understood aspects of the universe that govern its evolution and ultimate fate.

up all night

pairing: bang chan x gn!reader w. 3.9k genre: shameless smut summary: chan is in the studio working late, stressed about a deadline and pushed to his limit. you convince him to take his mind off work. warnings: reader has somewhat implied afab anatomy but no gendered terms/pronouns are used. petnames used: baby, love, honey a/n: making my smut debut with chan! written for the best person ever

As of late, Chan has been in the studio far more often than you'd like.

You knew he was a workaholic when you got into the relationship. He cared about his career, music, and group so much he'd push himself to the brink. He wrote, composed, and produced all of his own music and wouldn't have it any other way. If he wanted success, he needed to make it himself.

It came at a cost, though. You saw the way his mental health would deteriorate around the time of deadlines. He'd spend almost entire days in the studio, perfecting every last word and beat. You watched as he shaped this music from his hands, sculpting them to smooth out every edge and imperfection.

Even Chan was far too aware how bad it was for himself. You'd try to find ways for him to take breaks, always bringing him food and water to keep him going. He'd thank you in a million ways, with words and fond touches but it ended in him going back to work.

When he finally was home, he returned to the kind and gentle boyfriend you knew him to be. Holding you as you fell asleep and buying your order at the local coffee shop before you woke up. He'd make you breakfast in bed when he had the time, writing love notes whenever he had to leave before you woke up.

As it always happened, a new deadline was approaching. Chan often slipped out after schedules to the studio and worked himself down to the bone. You tried your hardest to spend as much time in there with him, even if it was just laying on the couch scrolling your feed. Every little thing helped.

That night, you'd ordered him some takeout but it was eaten long ago. The time on your phone showed it was half past three in the morning and Chan was at it in earnest. Headphones on, replaying samples and tweaking sounds.

You looked over from your phone when you heard him swear under his breath and take his headphones off. Chan let out a long sigh and covered his face with his hands for a moment before looking back down at his work.

"It- it just won't sound like I need it to. It's not right, it's.." Chan rambled into the air.

You got up from the couch and walked behind his chair, putting your hands on his broad shoulders and massaging them with your fingers. "I know, Channie. Is there anything I can do to help you right now?"

"No, I'm sorry," Chan let out a long sigh and smiled up at you weakly, "You being here is enough."

You felt a stirring in your stomach at the sentiment, but you wouldn't give up that easily. "I can't just let you suffer alone here. Do you want to take a break or wrap up for the night?"

"I won't remember how I want it tomorrow. If I give up on this now, there's a chance I never fix it and it goes out sounding wrong. I can't do that."

"Chris," You stopped massaging his shoulders to turn his chair around, looking down at him, "I know you want it perfect. Write it down on a sticky note what you want and take a break. It's gonna be four soon and I'm not letting you spend another all nighter here."

Chan looked up at you curiously before deflating back in his chair. "I mean- are you sure? If I forget, it's gonna be noticeable, and-"

"I'll remind you. I'll put it in my phone and tell you exactly what you need to fix. Here, tell me what it is and I'll write it down. Got it?"

Chan paused for a moment before nodding, allowing you to open your phone before speaking. He gave you the exact timestamps of the song and the strange producer jargon that you couldn't quite make sense of. You wrote it down word-for-word just as he needed it.

"There, it's in here for you later," You recited it back to him and he gave a confirmatory nod, "You're all set for tomorrow."

"Tomorrow? I can't be done for the night, there's too much to work on and not enough time. I'm sorry, just another hour. Please?"

You shook your head and set your phone down on the table before sliding into his lap, straddling him in the chair. "You're not working another second on those songs tonight, Chris."

Chan looked up at you a little stunned before a sly smirk crossed his face. "Baby, you know that's not fair to me. I need to work and you're doing something dangerously distracting."

"What are you going to do, then?" You replied back, unable to hold back a grin, "You gonna remove me from your lap to do some boring work instead?"

You could see Chan chew on the inside of his cheek before sighing. "It's not boring, and I really should get back to it.."

"Then you're going to have to remove me yourself, because I'm not moving."

Chan let out a dramatic sigh before his hands moved up the outside of your thighs, resting right next to your hips. "You know damn well I'm not going to do that."

"And why's that, Channie?"

His hands moved over your thighs, giving a light squeeze. "God, you're driving me insane. Coming into the studio every night and making yourself useful at every opportunity.. I wanted so bad to stop just to make you feel good. You deserve that, instead of me working the whole day."

"Your opportunity has finally come, I'm all yours if you want me right now."

Chan chuckled, "You could ask me that a thousand times and I could never say no."

You leaned in to his ear and whispered, "Then make your move."

There was a moment of silence before Chan pulled you in for a kiss, messy and rushed. His hands were all over your thighs, waist, back. He couldn't pick a spot and stick to it, deciding instead everywhere needed to be felt over.

You tried to keep things centered, your arms wrapped around the back of his neck. One of your hands played with the curls growing on the back of his head, enjoying the soft feeling through your fingers. It was the only thing keeping you sane.

His hands finally found a place to reside when he hooked them on the hem of your pants, giving light tugs as you felt him squirming under you. Pulling away from the kiss with a grin, you looked down at Chan and his flushed appearance. "So eager.."

"Can you blame me? Now stand up and help me get those off," Chan demanded with a rushed voice, helping get you to your feet as he followed in your footsteps. His usually deft hands were fumbling as he desperately pulled your pants off of you and discarded them to the floor.

Watching him undo his own sweatpants like a madman had you giggling at the sight. "You go one week without any action, and this is how desperate you get?"

"I'm a starved man, honey," Chan's face was red and already had sweat on his brow, "I can't wait any longer, not after all that teasing."

"Teasing? What-"

"Get on the damn couch."

That much was enough to have you laying down on the couch without hesitating. His sweatpants joined yours on the floor, showing off the black boxers he was sporting underneath. A quick glance showed he was pitching an obvious tent.

Although as quick as you were, Chan caught you looking. He raised his brows and laughed, "And I'm the eager one here?"

"You are the eager one here, hardly put your hands on me and you're giving those boxers a run for their money," You responded with your own laugh.

"You little.." Chan shook his head and leaned over you, putting his weight on one forearm on the couch as he kissed you once more. Instead of the fast and desperate pace he had set before, Chan was far slower and delicate. It was almost infuriatingly slow.

You couldn't show how much you wanted him to go faster, that would only prove his point. Instead, he was slowly breaking you down by the second, one arm stabilizing himself and the other hand on your neck, softly stroking your jaw with his thumb.

The waiting game paid off when Chan suddenly took your bottom lip between his teeth, giving it a small tug before he pulled away. "I can't keep this up. You win. Damn you, I'm eager."

There wasn't time for any words to respond before Chan was back where he was before, sloppy and fast. He kissed down your neck, excessive in his biting and sucking at the sensitive skin. Not expecting it, a sound broke its way out of you.

You did your best not to give in to the rest of his harsh and aggressive kisses down your neck. After a week of downtime, he was making up for it in marking your neck as his own. Nobody was going to know who the perpetrator of the hickeys were later (other than the upset staff), but it was the idea that mattered.

There were bigger problems actively stealing your attention. Namely, the small amount of friction made with him moving ever-so-slightly between your legs. It was easy to ignore at first, but the neck kisses were causing the pleasure parts of your brain to kick into high gear.

With one harsher movement than the rest, you were unable to bite back a small, unfiltered sound that escaped you. Chan broke contact with your red and bruising skin to look up with a grin on his face.

"What was that, love?" Chan's tone was starkly different than before, far more teasing and with a dark edge to his voice that you only recognized coming out in bed.

Attempts to take his attention off of it failed and you were forced to fess up in the moment. "You have to stop moving like that, it's driving me crazy."

"Moving like what?" Chan shifted his legs, slotting his thigh directly between yours and pressing firmly against you. This elicited a frustrated sigh, the feeling too strong to push away.

Upon no immediate response, Chan pushed his thigh forward and forced a fuller, more in-tact moan out of you. "Fine, fine- that. Putting your thigh between my legs. That's the thing that's driving me crazy."

"There you go," Chan's words were sickly doting in a way that made you break at the seams, "What do you want instead?"

With his thigh slotted firmly between your own, finding coherent strings of words was difficult. "Just.. get this underwear off me and use your fingers instead."

Chan smiled, clearly pleased with your answer. He moved his leg out from between yours, relieving the pressure and allowing you to breathe. He sat back on his legs as he removed the last layer of clothing from below your waist, tossing it to the growing pile on the floor.

He nudged himself closer, Chan's hand finding its way to where his thigh was once situated before. His middle finger teased you with a circular motion around your entrance, so close to where you needed it most.

"Chan." You demanded, shooting him a glare.

"Okay, okay. Just admiring how worked up I've got you," Chan smirked before his finger pushed inside, slowly filling you up and drawing out a long sigh. He worked slowly yet decisively, knowing exactly how you like it.

That was one of the things you loved about Chan: he knew your body like the back of his hand. Where you were most sensitive, what drove you wild, how rough you liked him to get. He could push your buttons perfectly, string you up in his words until you were tied up into a nice present for him.

Before you could process the first, Chan had already added a second finger and was growing more confident. He worked his fingers in and out in a steady rhythm, not slow enough to leave you wanting more nor fast enough to want to slow down.

"That good, baby?" Chan's eyes met yours, and you saw a different side of him for a moment. The way he sought your approval and made sure everything was right had your heart melting. He had confidence in his abilities, but occasionally needed reassurance.

You nodded eagerly, on the cusp of desperation. "It's good, Channie, you're doing so good," You said between soft moans as his fingers pumped deep, feeling him tease a third and giving him a nod.

The third was always a stretch that had you biting back whines in conjunction to moans, but the feeling was too good to beat. The feeling of being full, on his fingers or otherwise, was what drove you wild.

He kissed you once more, slow and tender as his fingers continued to work. It was hard to keep properly connected, devolving into moaning against his lips with small kisses in between.

"Chris," You said, "Can't wait any longer. Need to have you inside, baby."

Instead of his usual entourage of teasing questions, Chan nodded. He made quick work of his boxers, tossing them haphazardly towards the pile as he moved back to you. He was painfully hard, already leaky and worked up.

"Can I?" He looked down for your reassurance, which came with a nod as he lined himself up. His hips moved forward slowly, feeling him filling you up more by the second. It always took a second to adjust to the size, catching your breath as he bottomed out and waited for your signal.

When you gave him the go-ahead, Chan couldn't help but begin a slow and steady pace. He knew better than to go fast right off the bat- he was a lot to handle. But you could hear him whining softly over top of you and knew he was desperate.

Looking up at him, you cupped his face and pulled him in for a quick kiss. "You can go faster, Chris. You won't hurt me."

You heard Chan let out a breathy laugh before his thrusts grew harsher. Instead of the slow, fluid motion of before; he was faster, precise. Every movement had purpose, each angled just right and hitting the sweet spot.

The sudden adjustment had you whining and letting out louder moans, unable to properly cope. It was overwhelming how good he was at it. All you could do was wrap your hands around the back of his shirt and claw at it helplessly as he had his way.

The fabric getting in the way of your fingers on his skin was beginning to frustrate you. "Off," You managed to get out, "Shirt- off."

Chan grinned, sitting up for a moment and slowing down to a snail's pace to pull his black t-shirt over his head and discard it. You reached up, dragging a hand down his chest and over his abs. Every muscle was yours to touch, to claim.

"You like what you see?" Chan said with a laugh.

Deadpanning, you shook your head. "Shut up."

In a second, he was back over top of you and his pace was back with a new force he didn't have before. It was often he was without clothes, but you weren't under the impression a shirt would be the thing holding him back. Either way, you relished in the fact his back was open to you.

Your nails dug in to his tanned skin, dragging along as he fucked into you steadily. You could hear him sucking air in between his teeth followed by his soft moans. He was always one to endure a little pain.

An idea popped into your head when you thought of before, sitting in the chair in his lap. "Chris, stop for a sec." He immediately halted all movements, looking down at you to make sure everything was alright. "Sit normally, facing the booth."

Chan looked at you perplexed for a moment, but pulled away. He did exactly as you told him to, sitting with his legs spread facing the booth he was just sitting in front of not twenty minutes ago. "What are you planning?" He asked.

You sat up and climbed over to him, straddling his waist with your legs and feeling him hard underneath you. "What I wanted to do to you when I was in your lap earlier."

The realization slowly filled his eyes and a knowing smile returned to his face as he sat back, leaning against the black couch cushion behind him. "Go right ahead."

"If you make me do all the work, we're going to have problems," You glared at him as your hand guided his cock, slowly sinking down on it with a sigh.

Chan's large hands wrapped around your waist, slowly guiding you as you moved up and down. Riding wasn't always the easiest job, and it definitely took some getting used to at the start. Your thighs were slowly building up muscle from the practice.

"God, you're so pretty like that," Chan's voice pulled you from your thoughts, looking down at him to see him smiling up at you. His face was pink and he almost had stars in his eyes.

Seeing just how infatuated he was made your heart race and your face flush, almost forgetting to continue to move. "You're pretty, too."

Your hands were situated on his shoulders to keep steady, but one dragged down and you couldn't resist feeling up his chest a bit. Chan looked up at you smirking again. "Do you ever keep your hands off those?"

Snickering, you pushed down a little harder to see him whine and catch his breath before you responded, "If you're going to keep your clothes off all the time, I'm going to feel up the assets you work so hard on."

"Why do you insist on teasing me all the time? You know what happens when you do that," Chan had a dark look in his eyes that you knew far too well.

Shrugging, you moved your hand up to run through his hair. "Did you ever consider I might like what happens when I tease you?"

"So be it."

Without hesitation, you felt Chan's grip around your waist suddenly tighten. You leaned forward instinctively, both of your hands secured around his shoulders.

He began to thrust up into erratically, fast and without caution or precision. The sound of your skin connecting was obscene, thanking the amount of soundproofing around you as a chorus of moans spilled out of you. Every movement had him deep inside you as you attempted to roll your hips along with him.

"Fuck, Chris," You whined, his pace unrelenting and seeming like he wasn't going to let up any time soon, "Close."

There was a distinctive feeling growing, one you knew too well. The amount of pleasure from every movement was rapidly growing as your body was being overwhelmed. Chan heard you, but didn't stop for a moment. It was almost if it was a sign for him to fuck you faster.

Either way, you were tipping over the edge before you had time to process it, spasming around him as you let you a whorish moan. He slowed down, letting you ride out the high. "That's it, baby," He coaxed, "You got it."

Just as you settled down, you felt him start to work himself into a moderate pace again. Your legs felt shot from your energy levels dipping so you asked, "Do you want to me to move, baby? I don't think I have much in me to keep going right here."

"If it's not comfortable to be right there, of course we can move," Chan said with a smile as he allowed you to reposition to pretty much the same spot you were in before. You laid on your back, Chan coming back over top of you. "That better?"

"Much better," You said with a nod as he went back to the pace he had set before. It wasn't as rough as before your orgasm, but steady enough to keep you whining and your brain somewhat fogged up from the constant pleasure.

Meanwhile, you could see Chan was already getting worked up. His face was redder than usual, his eyes trained on one spot, breathing hard as he kept the effort going to thrust his hips in one continuous pace.

His deep groans and whines had begun to turn into full-fledged moans and swears under his breath. His hands eagerly gripped and kneaded at your waist, seeming like he might accidentally bruise the skin. You were about to open your mouth when he said something.

"Honey, I-" Chan was cut off by his own faltered moan, "I'm close, so fucking close."

You pulled him down to kiss him briefly, keeping his face inches from yours as he continued to erratically thrust. "You don't have to wait, cum for me."

Chan nodded vigorously, his hips snapping back and forth at a speed that had you holding onto the couch for dear life, hearing him let out strained moans and teary-eyed cries as he climbed closer and closer to the top.

All of the sudden, he pushed deep inside you, letting out a gasp and a whine as you felt him come deep inside. His hips stuttered as he slowly rocked them, riding out the high. "Oh my god, that.. that was amazing."

Allowing him a moment to catch his breath, you smiled up at him and gave him another quick kiss. "I've missed you, Chris. I've missed this," You admitted after another silent pause.

Chan nodded, pressing his forehead against yours and sighed. He had finally mellowed out, still buried deep. "I've missed you, too. I'm sorry I haven't been able to do this with you and.. be a good boyfriend."

"No, you're okay. I know how much work matters to you and getting things right means that you see that success you've always wanted. I just always miss you in the times you're working, even if I'm in the same room as you."

"I just feel bad when you're here til way too late at night. Speaking of, what time is it?" Chan slowly pulled out, leaving his mess inside you as he quickly grabbed his phone from the floor, "Oh my god. It's half past four."

Your jaw dropped, standing up quickly as Chan hurried around the room to find something to help you clean up. He settled for his own black t-shirt, telling you he'd just go home shirtless if he had to. Of course it looked terribly stained when you had wiped yourself down, sighing while knowing it probably cost a crazy amount.

Digging through a closet, you found one of Chan's old jacket. Chan was standing shirtless and pacing with the rest of his own clothes on, the defiled shirt balled up in his hand.

"Channie, guess what I found?" You asked with a grin, hiding the jacket behind your back.

Chan looked at you with a nervous smile. "Is it something good? I'm just not super stoked to walk home shirtless at four in the morning.."

You tossed the jacket to him, Chan opting to drop the shirt in his hand before he caught it to not get the filth on it. He happily slid it over his shoulders and zipped it up all the way, picking up the soiled shirt once more.

"Shall we go?" Chan said as he double-checked his pockets and walked towards the studio door.

"We shall."
