everything is physics

One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don’t throw it away.
—  Stephen Hawking, A Brief History of Time

You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules of potential energy—enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.
—  Bill Bryson, ‘A Short History of Nearly Everything’

Single particles of light (photons) simulate quantum particles travelling through time were just used by scientists from the University of Queensland, Australia. They showed that one photon can pass through a wormhole and then interact with its older self.

The study of closed timelike curves (CTC’s) provides valuable insight into particles that can loop back on themselves, breaking free of linear time. One aspect of general relativity that has long intrigued physicists is the relative ease with which one can find solutions to Einstein’s field equations that contain closed timelike curves (CTCs) causal loops in space–time that return to the same point in space and time.

Closed timelike curves are a necessary concept to understand this experiment.
CTCs are used to simulate powerful gravitational fields, like the ones produced by a spinning black hole, that could theoretically (based on Einstein’s theory of general relativity), warp the fabric of existence so that space-time bends back on itself. This creates a CTC, almost like a pathway to travel back through time. The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. The feat should be possible based on Einstein’s theory of general relativity, which describes gravity as the warping of spacetime by energy and matter. An extremely powerful gravitational field, such as that produced by a spinning black hole, could in principle profoundly warp the fabric of existence so that spacetime bends back on itself. This would create a “closed timelike curve,” or CTC, a loop that could be traversed to travel back in time.

((A study of the biologists on Elsewhere University, a continuation of the posts on statisticians and physicists by Canadianwheatpirates. Also on Ao3 )) 

Being a biology student on Elsewhere University is simply put absolute torture.

It’s in the nature of the Gentry to avoid the science students. Disapproving of everything and everyone that wishes to pin them down, put rules to them or uncover their secrets. It’s an uncomfortable truce, but in general the science students are bothered a lot less than the others. Especially the chemistry students are given a wide berth after the incident with their professor. Most science students are perfectly all right with this. No better guarantee for safety, after all.

The biologists? Not so much.

After all, what’s more of a novelty, a marvel, to a biologist then an entire hill filled with strange new species. Unclassified, unidentified, with unknown behaviour patterns and illogical body plans, not to mention sentience and powers beyond your wildest imagination? Irresistible!

The Fair Folk won’t touch you with a ten-foot pole, of course, but that only makes it more intriguing.

In a way, the other science majors have it easy. The things they study stay in place, mostly. The things they observe don’t tend to stare back. Of course, you could look away, but where’s the fun in that?

I’ll warn you beforehand, it’s not easy studying biology here. Unless, of course, you have a whole heap of self-control and patience stored up. Yes, the Art and English majors get taken most frequently. Yet when it comes to mysterious disappearances and weird unexplainable accidents, biologists take the lead. We’re magnets for trouble, sneaking around the boundaries and putting our noses where they do not belong. Prying and spying and generally being a hassle to the Fair Folk. Suddenly finding your life returning to crushingly normal as They retract their hands and even their eyes from you is said to be the most favourable outcome.

You’ll get to hear the stories anyway, though. After all, biologists are and odd breed of scientists. Jacks-of-all trades, we learn a bit of everything. Some chemistry, physics, math and statistics. They even put us in philosophy class every now and then to everyone’s great displeasure. As if we’re the ones who should be most concerned with morality and ethics on these grounds! Either way, you’ll get to know a lot of people from different studies as well, so even if the gentry decide to turn their back on you, the gossip will reach you nevertheless.

And after all, there’s plenty of cool things to study that aren’t magical at all! From ancient crab species with blue blood, saturated with copper, to jellyfish that keep turning back into their larval state, rendering them essentially immortal. Plants who’s body temperature rises with fifteen degrees when they flower or bacteria that eat plastic, form rock-hard spores or breathe sulfate. Not to mention fungi the size of a football field. No magic required!

Other students say we take after our subjects too much, and I guess they’re right. When it comes to creatures it’s universal among biologists that we like it bizarre! And yeah, we fit the bill. I know from experience many have the tendency to take their ‘work’ home with them. From odd exotic plants to weird, unfamiliar pets. Rooming with a biologist means there’s always chance of finding preserved carcasses in your fridge, or sometimes boxes with seeds that need to be kept cold until April, then they can be planted in the topsoil during the full moon. Be careful when watering the plants, some are from the desert and can easily be drowned. Mind the small tree with the massive, hand shaped leaves in the windowsill! Three seeds are enough to kill a human. The leaves aren’t that bad but you should still wash your skin thoroughly with soap after touching them.

It doesn’t matter if you’re an ecologists, cell biologists or geneticist. We all love nature, living things (and dead things, on occasion) and will try to keep them close. Your dorm will never be silent with the cries and scurrying of unfamiliar animals or rustling leaves as background noise.

Come to our labs if you have a free afternoon, they’re the prettiest this university has to offer! We have plenty of flowers in all colours, a small palm tree on the workbench and a huge aquaria full of colourful fish. Plus a cage with over forty species of beetles, shining like gemstones. Also a big collection of super-rad skeletons! Regular animals, fish, some beasts with too many limbs that look like the art students were in charge of the assembly. Most look unnerving (except the centaur, that one just looks dumb) and others can never quite tell if they’re perhaps Fae in origin or just weird-ass earth creatures (the biologists like it bizarre, after all). If you figure it out, don’t tell them!

And plants, so many plants. Don’t water anything though! Leave it to the professionals. Also if you see any empty pots, for the love of everything don’t throw them away! There’s no telling what’s beneath the dirt. There might be a living plant hibernating down there! Or maybe something else.

Please don’t touch the dead things either! Both for your own safety and for our sake, a few of those have yet to be dissected. Also, some of them might not be as dead as you think.

Oh and, oh what? The plant in the corner, you mean? Don’t worry about that, it’s not actually glowing. It’s just covered in a layer of thin, purple hairs! We suspect it’s to protect it from UV light. Nothing magical about it! We think. We’re still not entirely sure how it keeps making those sad humming noises though, but we’re bound to figure it out soon!

Also keep an eye out for the various pets the biologists are keeping, it’s a very interesting bunch. Much more varied than your typical cats and dogs. I’m still not entirely sure if keeping pets is allowed in the dorms but whatever, no stopping us. The lab rats used in the ‘animal behaviour’ practicum of the ‘development and growth’ course supposedly get disposed of after the experiments are finished, so they are free for the taking. Just bring a bulky jacket with a hidden pocket. Quite some biologists have one, although it’s a chore to smuggle them out.

Some of them are somewhat… odd, even though we didn’t do anything with them except observe their behaviour. Perhaps it’s the exposure to Fae magic? They make good pets, nevertheless.

(There’s another odd advantage to caring for plants and animals. Pets don’t normally do favours, and aren’t bound by promises, but this place has a way of altering things. It’s no certainty but perhaps one of the creatures you take care of may one day repay the favour. There are many friends to be found for the lifesavers. And as a biologist on Elsewhere’s grounds, you need all the friends you can get. Just make sure you treat them well.)

You may find injured creatures on campus occasionally. Just remember to check if any potential pets are sentient, deadly or collared before you take them. And remember, the crows and the lone fat skunk are absolutely off limits. Be wary of the swans, as well. Always be wary of the swans.



Vulnerable Shawn based off of the first line of Running Low: Weeks on end I’m on the road / Start to lose my sense of home / But not based on the song in its entirety. It’s not a breakup imagine, not in the slightest. 

Your name: submit What is this?


Your phone vibrating on the desk in front of you forces you to look up from your physics notes. Shawn’s name is on the screen, and you hesitate for a moment, but only a moment before you snatch your phone off the desk and speedily walk out of the library, leaving your friends and your books behind. Shawn knew you were studying at the library tonight because you had been texting him earlier. He usually respects your study time, and anytime he knows you’re doing something. He’ll text you randomly even if you’re busy, but he usually only calls you if something is important. You both have busy schedules and are very understanding of the fact that there are certain days you have to be content with just a few text messages throughout the entirety of the day.

“Hello?” You answer as soon as you step out into the cool nighttime air.

“Hi y/n.” Comes his reply, and you wonder if there is something wrong, although if there is, he’s not saying it right away because he lets a moment of silence hang between you after he greets you. 

So you speak, “Hey baby, what’s going on?”.

He exhales loudly on the other side of the phone, so loudly that you can hear it on your end. You can tell that he’s frustrated or exhausted or something, but you don’t know right away exactly what his emotions are at the moment. “I just miss you, I need you here with me. ” He responds.

crazy-almost-everything  asked:

I just found your blog and I was wondering if you could elaborate on a star a bit more. Like, what is a star made of? And how was it made? Thanks!

Ok so stars are formed when giant (like, really giant) clouds of mostly hydrogen (and some helium) collapse. This means that their own gravity pulls them close together, compressing it. As the gas compresses, it becomes more dense and much hotter. Eventually, the star becomes hot enough to undergo nuclear fusion, meaning it turns hydrogen into helium, releasing energy. At this point, we say that the star is “born,” since it’s fusing hydrogen into helium.

Stars are about 75% Hydrogen, 24% Helium, 1% other elements (at least, when they’re born). The temperature of the star itself is so hot that the electrons and the nuclei of the atoms are separated, which is called plasma. The actual “star” part is composed of plasma, and the outer parts, which are cooler, are usually made of gas. 

I hope this answered your question, if it didn’t or if you have more, feel free to ask me // let me know!!!

Thank You - Loki X Reader (NSFW)

Author’s Note: Hope you enjoy ! Some Loki smut for all you dirties. Sorry it took so long, by the way.

Warning: smut, NSFW, slightly dominant reader, then Loki, oral on a man

Request: I! Can you write a Loki imagine about him protecting her from an enemy? I got this idea from a person’s request:p



Words: 1,355

You were surprised when Thor brought Loki to fight with the rest of the team. Not that it was a bad thing. You found yourself incredible attracted to the god, but kept your feelings to yourself. He was cold and sarcastic and you knew that he would never be interested in a measly human like you. His dislike for the human race wasn’t necessarily a secret.

The mission involved a large group of super soldiers created by HYDRA and aliens. You didn’t even want to rationalize how these two groups decided to work together. Instead, you focused on helping beat them and keeping civilians safe.

The fight was long. You all had underestimated how many enemies you would have and the team was definitely on the smaller side in comparison. You shot your gun to as many HYDRA and alien bodies as you could. If anyone crossed your path, you would shoot. You were grateful for thinking of bringing extra ammunition.

You were too preoccupies shooting at whatever was in front of you that you completely forgot to cover your back. You were an agent, you were trained for missions like this and when you heard a bullet shoot and whiz past your ear, you cursed yourself for being so stupid.

“Shit,” you said, turning and shooting at the soldier that shot at you. You fired your gun at him and you watched him go down. Another soldier showed up after him ad you tried to fire, but you were out of rounds. Your heart leaped to your chest as you tried to reload your gun as fast as possible.

You weren’t quick enough and the bullet shot out of the man’s gun in slow motion. The bullet approached you and your limbs felt like cement and you couldn’t even move. You knew that there was no way that bullet wouldn’t hit you.

Until you saw it curve. You questioned gravity, physics, everything you could think of. You couldn’t understand how exactly a bullet curved in mid air, back towards the soldier that shot it. You looked around and were surprised to find Loki making his way towards you.

You glanced at you as he continued to fight, using his magic, and you were slightly confused. He looked upset, but he didn’t say anything, so neither did you. You turned around, finished reloading your gun, and continued to fight

After hours, you were done. The fight was finished and you were grateful the team only suffered minor injuries. You all got lucky this time.

On the way back to the Avengers base, you kept glancing at Loki, who kept staring at you, his brows still furrowed and he looked very upset. You wanted to talk to him, but you felt awkward and you didn’t exactly know what to say to him.

You all arrived to the base and you all started walking towards your rooms.

You saw Loki walk with Thor towards their temporary room and you jogged after them.

“Hey, wait up!” you called and they both turned to face you.

“Lady (Y/N)!” Thor exclaimed, “you fought valiantly.”

You smiled at him. “Thanks, Thor. Um, I was hoping I could talk to Loki.”

You glanced at the blue eyed god and he was staring at you intently. Thor clapped him in the shoulder and continued making his way to his room, Loki staying behind.

“yes?” he spoke, his voice clear and smooth.

You turned towards him and blushed. “Um, I wanted to thank you…for saving me.”

His stoic expression didn’t change. “Is that all?”

You didn’t want this to be the first and last conversation with the man, so you quickly thought of something to say.

“Why’d you do it?”

He smirked at you, a devious look in his eyes and you felt yourself grow even more attracted to him.

“Because I didn’t want anything to happen to you,” he said and you were surprised at how sweet his words were.

“Not before I did this,” he continued and you felt his lips slam against your own. Your entire body grew warm and you quickly kissed him back, tangling your hands in his hair.

You pulled away to take a shuddering breath in. “You like me?”

“No, I kiss everyone I meet,” he answered, smirking at you.

“I hope that’s a lie,” you said and he shrugged, raising an eyebrow at you.

“And why is that?”

“Because I wanted to thank you the proper way,” you said, gaining some confidence now that you knew he was attracted to you.

You grabbed his hand and pulled him into the nearest room in the hall. The room was empty and you assumed it was a vacant one. You turned towards him once more once you locked the door behind you and he let you push him on the bed.

He could have easily overpowered you, but he didn’t, clearly enjoying watching you in control. You crawled on top of him, straddling his slim hips and leaned down to kiss him again. The kisses became increasingly passionate and you felt a familiar heat pool in your lower abdomen.

You came back up, taking off your shirt and he leaned upwards, too, following your example. His lean body was perfect in your eyes and you felt your excitement grow.

You gently ran your fingertips over his skin and you could have sworn you felt him shudder.

“Sit on the edge of the bed,” you said, standing up from your position and proceeded to take off your pants. “And take your pants off.”

He seemed amused at how dominant you were being, but didn’t question your desires. You took your bra off, staying in your panties and turned to find him sitting there in all his glory, completely naked. You were pleased to find him completely erect and felt proud of yourself for making him that excited.

You kneeled next to him and he looked at you, slightly confused. Apparently, no one had done this for him before.

One of your hands wrapped around his member and you felt him twitch. You started pumping your hand, up and down, and smirked at Loki, who’s eyebrows were furrowed once again and he was biting his lips. His bright blue eyes looked almost black and his pupils were dilated almost completely.

“Really, Loki, thank you for saving me,” you said, in the most seductive tone you could manage.

“You have nothing to thank me for,” he groaned out.

“Of course I do, Loki,” you responded and leaned upwards to take his dick into your mouth. You heard him groan quietly and felt his hands go to your hair to hold you in place. You started to suck gently on it, slowly increasing your speed until he was groaning uncontrollably. You felt empowered that you had made the always in-control Loki into the moaning mess he currently was.

You penis started twitching and you knew he was close, so you released him with a ‘pop’. You leaned back and smirked at him once he focused his eyes on you. He stood abruptly and picked you up roughly, bending you over the table in the room. You felt his hand rub against your cunt through your soaked underwear and you let out a moan. You felt him move the material aside and he quickly entered you from behind.

The sudden intrusion and his size made you groan in slight pain, but you got used to the feeling quickly and when he started thrusting, you moaned in pleasure. One of his hands gripped your waist tightly and the other reached around to rub your clit. The explosion of pleasure in your lower regions made your vision go black and your orgasm came over you unexpectedly.

He continued to thrust, dragging your pleasure further and you felt him groan as he came.

He stepped away from you, his penis sliding out of your wetness. You turned to face him and he was smirking, the devious look in his eye once again. He gave your body a once over.

“I should save your life more often." 

You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules of potential energy—enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.

Why do you have to be different?

​​​​​​​The lake became their ‘spot’, they met each other there almost once a week. Their lives became busy again, Taehyung having to finish his final copy of his part one for his thesis, Tori having to study pretty hard in order to ace her exams (she decided she should try harder this time round considering she was dating the smartest kid in her class) and apart from that Taehyung would often go to the library or to the gym – and only ever during dusk – while Tori would be at the mall with friends or working her part time job at the grocery store.

Science books for space witches

Astronomy - General

Cosmos - Carl Sagan

So, anything by Sagan is kind of a “gimme” but his writing style is absolutely delightful. Cosmos is probably his most comprehensive overview of the 14 billion years of cosmic evolution and covers everything from the origins of life, black holes, stellar evolution, the planets, and space exploration. If you’re going to pick up any book on this list, go for this one. 

Cosmos - Giles Sparrow

This book is fucking GIGANTIC (14″ x 17″!!!) and filled with gorgeous high resolution space photos. I have this book on my coffee table and can spend endless hours just flipping through it and marveling at the beauty of the universe. Well worth the money.

Planets - Giles Sparrow

Another book of high resolution space photographs, this time of the planets in our solar system. 

Origins: 14 Billion Years of Evolution - Neil DeGrasse Tyson

A great overview of our universe, it’s evolution, what we know, and what we don’t know. 

Astronomy - A Self Teaching Guide

This is a book pretty commonly used in Astronomy 101 courses and is a great resource for those wanting to learn more about the science itself on their own. It’s formatted like an easy to read textbook and contains workbook sections to test your knowledge. 

Astronomy 101:  From the Sun and Moon to Wormholes and Warp Drive, Key Theories, Discoveries, and Facts about the Universe

Extremely easy to read book covering a huge breadth of topics. This book doesn’t go terribly in depth on any subject  but it’s great for picking up and reading a bit at a time and  for figuring out what in particular you’re interested in. 

Basic Physics: A Self Teaching Guide

A practical, easy guide to the basic concepts of physics.  Requires no math and easy to understand for “non-science” people. 

Observational Astronomy

Nightwatch: A Practical Guide to Viewing the Universe

This book is a great introduction to stargazing with loads of star maps, information on astronomy equipment, a basic introduction to astrophoography, and information on notable upcoming astronomical events. My personal favorite thing about this book is that it lists objects in the night sky by how they can be viewed - naked eye, binoculars, small telescope, etc. This book includes charts for both the northern and southern hemisphere so it’s applicable no matter where you live. 

50 Things to See With a Small Telescope

In a similar vein, this book is precisely what it sounds like - a guide to cool shit you can see with an inexpensive telescope. The best feature is that it has pictures of how the object will appear through your telescope rather than just illustrations or photos taken with powerful equipment. This makes it much easier to  find the objects in the night sky.

Turn Left at Orion

One of the most popular stargazing books of all time and with good reason. This is pretty THE  beginner’s guide to observational astronomy and gives clear, easy to use information about how to find various objects in the night sky. 

Binocular Highlights - 99 Celestial Sights for Binocular Users

A great guide to star gazing for those of you using binoculars.
