Although we take the 24-hour day for granted, in Earth's deep past, days were even shorter. Day length was shorter because the moon was closer. "Over time, the moon has stolen Earth's rotational energy to boost it into a higher orbit farther from Earth," said Ross Mitchell, geophysicist at the Institute of Geology and Geophysics of the Chinese Academy of Sciences and lead author of a new study published in Nature Geoscience. "Most models of Earth's rotation predict that day length was consistently shorter and shorter going back in time," said Uwe Kirscher, co-author of the study and a research fellow now at Curtin University in Australia. But a slow and steady change in day length going back in time is not what Mitchell and Kirscher found.

Today, Earth is enveloped by a thin veil of gas, a narrow band of atmosphere that protects a world covered in lush green vegetation, deep blue oceans, and abundant life. But 4.5 billion years ago, Earth was a very different place: a hellscape of molten lava and barren rock, under relentless bombardment from meteors, and with no atmosphere whatsoever. So how did our familiar blue sky come to be? Breathtakingly realistic animations and a chorus of science experts reveal how the primordial inferno first gave rise to an orange-hued cauldron of toxic gasses that would be deadly to us today. Witness how the first drops of rain splashed down on the searing planet, setting the stage for the evolution of life. And discover how life itself helped create the air we all breathe today.

One pretty cool geological fun fact is that the Scottish Highlands, the Appalachians, and the Atlas are the same mountain range, once connected as the Central Pangean Mountains.

DP x DC: The Most Dangerous Card Game

Ok so Danny has essentially claimed earth as his. And he is fully aware that there are constant threats to the planet. Now he can’t stop a threat that originates on earth (that’s something he’ll leave to the Justice league) but he can do something about outside threats. Doing some research on ancient spells, rituals, and artifacts, he cast a world wide barrier on the planet to protect it from hostile threats so they cannot enter. This will prevent another Pariah Dark incident. However, barriers like this come at a price. You see, there are two ways to make a barrier. Either make one powered up by your own energy and power (which would be constantly draining) or set up a barrier with rules. The way magic works is that nothing can be absolutely indestructible. It must have a weakness. The most powerful barriers weren’t the ones reinforced with layer after layer of protective charms and buffed up with power. Those could eventually be destroyed either by being overpowered, wearing them down, or by cutting off the original power source. No, the most powerful barriers were the ones with a deliberate weakness. A barrier indestructible except for one spot. A cage that can only be opened from the outside. Or that can only be passed with a key or by solving a riddle. So Danny chooses this type of barrier and does the necessary ritual and pours in enough power to make it. And he adds his condition for anyone to enter. 

Now the Justice league? Find out about the barrier when Trigon attempts to attack, they were preparing after he threatened what he would do once he got to earth. How he would destroy them. The Justice league tried to take the fight to him first but were utterly destroyed, so they retreated home to tend to their injuries, and fortify earth for one. Last. Stand. Only when Trigon makes his big entrance…he’s stopped.

The Justice league watch in awe as this thin see-through barrier with beautiful green swirls and speckled white lights like stars apears blocking Trigon and his army’s advance. The barrier looks so thin and fragile yet no matter how hard the warlord hits, none of his attacks can get through and neither can he damage said barrier. That’s when Constantine and Zatanna recognizes what this barrier is. Something only a powerful entity could create. For a moment, the league is filled with hope that Trigon can’t get through yet Constantine also explains that it’s not impenetrable. And clearly Trigon knows this too for he calls out a challenge. 

And that’s when, in a flash of light, a tiny glowing teenager appears. He looked absolutly minuscule compared to Trigon and yet practically glowed with power (this isn’t a King Danny AU though).

And that is when the conditions for passing the barrier are revealed. And the Justice realize that the only thing stopping Trigon and his army from decimating earth. The only way he can get through….is by beating this glowing teenager in a card game. 

Not just any card game though. The most convoluted game Sam, Danny, and Tucker invented themselves. It’s like the infinite realms version of magic the gathering, combined with Pokémon, and chess. And Danny is the master. So sit down Trigon and let’s play.

(The most intense card game of the Justice league’s life).

After Danny wins, this happens a few more times with outer word beings and possibly even demons attempting to invade earth, yet none have been able to beat the mysterious teenager in a card game. Constantine might even take a crack at it and try to figure out how to play. He’s really bad though. Every time this happens, the Justice league worry that this might be the time the teenager looses. Yet every time, he wins (even if only barely). 

Meanwhile, Danny, Sam, and Tucker have gotten addicted to the game and play it almost daily. Some teachers might seem them playing the game are are like ‘awww how cute’ not realizing this game is literally saving the world. Jazz is just happy they aren’t spending as much time on their screens playing Doomed.

#DPxDC #dcxdp #Danny makes a card game to save the world. #Technically he worded the ritual so that they had to ‘beat’ him as those are the most powerful barriers and most reliable. #keys can just get lost or stolen (like the one to Pariah’s Coffin) #A riddle would be useless once someone figured out the answer. Like how no one takes the sphynx seriously anymore. #(Sorry Tuck. But it’s true). #And there is NO WAY Danny is just leaving a hole open for anyone to pass through. No thank you! #So…beating him. But it’s not like Danny wanted to fight so…he edited the ritual a TINY bit. Card games are good. Much less painful too. #Danny Tucker and Sam made the most complicated card game they could imagine. #It’s based on their strategies for fighting ghosts. Capturing them in thermoses. And MUCH based on a on field battle strategy. #It often requires spontaneous thinking on the spot. So Danny? In his ELEMNT. It doubles as practice for his actual ghost battles too. #They had SO much fun making this. #Sam added an entire series of plant cards that act as traps and healing ointments and duds that just take up the field. #Tucker added legitimate hyroglyphics combined with Latin as well as English and ghost speak. #Yes. You actually have to speak that language to play. With proper pronunciation. (Amity Parker’s think the three are talking gibberish.) #I headcanon Sam and Tucker are fluent in Ghost. #Constantine WILL figure this game out SO HELP HIM! #Some of the cards also have combinations related to constellations either in name or placement on the board. #By the way the board is based on a Hexagonal summoning circle with Rhunes along the edges #And the placement of the cards on the board and on what rhune MATTERS. #Also the cards move disintegrate and have certain abilities. Think of Harry Potter Wizard Chess. #But they are normal when Danny plays at school. This is just for ✨effect✨ Against invaders. #Danny faces multiple opponents. He also halts alien invasions. #While Danny COULD stop crime on earth he’s not sure how to fight a normal human and hold back so he sticks to ghosts. #The Justice league are going crazy trying to figure out who this entity is and after deep research are convinced this is some sort of #Ancient being who has protected earth for millenia. They have paintings on ruins and everything. #Danny is not aware they think this. #Raven starts praying to Danny as if he is a god and wrangles the other Teen Titans into doing so as well. Danny is still unaware of this. #Danny is not a King or an ancient. Just a very VERY strong ghost.

Prompt 214

“I did an oopsie.” 

Clockwork paused in his work, gaze turning from his work towards his ghostling (it didn’t matter if he was an adult, he’d always be his ghostling) who was smiling nervously, avoiding his eyes. 

“Oh?” He kept his tone light, even as he worked on untangling a time knot. Honestly at least Danny was immune to any effect of time, even if he couldn’t look into his timelines in exchange. It came with being the other half of Infinity. 

“Yeeah… you know that corner of the multiverse you told me not to go to because you’re working on some time problems? I might have stumbled into one of the worlds in the corner…” 

He stopped his machinations, fully turning towards Danny- Space, his Core whispered and quivered in utter delight at having an Equal in power- with a raised eyebrow, leaning on his staff and silently telling him to explain. 

Danny poked his fingers together, giving a nervous laugh. “So uh, I was just exploring right? Well me and Ellie, you know how she gets when she can’t wander, and um… I er, we might have messed with some things in the creation of it… I didn’t know it was part of that universe, I swear! It was so far at the fringes and halfway into the Zone and I couldn’t just let a universe die before it began and-”

Oh- Oh! His ghostling (and his grand-ghostlings it sounded like) had claimed his first universe! He could put off these time knots, this was a grand milestone for any Ancient, nevermind such a primordial force as one of theirs.

And this is how a DC world came into being with humans evolving with more avian traits. Like wings. And claws. Look, Dan thought it’d be funny if they gave baby humanity wings and Ellie started rambling about how much farther they could travel if they had them and Danny thought it could be cool. Oh well, time to keep an eye on their itty baby world now…

#Prompts #DCxDP #DPxDC #Ancient of Space Danny #Space Core Danny #Moon Core Ellie #Sun Core Dan #Why yes Dan & Ellie call Danny Mom/Dad #Wings Au #They all have favorite bloodlines that they think are neat or they’re rooting for #They also make sure the speedsters (“Look at them! They’re hummingbirds! They can’t focus!”) don’t cause Time Knots #Sam Adores Gotham from the moment Danny shows his friends their lil DC world #And that’s not even starting on the rest of things not even on Earth #Dan appears by Clark’s crib unseen one night & gifts him wings to be able to blend in with his human family #They can’t focus on every little thing but they do their best since it’s their first world #Whenever a hero is revived their wings look like they’ve been dipped in galaxies for several months at least #Jason’s never goes away- they look like a crimson sunrise with stars #Billy got a gift from Ellie & his wings have moon patterns even in his normal child form #Go wild with this

Dp x dc idea 137

Danny uses Constantine to avoid humans from time to time when he is phantom.

The first time it’s was an accident. He blames vlad.

Vlad chasing phantom. Constantine yelling at Vlad about targeting a realms ghost. Vlad won’t reveal himself as plasmius.

Second time. Also by chance. Why was the guy in amity anyways?

Giw shooting at Phantom. John having a crisis about the US government targeting realm ghost.

Then it became a thing.

Ghost hunters? Hides behind John.

Vlad being vlad? He is one with the trench coat.

John is just trying to investigate amity in peace. Not be used as a hiding place by a baby ghost.

Meanwhile Danny found a safe place to hideout and he is going to ham it up. Definitely annoy the guy. But hey people aren’t easily able to kill him.

#dpxdc #dpxdc prompt #John needs a drink #there is a baby realms ghost running around earth #an ancient in the making #and it keeps getting targeted #why isn’t the baby in the realm #he couldn’t risk a war between earth and the realm #so he had to get involved #then the government decided to make it worse #a new thing

How long was it between when Iroh convinced Zuko to take up the Fire Throne, and Sozin's comet? A day? Less??

AU where Iroh convinces Zuko to be the next Fire Lord MUCH earlier in the series. Zuko, who hasn't been in formal education since was 13yo, understandably panics. He barely remembers his lessons on How To Be the Fire Lord, and they were all focused on how to rule during wartime. Not peace. What does an international peace treaty even LOOK like and how does one go about making it???? How does trade work when you're NOT trying to eradicate every other nation????

Book 3 Zuko spends all of his time teaching Aang firebending, interrogating the other members about their culture's traditions and politics, going on Blue Spirit journeys to raid any passing libraries, and reading everything he can get his hands on. He barely eats. He doesn't sleep. He's info dumping about the DRIEST political texts. The gaang are THIS close to holding an intervention or having Toph sit on him until he sleeps.

#the gaang: morning zuko how did you sleep? #zuko (600 pages into an ancient text on the economic significance of grain farmers in the rural earth kingdom): a... agriculture.... #avatar #atla #atla headcanons #i am obsessed with feral nerd zuko #the kid finished formal education at 13!!! against his will!!! #i know iroh was probably teaching him as much as he could but ngl zuko was NOT gonna sit and listen for long when he had an avatar to find #he's panicking and info dumps about ancient international law the second someone looks at him #hakoda is worried about zuko being nervous around him since he's a Father Figure #but zuko skips straight past the trauma and zeroes in on hakoda being an actual political leader!!! who knows stuff!!! #teach him sifu hakoda!!! #my posts

Project: Save Humanity

or something like that

It's no surprise that the Ancients get bored. They are immortal and have all the time in the world to complain about it, sadly Danny joined them after he was crowned.

Their monthly meetings are divided into three topics: Taunting the Observants (Clockwork's favorite topic after they were demoted to helpers, assistants, and other menial jobs), talking about the safety of the Realms (quite peaceful if just as chaotic), and argue.

They- really had nothing to do, and their hobbies eventually bored them. So Danny had a brilliant idea (read: he saw it on a TV show) and decided that they should all become mentors and save one of the dimensions.

Clockwork was about to say that was not a good idea, since it was the same as throwing giants into a world of ants but he needed some fun so he kept quiet. He showed them the dimension of DC and how it was continually being destroyed, the King told them to start their project in that place and select someone.

Clockwork selected Flash because he felt vengeful, Nocturne selected Tim Drake for the same reason, and so they went; each one of the Ancients selecting a "champion" they were going to teach. Although their selection reasons were quite absurd (being that they were selecting their opposite poles or just someone interesting).

Danny being a spirit of protection, selected Jason Todd and secretly Billy Batson, because he was the king and could break the rules (Clockwork rolled his eyes at the comment). The question now was, how did they appear to them and avoid the world's myriad routes of destruction?

Well at least they weren't bored anymore

Pando - The Largest Single Organism by Mass and 14,000 years old, and some perspective on just how old that is.

A random thought came to my head last night...

This is Pando.

All of this? Is a single male aspen tree. This entire thing is a single tree with multiple stems sharing a single root system.

It is the largest tree by mass, and the heaviest single organism, weighing in at 6000 metric tons. For perspective, that's 20 blue whales in mass.

But what also intrigues me is that... well. It's an old tree.

Established in 12,000 BCE, meaning it would be 14000 years old by 2023.

By the the last Smilodons died out in 10,000 BCE, it would have already been 2000 years old.

And Pando is still a youngster compared to the high estimate age of this clonal colony of sea grass estimated to be 100,000 years old.

For perspective, when the last Neanderthal died in 40,000 BCE?

This sea grass would have already been 60,000 years old.

If human civilization (as in, the kind of organized polity that can be identified with things as "states" and "urbanization" among a plethora of other things) was established during 5000 BCE, and thus 7000 years old:

Pando would have already been 5000 years old.

The Sea grass colony would have already been 93,000 years old.

And considering that the oldest vertebrate, that is the Greenland Shark can live for 500 years?

All of human civilization encompasses the lifespans of just 14 Greenland Sharks.

I dunno... it just really shows that we pretty are a tiny blip in the grand scheme of Earth's geological history.

A very humbling thought if you ask me.
