oh man I'm asking for trouble. LOKI, TIME LOOP/TIME TRAVEL

An adolescent Loki, still a century or so short of his majority, discovers a time travel spell in a forbidden grimoire, and desperately wishes to try it. Of course, time magic is illegal, so he has to be cautious; he ultimately chooses to go down to Midgard to test the spell, since it’s a backwater realm and not densely populated. It’s a fair place for a test run, and one where he’s unlikely to cause a paradox by running into his future self – after all, what possible reason would he have for wanting to go to Midgard?

Of course, the premise of the spell is imperfect. It’s theoretical, and has never worked. But in his studies, Loki thinks he finds the problem – the key to making it functional. So he modifies the enchantment. 

But the spell exists in a kind of quantum uncertainty, where casting it creates a bifurcated timeline; in one branch he succeeds, and leaves the timeline; in the other he does not, and remains in his present.

Loki however, wants to discover what destiny lies in store for him, and the exploits of his future self. Traveling to a future in a world he hasn’t occupied is useless to him – so he modifies the spell even further, to forcibly merge the timelines.

Unfortunately, this creates a massive quantum instability of a universe where there are two Lokis, and where the spell simultaneously failed and succeeded (The one Loki who time-traveled, and the other Loki who only remembers the spell not working and getting yelled at for a long time for trying when the Allfather found out).

And of course, the younger Loki – the one who traveled – is now on Midgard in the modern day, and is attacked and taken into custody by the Avengers for reasons he doesn’t understand.

It’s a strange and terrifying future, and he is beginning to have regrets. But he manages to convince the Midgardians that he isn’t who they think he is once Thor of all people turns up. Why his brother’s future self is spending time on Midgard, Loki also can’t fathom, but he’s relieved to see him all the same.

And Thor…

Thor’s heart is swelling and breaking all at once as the truth emerges, because this is the brother he remembers. This is his Loki; before it all went wrong. And now his friends can see how his brother once was, when he was witty and clever and hadn’t been lost to madness and cruelty.

But the Loki who has been lost – the mad and cruel Loki – is still at large. There are two Lokis now: past and present, and their simultaneous existence is weakening the fabric of reality. All too quickly, younger!Loki realizes that he can’t go back, either – if he goes back to the origin point of the spell, that conscious version of him will cease to exist as the timelines collapse, and only the version who grew into the Loki-who-fell will remain. 

And Loki doesn’t want to stop existing; doesn’t want to die

But the universe is tearing itself apart. There can only be one Loki. And so he comes up with a plan.

Loki is going to kill his other self.

Neutron star smash-up shows us first light alongside a gravity wave

For the first time ever we’ve detected light from a gravitational wave event, after two incredibly dense neutron stars smashed together, an exciting discovery that  helps scientists understand some of the most violent and powerful collisions in the universe. 

Neutron stars are the crushed remnants of massive stars which exploded as supernovas. What used to be the core lingers behind as the smallest and densest stars in our universe, a ball just a few miles across but containing more mass than our Sun. Just one teaspoon’s worth of neutron star would weigh a billion tonnes. 

Earlier this month the Nobel prize in Physics was awarded for the first detections of gravity waves, ripples through spacetime. But those waves were caused by black holes merging and so no light, or electromagnetic radiation, was observed because famously light can’t escape black holes. 

Astrophysicists believed that when two neutron stars collided there would be visible light alongside gravity waves, as predicted from Einstein’s theories. But until they saw it happen, no-one knew for sure. 

On August 17 2017 this all changed. 

Not only were were gravity waves picked up from a galaxy 130 million light years away, but so were range of light-based measurements from the merger of two neutron stars as they smashed together.  

These included a burst of gamma rays, light from a type of radioactive explosion called a kilo-nova and, later, X-rays from the gamma ray burst afterglow. 

Thousands of scientists around the world have been working furiously ever since to present the initial findings, published today. 

Together these measurements confirm a host of theoretical predictions, and will greatly advance our understanding of what exactly goes on when these incredible events occur, such as the conditions in which some of the heaviest elements including gold and platinum, are formed.

In one sense the we’ve been lucky to capture all this data in such rich detail because we could have been waiting decades for a neutron star merger close enough to Earth to be detected. But, on the other hand, scientists have been working for decades to get to the point where we have good enough equipment to be able to make the most of it. It’s a case of chance meeting preparation, and it’s paid of for the scientific community.

Dear D&Diary,

Today I had the revelation that my half orc has 30ft speed, but because she’s a monk, her unarmored movement is +10ft at Level 3. Using the ki feature Breath of the Wind, she can dash as a bonus action meaning she can go 80ft in a turn.

If anyone cast Haste on my dear sweet Marfu, she would go 160 in six seconds. 

At her most perfect Level 20 self’s unarmored movement of +30, she could go a max 120ft in a turn, or 240ft hasted. With 20 ki points to spend that could mean a solid two minutes of going almost 30 miles per hour and I think that’s beautiful.

13.05.17 // Updated my physics window for the first time in ages! Had some thoughts over the past few weeks surrounding a free scalar field universe model so I drew them up as well as some old game theory because I watched a Beautiful Mind and felt nostalgic. I hope you are all having wonderful days / evening / whatever plane of existentialism you currently observe 😉

I keep on seeing people throw around the term “multiverse theory” and I don’t think anyone fully grasps the true meaning on it.

The multiverse theory speculates that there are an infinite number of universes to correlate with an infinite number of possibilities. Infinite by definition means “all”. Multiverse theory doesn’t hold “most” possibilities within it’s infinite universes. It holds, all possibilities.

Meaning somewhere out there in the cosmos there is a version of Earth much like our own, where Naruto and Cloud Strife are in a homosexual relationship and have a son, John Cena, and they are all the presidents of the United States of Gondor.

If you put any stock in the multiverse theory then you must concede that this is not only a possibility, but a stone cold fact. This is why theoretical physics is the most brilliant scientific discipline.

yes, i can stick magnets on my arm.

but i only do it for a good cause. the letters are magnetic. repainting the arm is too much work

steve decided he wanted to draw this because the last time i did something like this there wasn’t anything to prove it had happened. (last time i painted ‘die nazi scum’ on the side of a tank which id stolen from the nazis. the 40s were a wild time my friends)

When you think you’re all alone.

When you think nobody loves you.

When you think everything is dark and rotten and there is only sorrow.

You do not know.

You do not know that all around you

in the darkness

there are ninjas.

Not one. Not ten.

Dozens of ninjas.

They feel your pain.

Dozens of ninjas that you do not see.

In the shadows. In the ceiling.

Under the cushions of the couch. They cry beside you.

They wish you well.

As a consequence people who dislike 👎 the Rick and Morty dipping sauce truly ARE idiots 😖 - of course they wouldn’t appreciate 😶, for instance, the taste in Rick’s existencial fascination 👀👃 with the sauce 🙀, and his catchphrase 💬 when consuming said sauce, “Wubba Lubba Dub Dub,” 😢💔      which itself is a cryptic reference to Turgenev’s Russian 🇷🇺 epic Fathers and Sons 📔.

Hello everyone.

Apologies for the long/unexplained absence. I’ve not been doing very well recently and I haven’t quite had the time to be posting. However, a small update is that I’m struggling very much with my mental health but my studies are going very well. I just wanted to thank you all for your kindness and support and I will try update more regularly from now on!

I hope you are all well and looking after yourself, and I’m sending love, hugs and good study vibes 💗

The quest to crystallize time
Bizarre forms of matter called time crystals were supposed to be physically impossible. Now they’re not.

Christopher Monroe spends his life poking at atoms with light. He arranges them into rings and chains and then massages them with lasers to explore their properties and make basic quantum computers. Last year, he decided to try something seemingly impossible: to create a time crystal.

The name sounds like a prop from Doctor Who, but it has roots in actual physics. Time crystals are hypothetical structures that pulse without requiring any energy — like a ticking clock that never needs winding. The pattern repeats in time in much the same way that the atoms of a crystal repeat in space. The idea was so challenging that when Nobel prizewinning physicist Frank Wilczek proposed the provocative concept1 in 2012, other researchers quickly proved there was no way to create time crystals.

But there was a loophole — and researchers in a separate branch of physics found a way to exploit the gap. Monroe, a physicist at the University of Maryland in College Park, and his team used chains of atoms they had constructed for other purposes to make a version of a time crystal2 (see ‘How to create a time crystal’). “I would say it sort of fell in our laps,” says Monroe.

And a group led by researchers at Harvard University in Cambridge, Massachusetts, independently fashioned time crystals out of 'dirty’ diamonds3. Both versions, which are published this week in Nature, are considered time crystals, but not how Wilczek originally imagined. “It’s less weird than the first idea, but it’s still fricking weird,” says Norman Yao, a physicist at the University of California, Berkeley, and an author on both papers.
