Yeah dude I just HATE knowing how things work! Who the fuck CARES how the Universe will die, or that we don't understand 95% of it SO WHAT. I hate the Universe. And apparently myself since I AM a physicist who's also a woman. GASP. 🙄
Oh Saturn has a hexagon shadow going because of the physics of fluid and shit? SO WHAT. HOW BORING. (NOT)
Amazing work by the wonderful @JPMajor (oops i mean NOT amazing, I'm a woman and therefore in hate this! 🤦♀️)
Oh, and the Universe looks like a cosmic web because of the way that stupid boring stuff you call "dark matter" decided to orient itself and so the stuff we can see fell towards it, because of literally THE MOST BORING THING EVER: PHYSICS?! Pshhhh
(From Millennium Simulation)
AS IF I care that giant clusters of galaxies (that are bound together by this "gravity" crap) bend spacetime so that galaxies behind them that should be blocked are seen as arcs 🙄 BORING. (Wait that looks like a smile... NO. It's boring. I'M A WOMAN DAMMIT)

Oh OKAY so now there's this stuff about quantum mechanics that says stuff *actually does* tunnel through walls. Wait, it can get to Hogwarts?! NO I'M A WOMAN SO I HAVE TO HATE PHYSICS! (Why am I feeling like I really love this stuff?!)
(Drawn by me; I know, BLASPHEMY)
OKAY now I'm supposed to care that this is an image of Saturn's rings, and they look all wavy and stuff because of gravity and orbital mechanics, ie PHYSICS? NAH
(More on my blog post all about Saturn's rings: astropartigirl.com/2017/05/27/sat…)
Image processed by me. I know, blasphemous.
Whoopdeedoo, a wormhole could IN THEORY get me to a place REALLY FAR AWAY in the Universe. Which in itself is boring. I don't care about the idea of being able to see our galaxy from another one!! ... wait, I DO think that's pretty cool... 🤔
(Image from astronomy.com/news/2019/07/i…)
SO WHAT that there are these things called black holes that NOTHING, NOT EVEN LIGHT can escape from?! And some were formed from dying stars, while ginormous ones at the centers of galaxies we don't even understand how they were created? And there's one in OUR galaxy? MEH
(LIGO)
Wait, so you're saying that stuff like time travel that I love to watch on my favorite shows like Doctor Who actually have some physics behind it, even if it might not work in practice (or might)? BOO, HOW BORING TO THINK OF HOW WE COULD MAKE IT A REALITY. Wait a sec...
So, none of the stuff I mentioned above is ACTUALLY BORING, and I ACTUALLY LOVE IT. Could it be that WOMEN ACTUALLY DON'T HATE PHYSICS?!! 😱 SHOCKING. What's even MORE shocking is that I had to write a thread about it, because people still believe women hate physics. In 2021. 🤦♀️

Just learned of cliquey exclusionary stuff going on where specific accounts were boosted for followers, and others left in the dust. Some personally hurt. I'm one of the scicommers "left in the dust", had no idea, but here are my thoughts since I'm part of "Science Twitter":
I wanted you all to know I had no idea, was not included in the group. I worked VERY hard on my following with my scicomm for years, with no luxury of a group boosting me. I DID notice accounts (that happen to be part of this fiasco) gain a significant following.
I didn't get it since I was producing great content (imo). Wondered what I was doing wrong, felt inadequate, less important. And quite frankly, worthless in Twittersphere. Didn't understand how accounts who haven't done what I have for as long as me, earned followings I did not.
If you touch two CLEAN blocks of the same metal together in space, they weld!
Atoms in solid metals move a bit. Touch two clean surfaces together, and the atoms can't tell they're in different blocks so they become one group of atoms, ie ONE SOLID.

The reason it doesn't happen on Earth when you put two of the same metals together is because of oxygen, which causes metal to rust. That oxide layer sits the two metal surfaces, so atoms in each block see a layer of different atoms, and know that's their "limit" for movement.
If you're wondering if this has affected space missions, it has! The Galileo space probe sent to Jupiter couldn't deploy its high gain antenna on the way to Jupiter because the metal rods that were to open up the "umbrella" got cold welded together!

"If dark matter exists, why can't we see its effects in the solar system?" is a question I'm often asked. The answer: compared to the mass of the Sun, the mass of dark matter in our solar system is far too little to affect planet orbits like it does stars in galaxies. Here's how:
The solar system is big--REALLY big--from our perspective. But it's a tiny speck on the galactic scale. We can *very roughly* say there's ~1 star per pc³ in the galaxy (1 pc = 3.26 light-years). To compare, our solar system is ~100 AU in radius, which is only about 0.0005 pc.
So our entire solar system is just a tiny speck on the galaxy! There's *way more space* between stars than you'd think. (Of course near the center of the galaxy stars are very densely packed due to gravity, and very sparse in the disk region).

The list goes on. And the Nobel Prize committee still won't admit sexism is why there have been 3 women to win in physics, and 5 in chemistry, EVER. Great start to 2020 with this one.
Of 212 Nobel Laureates in Physics (one man was awarded *twice*, btw), 3 have been women = 1.4% Nobel Laureates in Physics are women.
Of 184 Nobel Laureates in Chemistry, 5 went to women = 2.7% Nobel Laureates in Chemistry are women.
The numbers speak for themselves, friends.
And don't get me started with Vera Rubin. She literally ushered in a new era of dark matter physics. Her work was published 1976, and she lived till December 2016. That's 40 YEARS the Nobel Prize committee had to award her, and snubbed her *every single time*.
Fun fact: the circumference of a circle in our spatially flat Universe is 2πr. But if our Universe was positively curved (think the surface of a sphere), it's *less than* 2πr. If negatively curved, like a saddle or pringles chip for example, it's *greater than* 2πr!
It makes sense too if you picture it: on a sphere, the circumference of a circle of the same radius as a circle on flat space will be smaller because the sphere curves inward, making the path you travel that circle to be shorter than the one on a flat sheet of paper.
Now do the same on a pringles chip: the path you travel along the circumference is *longer*. Imagine a sheet that's kinda wavy around a point, and you draw a circle around that point. that's *kinda* like negatively curved spacetime, so a circle would have a larger circumference.
The Nobel Prize in Physics awarded was very well-deserved. However, next time you hear Vera Rubin didn't win for discovering dark matter bc *insert excuse here*, let today show exactly why she didn't win for discovering one of cosmology's most pressing questions: she was a woman.
Today, countless physicists and astronomers chug away at trying to figure out what dark matter is. Myself included. We all owe part of our curiosity and drive to Vera Rubin. Vera Rubin. Remember her: Vera Rubin. Because she's why you do what you do. And she didn't win the Nobel.
And let today show you that "waiting till next year" wasn't even necessary. For the Nobel Prize in Physics could've just as well been awarded to more than one discovery as it was today. But it wasn't because Vera Rubin was. A. Woman. That's it.
