DID LIFE BEGIN IN DEEP SPACE??

Blog#467

Saturday, January 4th, 2025.

Welcome back,

Life, for all its complexities, has a simple commonality: It spreads. Plants, animals and bacteria have colonized almost every nook and cranny of our world.

But why stop there? Some scientists speculate that biological matter may have proliferated across the cosmos itself, transported from planet to planet on wayward lumps of rock and ice. This idea is known as panspermia, and it carries a profound implication: Life on Earth may not have originated on our planet.

In theory, panspermia is fairly simple. Astronomers know that impacts from comets or asteroids on planets will sometimes eject debris with enough force to catapult rocks into space. Some of those space rocks will, in turn, crash into other worlds. A few rare meteorites on Earth are known to have come from Mars, likely in this fashion.

“You can imagine small astronauts sitting inside this rock, surviving the journey,” says Avi Loeb, an astrophysicist at Harvard University and director of the school’s Institute for Theory and Computation. “Microbes could potentially move from one planet to another, from Mars to Earth, from Earth to Venus.”

(You may recognize Loeb’s name from his recent book Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, which garnered headlines and criticism from astronomers for its claim that our solar system was recently visited by extraterrestrials.)

Loeb has authored a number of papers probing the mechanics of panspermia, looking at, among other things, how the size and speed of space objects might affect their likelihood of transferring life. While Loeb still thinks it’s more likely that life originated on Earth, he says his work has failed to rule out the possibility that it came from somewhere else in space.

Meanwhile, recent experiments have suggested that earthly organisms can survive in space, at least for a little while. Experiments aboard the EXPOSE-E facility at the International Space Station have subjected bacteria, lichens and plant seeds to the extreme cold and radiation of space for anywhere from a few days to over a year. Some bacteria and other organisms were able to survive the journey, including tardigrades, ultra-hardy animals found everywhere from Arctic ice to the deep ocean.

If an asteroid or comet is large enough, microbes could be frozen deep within, Loeb says.

That could protect them from radiation and the extreme temperatures that turn meteors into fireballs. After they explode onto the surface of a new world, these extraterrestrial colonists could begin to thrive.

In other solar systems, panspermia could be even more likely to occur than in our own. For example, the seven tightly packed planets of the TRAPPIST-1 system, discovered in 2016, might be ideal for life to planet-hop. If we find life there one day, Loeb says, we should pay attention to whether it all looks suspiciously similar. He thinks two neighboring planets with similar biological systems would be a sure sign that life had traveled between them at some point.

"DID LIFE CAME FROM STARS??"

Cas wakes up in a world where all versions of Dean exist at once. He makes sure to validate them all accordingly and hangs this up on the fridge

[tyrusmagocious]

Maybe in a different universe, we’ll be together.

And they were.

The cheerful and selfless dark-haired sweethearts and their confident and endearing golden haired lovers.

[tooselfaware]

Cale needed that evil god's test. Not only to fight despair, but also for his mental health.

He needed to see that there was a world where "Kim Rok Soo" was not left to survive alone. He needed to see all his "what ifs" happen. He needed to resolve all the regrets of "Kim Rok Soo" to fully live as Cale Henituse. Because even if it wasn't his world, he now knows that a "Kim Rok Soo" was happy, surrounded by people he loves, people who would survive with him.

That is how he can loosen the shackles of fear of being alone again as Cale. "We will all survive" is not just a random mantra for him. He needs it to be true. He has had so much loss and grief in his life.

Even if he doesn't really say so, that grief was what kept him going. To "not waste" the sacrifices of all those who saved him, he kept surviving. But that is also why he's reckless despite "valuing" his life.

I think, subconsciously, he thinks that if he can save more people, then that would be a good "payment" for those who saved him. His "slacker life" is basically world peace. 🤭

Back to the point... The test showed him Kim Rok Soo and everyone he cares for survive, so now he has more courage and less doubt to face WS because he wants a life like Parallel KRS', as Cale Henituse.

Previous: Prologue

➨ Chapter One

Next: Chapter Two

Premise:

The multiverse theory is the idea that there is not only one universe but, instead, an infinite number of universes, parallel to one another.

You and Tenko were heroes in your universe. The war came and went, and that left only you. When you are thrown into a universe parallel to yours, you find out the hard way just how similar and different it is from your own.

A/N: I know this is technically the first chapter BUT, there is a prologue for this story. So if you haven't checked that out yet, it's linked above, and I highly recommend reading that first.

If you'd prefer to read on Ao3, here is the link:

Otherwise, enjoy!

♡ ♡ ♡

CHAPTER ONE

The rain grew heavier, encouraging you to turn away from your departing friend in favor of heading home. Combined with the cool early-spring air, you were sure you’d get a chill. It was a little surreal, being a top-charted hero who helped save the world from villainous destruction and taking transit like you were a typical commuter. No one batted an eye. They probably didn’t even recognize you regardless of whether or not you were dressed for work.

That’s how the world was.

They cared for the first few weeks following the end of the war, but that dwindled as weeks stretched into months. Once the roads were rebuilt and everyone resumed their daily lives, there wasn’t much to remind them of what had happened.

And after the upheaval of hero-dominated society, the raving over who was Number One and which debuts showed the most promise declined to almost nothing.

Heroes were becoming a thing of the past.

Your apartment was reminiscent of that fact. For nearly your entire life, you were chasing after some dream of becoming a hero and making the world a better and safer place. Yet there was barely anything decorating your walls or countertops to suggest such a thing. You had been living there for roughly two years, just after the end of the war, but there were countless boxes shoved aside still waiting to be unpacked. You’d peered inside them a handful of times, but you decided it was better that their contents stayed tucked away.

After entering your apartment, you wasted no time in peeling off your soaked clothing. The various articles landed on the linoleum flooring with a wet slap. You kicked your pants to the side and shuffled over to one of the stools at your kitchen counter. You grabbed a throw blanket that was draped over the back of one of them and wrapped it around your shivering body.

A pitiful groan emanated from your stomach just before it cramped up uncomfortably. With a slight wince, you huffed and checked your fridge for any remaining left overs or easy meals.

What a sad sight that was. The light inside of the fridge illuminated your face as you stared at mostly empty shelves.

Whatever.

You could always order take out.

Swiping away missed calls and unread messages, you began a search for anything that sounded appealing.

Maybe if you’d gotten a text from Toga or Iguchi, you would have cared. But Toga was obviously busy with her big move, and you couldn’t remember the last time Iguchi had reached out to you. For a while, you two would try to make time to grab lunch or play games like you used to, but you both knew it was hardly the same anymore. You saw each other less and less, until your meetups stopped altogether.

Nowadays, your dreams were filled with memories rather than hopes for the future. Your heart and soul longed for the experiences and the people in your past, and the only way you could indulge was in your sleep. Waking up afterwards was like pulling teeth as you tried your utmost to return to whatever memory had been playing out in your mind.

The doorbell rang.

Your food was left outside your door, and after bringing it in, you ate maybe half of it before banishing the leftovers to the fridge of doom. The light filtering into your apartment gradually turned cool and dim, meaning it was just late enough for you to justify turning in for the night. You didn’t bother putting on a dry set of clothes, instead opting to crawl into bed wearing your mildly soggy undergarments.

Every day was the same. You’d work, go home, eat, and sleep. You never went out anymore, and you were certain that if you picked up your TV remote, it would leave a silhouette behind contrasting the dusty surface.

The only bits of ‘décor’ you had were photographs strewn about your TV stand. None of them were framed. They just lay there for you to peruse whenever you wanted to inflict even more emotional damage upon yourself. The old photos of your friends from work and school before the war best served for collecting dust.

There was one that stood out from the rest. It lay on your nightstand, still sheen from its frequent handling.

Delicately, you picked it up, just as you did most nights, and peered down at it.

–

It was the day Tenko Shimura officially started as a pro-hero at the AFO Hero Agency.

He spent the past few years with them as an internship and a work study, but everyone felt that starting there as a graduate was something to be celebrated. So you all made a day of it.

Everyone was there, and the conference room had been decorated and rearranged to better fit the occasion. Several platters of food lined the tables, filling the room with a heavenly aroma that complimented the chatter quite well.

Tenko wasn’t typically one for parties or huge get-togethers, especially when he was the focus, but he was kept from standing idly as people took turns congratulating him. You could tell he was beginning to grow tired of all the socializing.

You chuckled as you stepped up to his side, walking him away from his dying conversation. You watched as he relaxed his tense shoulders and dipped his head back with an airy groan.

“How does it feel being the life of the party?” you snickered.

He glowered at you through his messy, black bangs before placing a gloved hand on your shoulder and giving you a strong shove that sent you stumbling. You cursed as you regained your balance, ready to retaliate but he was already walking away from you.

“Hey!” You trotted back up to him.

“You’re next, you know,” he said, looking at you from the corner of his eye.

You tilted your head to the side, “To be the focus of a party?”

“To join the agency,” he corrected. “When you graduate, you’d better.”

“Oh, of course.” You grinned at him before narrowing your eyes slightly. “But only if you promise to stick around until then.”

“I’m planning on it,” he chuckled, “Unless you piss me off.”

It was your turn to jab at him, but, unlike you, he kept his balance, barely even stepping to the side.

The two of you found a secluded place to sit and chat idly but it was mostly filled with a comfortable silence as you scrolled on your phones. You were only granted a few minutes of social reprieve before Magne came looking for you.

“Are you two aware that the party isn’t out here?” she said, crossing her arms like a disappointed mother.

You and Tenko exchanged a glance, but neither of you said a word.

“Get your asses in there!” She scolded, shepherding the two of you back to the celebration. “We’re taking a group picture.”

Everyone crowded together. You were pushed up against Tenko’s side, and the two of you felt Iguchi drop his arms onto your shoulders. He stood behind you, still clearly visible between your heads, and Toga latched herself onto your free arm. Touya lurked on the very edge of the group while Compress took on a dramatic pose to ensure his theatrics would be captured for all of eternity.

One of Jin’s doubles positioned himself in front of everyone, partially crouched down and shuffling this way and that in order to get the perfect angle.

He didn’t have to tell you to say ‘cheese’ to get you to grin from ear-to-ear.

You felt Tenko’s gloved hand press against the small of your back as the camera flashed, immortalizing the occasion.

–

Seeing everybody grinning back at you in the photo four years later made your heart ache in many ways. You were happy that you possessed that memory as well as a picture to always remind you of it. But you were also tormented by the fact that it would never be recreated.

Unfortunately, plans didn’t always come to fruition.

When you started as a pro-hero at the agency, the world was in too much chaos to celebrate. And even if you held a celebration once everything settled down, Tenko wouldn’t be there to congratulate you.

In spirit, maybe.

When you really thought about it, almost everyone would be missing.

Magne had passed many years ago, when your team was assigned to the Overhaul-Eri case. The war took away Jin, Touya, Sensei, and, of course, Tenko. Iguchi would have stuck around long enough, but Atsuhiro was forced into retirement when the war first started.

In a way, the villains got what they wanted. Countless heroes were decommissioned, and those who remained were no longer viewed in the same positive light as they once were. Criticism was high if a hero couldn’t carry out a job flawlessly and without any casualties. Even then, you were always at risk of being deemed a ‘fame-chaser’ or that you were only in it for the money.

The only heroes that remained were the honest and the resilient.

You liked to think you were both, but as time went on, you grew more unsure. In the beginning, you were more than eager to make a positive impact on people’s lives, regardless of whether or not you were credited or paid for it. Eventually, you met everyone at your agency, and hero work changed your life for the better. Even if you failed a job, you had people by your side to pick you back up and keep you pushing forward.

But now?

Now, you were tired.

You no longer had your support system keeping you motivated and in good spirits. While you still felt pleased with every life you protected, that feeling of fulfillment would be gone by the time your head touched your pillow.

That’s where you were at currently.

With a deep sigh, you let go of the photograph, letting it fall back onto the nightstand, and rolled onto your back to stare at the ceiling. You shut your eyes, but you knew it would be hours before you actually fell asleep. You would either sleep the day away or you’d barely sleep at all. Rarely could you find a balance between the two.

Usually, you would stay up thinking about how everything ended up the way it did, and whether there was anything you could have done to prevent it all from happening. What could you possibly have done so that your team would still be at your side?

If you were split up differently during the Overhaul raid so that you were in Magne’s group, you could have pushed her out of the way of Chisaki’s fatal touch. If you had stuck by Jin’s side instead of letting him go into the Paranormal Liberation Front’s headquarters alone, you could have fought off Hawks before he landed his deadly blow.

And Tenko…

You’d probably have to end the war all on your own in order to save him. He was at the forefront of every battle, leading the charge. He had no regard for his own safety. He gave up his own body so that Mr. Shigaraki could transfer his quirk and conscience to it. You’re pretty sure that was the point of no return.

After that, you don’t think anything that came out of Tenko’s mouth was truly him.

Whether or not he could even hear you scream and cry for him in the final moments of the war would remain a mystery.

The heels of your hands pressed deeply against your eyes as if you could physically push the thoughts out of your head. You couldn’t do this tonight. You needed to do something, anything, other than lay there and dwell on things of the past.

How could you have known what was to come?

Throwing off your covers, you ripped the last garments from your person and got up to change into something clean and dry. You had to get out of your sad and dingy little apartment. You wiggled your way into a spare hero suit after deciding that lending a helping hand for the night was your best chance at clearing your head.

You made your way back to your agency as quickly as you could through the frigid rain. It wouldn’t be so bad if it were summer time, since the warmth would typically counteract it, but you still had a few months of spring to get through. By the time you arrived, you were a bit damp, but you found it hard to care. Pulling your keycard out of your wallet, you tapped into the system so you could get in.

Even though it was late, there were still a few people around in case of emergency, and none of them were surprised to see you stroll in. Two of them were people you had graduated with, though they did their work studies elsewhere.

��Hiya,” Minji, a pink-haired and bubbly girl, sang to you in greeting. She was sitting alert at her desk, ready for whatever report came her way.

“Hi,” you nodded, walking over to her.

Another girl you attended school with was lounging in the space adjacent to hers, leaning back as far as her chair would allow, both feet propped up on the desk. Her head turned over in your direction before she acknowledged you, “Need something to do?”

“If you have anything,” you said with a shrug.

“I think Sakiko got a call-in just a few minutes ago requesting a hero to accompany the transport of a villain,” Minji chimed with a soft smile, eyes darting over to her companion.

“Uh, yeah. Let me get the details on that,” Sakiko mumbled as she kicked her feet off of the desk and scooted closer to search through her computer. “Yeah, so the police want to transport a villain to a higher security prison… His name is Dai Uchuu. He was involved with Overhaul during the raid, but he was able to escape, and there’ve been no updates on his activity since. We also don’t have any official documentation but his quirk is believed to be a teleportation-type triggered by his hands making contact with each other.”

“Sure, that works. Send me the address, and let them know I’ll be there.”

“Yes, ma’am.”

The station wasn’t too far from the agency. You walked for maybe ten minutes before you could see its lit-up sign at the end of the block. There was a brief flicker but it recovered almost immediately. However, the lights within the station began to spasm on and off, which was slightly more concerning.

The police relied mainly on quirk-nullifying restraints and cells to prevent breakouts. If they were having issues with the power, then the nullification effects would likely be down, and that would be quite the problem.

You quickened your pace and rushed into the building. The first thing you noticed was the plethora of odd objects that had been thrown about the lobby. There was a bicycle on top of the desk, a canoe sticking out from one of the doorways, and a large tub of paint that was actively rolling across the floor, leaving a trail of blue behind it. You could see a large splatter on the wall where you assumed it had made contact.

The second thing you noticed was the silence. Despite the apparent chaos, not a single cop was in sight. You couldn’t even hear any voices emanating from adjacent rooms. There was no one.

You briefly reported the situation to your agency through the communicator strapped to your forearm and cautiously proceeded onto the other rooms. The holding area and the locker rooms were empty and in similar condition to the lobby. You were about to say the same for the offices, but you noticed a quiet murmur coming from behind one of the far desks.

In a slight crouch and with light feet, you slinked in that direction. As you peered around one of the desks, you saw the villain, Uchuu, still dressed in his medieval garb. His colorful back was turned to you as he rummaged through a filing cabinet. The quirk-nullifying restraints dangled from one of his wrists. One of the officers must have gotten that on him after he had a go at most of the building.

But then why hadn’t you run into him?

You silently reached forward and cast your quirk, causing his clothes to freeze him in place. As you walked forward, he began to snicker. You faltered a step at his odd behavior.

“Of course you would be the one to show up,” he spoke with a strange accent.

“I guess?” You positioned yourself in front of him. You wouldn’t be able to attach the restraint he had on to his other wrist due to it being frozen along with him, so you pulled out one of the few that you carried. “What happened to everyone?”

You reached forward to attach the new set of cuffs, but as you did, you caught sight of the file he was holding.

Was that your name?

The cabinet he was going through was supposed to contain criminal profiles. Just as you were about to question how and why he had one that was addressed to you, you felt a sharp pain on the back of your hand.

“Ow! What the fuck?!” You jerked away and were about the curse the man out for fucking pinching you, before processing the fact that he was standing up. Your surprise had caused you to release your quirk, freeing him.

“What a fortunate turn of events this has been,” he drawled with a wicked grin. You narrowed your eyes and raised your arm to use your quirk again, but before you could, his hands clapped together.

You felt your entire body lurch forward, and for a moment, everything was black.

You figured you must have blinked because it was only a second before you could see clearly again. A wave of nausea began crawling its way up your belly, but you did your best to ignore the feeling while you frantically looked around.

It took you a moment to realize that Dai Uchuu was no longer in front of you. The filing cabinet was closed and no more papers were littering the floor. He must have gotten what he was looking for and bolted… Were you seeing black for longer than you realized?

If he clapped his hands, he must have tried using his quirk but he still had a restraint around one of his wrists. That should have been enough to still subdue his quirk, so he had to be around somewhere.

You quickly made to leave, almost bumping into an officer who was standing up from his desk. He shouted after you, and you gave a clipped apology but kept on your pursuit. As you entered the lobby, you almost ran head first into another officer and had to pause to move out of her way. She didn’t seem to be in much of a hurry though.

“Do you know which way he went?” you quickly asked her as you began walking backwards towards the exit of the building.

She looked perplexed, doing a double take of you. “Who? What were you doing in that area?”

He must not have gone that way otherwise, given his outlandish appearance, she surely would have remembered. That meant he would still be in the building.

“That’s where I found Dai Uchuu. He was going through some of the criminal records but he managed to get away,” you explained, slowly walking back towards her. “I’m not sure what he was looking for, but I’m guessing—”

“Who are you?”

What?

“I’m the hero assigned to your case,” you said matter-of-factly. “You guys sent in a request for help, so I came.”

She jerked her head back, scrutinizing you. “We didn’t—”

“Listen, if you didn’t see him come this way, he must still be in the building. You guys should look for him here, and I’ll check outside in case he found some other way out,” you said as you began a quick pace into the lobby.

They made quick work of cleaning up, because all of the foreign objects that were thrown about when you’d arrived were nowhere to be seen. You noticed even the giant paint splatter was gone. Actually, the entire place looked spotless of even normal dirt and wear-and-tear. Maybe you should’ve hired them to clean up your apartment for you.

The room erupted in clamor as you booked it outside. It was a lot clearer out without the rain, but you still couldn't see any sign of the villain. Leaving it up to intuition, you started sprinting down the road to your left as you updated your agency through your communicator with a request for more heroes to help search.

You were barely running for a minute before you began feeling overheated. There was no way you were that tired already, you didn’t go through all that training for nothing. Then, you realized it wasn’t your body that was too warm, it was the air around you. Not even ten minutes ago, you were freezing your ass off as you trudged to the station in the rain. Now, it felt like the temperature outside was pushing 70 degrees.

Someone had to be controlling the weather. Quirks like that were rare, but not unheard of. Either way, that was somebody else’s problem. You were a little preoccupied at the moment.

You were growing irritated that you hadn’t heard anything from your colleagues. Minji was usually super responsive. She must have stepped away and left Sakiko in charge, which would explain the lack of urgency on their end.

Your pace began to slow as your energy grew more and more depleted.

Your end of the search was proving to be pointless. You passed a run-down convenience store when you decided it would be best to head back to the station to see if the police were fruitful. You heard the chime of the shop’s bell too late, turning on your heel to retrace your steps and crashing into someone as they were exiting.

You jostled back.

There were two people, and your collision caused them to drop their bags, scattering the contents. You crouched down to help them pick up whatever had fallen, hoping they didn’t have any paper products for the rain-soaked ground to get soggy.

Your eyebrows pressed together as you picked up a messy handful of napkins. You looked down at the sidewalk and pressed your hand against it.

It was bone dry.

That couldn’t be right, there’s no way the water would have evaporated that quickly.

You couldn’t ponder the strange occurrence for long as the shoe of one of the people stepped closer to you. Hurriedly, you scooped as many items back into the bag as you could and peered up at them with an apologetic smile. They were already reaching toward you with an open hand. It was a bit too close to your face for your liking, so you leaned away as you stood.

“I’m so sorry. I wasn’t paying attention.” You pushed the bag into their hand and finally looked at the person’s face to see it was mostly covered by a black face mask and a hood. Despite that, peeking through a plume of dusty blue hair was a pair of fiery red eyes that felt as if they were burning through your soul.

HOW ARE BLACK HOLES CREATED, AND HOW DO THEY GROW??

Blog#461

Wednesday, December 11th, 2024

Welcome back,

In 2017, astronomers started finding monster black holes in the very early universe. Containing roughly a billion times the mass of our Sun, these black holes were surrounded by disks of infalling matter shining so intensely that we can detect them across immense stretches of space and time.

These gravitational giants existed when the universe was only 700 million years old, or 5 percent its current age. At that point in cosmic history, the universe was still a toddler. Gravity was just beginning to rein in clouds of gas and dark matter to form structures that would later evolve into mature spiral and elliptical galaxies. Stars were beginning to pop into being, but they do today.

According to the traditional picture of black hole formation and growth, the universe at this time simply had not existed long enough for black holes to bulk up to a billion solar masses.

So, based on our general understanding of how black holes form and grow, these black holes should not exist.

And yet they do — posing a major challenge that astrophysicists have yet to unravel.

Quasars are brightly shining beacons of light and energy generated by the accretion of material onto supermassive black holes. In the 1990s, astronomers using a combination of ground- and space-based telescopes started to find extremely distant quasars powered by black holes of a billion or more solar masses.

By the mid-2010s, it was no longer a big deal to find quasars dating back to 1 billion or 2 billion years after the Big Bang. But theorists had a difficult time explaining how such massive black holes could have arisen so soon in the universe’s history.

For quasars and other objects that existed many billions of years ago, it’s meaningless to express their distances in terms of light-years. The universe has expanded so much between then and now that astronomers instead refer to an object’s redshift, which is a measurement of how much cosmic expansion has stretched the object’s light toward redder (longer) wavelengths.

For years, astronomers such as the University of Arizona’s Xiaohui Fan have been identifying quasars at redshifts as high as 6, when the universe was about 900 million years old. They’ve even found a few around redshift 7, which corresponds to an era when the universe was about 735 million years old. But in late 2017, an international team led by Eduardo Bañados of the Carnegie Institution for Science announced a quasar at a record-shattering redshift of 7.54. This quasar, designated J1342+0928 (J1342 for short), based on its sky coordinates in Boötes, was radiating 40 trillion Suns’ worth of energy at a time when the universe was only 690 million years old.

The team found J1342 by mining data from NASA’s Wide-field Infrared Survey Explorer satellite, the United Kingdom Infrared Telescope Deep Sky Survey Large Area Survey, and the DECam Legacy Survey. They used the 6.5-meter Magellan Telescope in Chile to measure the quasar’s redshift, while observations with the 8-meter Gemini North Telescope in Hawaii enabled the team to estimate the black hole’s mass: around 800 million Suns.
