Since it's shaping up to be a tumultuous Pride Month remember:

If they don't want us throwing parties, we can always go back to throwing bricks.

[tehgvicious]

Remember, the first Pride was a riot. Thank you, Marsha. 🖤

do not forget the patron saint of these weeks that we celebrate ourselves proudly and openly in the streets

her name was Marsha P Johnson, and we have her to thank for so much.

remember, the first Pride was a riot, and she was one of the brave souls who endured it to help carve the path which so many of us walk today. she helped found several activist groups regarding LGBT safety and wellbeing. and she was absolutely radiant, too.

thank you, Marsha. we remember you.

As a born & raised Georgia girlie, I cannot emphasize this enough. I learned to hate cops before ACAB was a thing.

I walked out of that movie theater thirsty, y'all.

How people only wanted a picture with Thor and not HIM when he looked this good is insane ….. 💚

[tehgvicious]

Inshallah they find him.

I read through all of this only to wonder: If the light spectrum contains more than what we can see, does that mean we're all technically some level of color blind?

Seeing the Invisible Universe

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, beyond which no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as it skims by the black hole. You might wonder — if this Tumblr post is about invisible things, what’s with all the pictures? Even though we can’t see these things with our eyes or even our telescopes, we can still learn about them by studying how they affect their surroundings. Then, we can use what we know to make visualizations that represent our understanding.

When you think of the invisible, you might first picture something fantastical like a magic Ring or Wonder Woman’s airplane, but invisible things surround us every day. Read on to learn about seven of our favorite invisible things in the universe!

1. Black Holes

This animation illustrates what happens when an unlucky star strays too close to a monster black hole. Gravitational forces create intense tides that break the star apart into a stream of gas. The trailing part of the stream escapes the system, while the leading part swings back around, surrounding the black hole with a disk of debris. A powerful jet can also form. This cataclysmic phenomenon is called a tidal disruption event.

You know ‘em, and we love ‘em. Black holes are balls of matter packed so tight that their gravity allows nothing — not even light — to escape. Most black holes form when heavy stars collapse under their own weight, crushing their mass to a theoretical singular point of infinite density.

Although they don’t reflect or emit light, we know black holes exist because they influence the environment around them — like tugging on star orbits. Black holes distort space-time, warping the path light travels through, so scientists can also identify black holes by noticing tiny changes in star brightness or position.

2. Dark Matter

A simulation of dark matter forming large-scale structure due to gravity.

What do you call something that doesn’t interact with light, has a gravitational pull, and outnumbers all the visible stuff in the universe by five times? Scientists went with “dark matter,” and they think it's the backbone of our universe’s large-scale structure. We don’t know what dark matter is — we just know it's nothing we already understand.

We know about dark matter because of its gravitational effects on galaxies and galaxy clusters — observations of how they move tell us there must be something there that we can’t see. Like black holes, we can also see light bend as dark matter’s mass warps space-time.

3. Dark Energy

Animation showing a graph of the universe’s expansion over time. While cosmic expansion slowed following the end of inflation, it began picking up the pace around 5 billion years ago. Scientists still aren’t sure why.

No one knows what dark energy is either — just that it’s pushing our universe to expand faster and faster. Some potential theories include an ever-present energy, a defect in the universe’s fabric, or a flaw in our understanding of gravity.

Scientists previously thought that all the universe’s mass would gravitationally attract, slowing its expansion over time. But when they noticed distant galaxies moving away from us faster than expected, researchers knew something was beating gravity on cosmic scales. After further investigation, scientists found traces of dark energy’s influence everywhere — from large-scale structure to the background radiation that permeates the universe.

4. Gravitational Waves

Two black holes orbit each other and generate space-time ripples called gravitational waves in this animation.

Like the ripples in a pond, the most extreme events in the universe — such as black hole mergers — send waves through the fabric of space-time. All moving masses can create gravitational waves, but they are usually so small and weak that we can only detect those caused by massive collisions.  Even then they only cause infinitesimal changes in space-time by the time they reach us. Scientists use lasers, like the ground-based LIGO (Laser Interferometer Gravitational-Wave Observatory) to detect this precise change. They also watch pulsar timing, like cosmic clocks, to catch tiny timing differences caused by gravitational waves.

This animation shows gamma rays (magenta), the most energetic form of light, and elusive particles called neutrinos (gray) formed in the jet of an active galaxy far, far away. The emission traveled for about 4 billion years before reaching Earth. On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole detected the arrival of a single high-energy neutrino. NASA’s Fermi Gamma-ray Space Telescope showed that the source was a black-hole-powered galaxy named TXS 0506+056, which at the time of the detection was producing the strongest gamma-ray activity Fermi had seen from it in a decade of observations.

5. Neutrinos

The emission traveled for about 4 billion years before reaching Earth. On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole detected the arrival of a single high-energy neutrino. NASA’s Fermi Gamma-ray Space Telescope showed that the source was a black-hole-powered galaxy named TXS 0506+056, which at the time of the detection was producing the strongest gamma-ray activity Fermi had seen from it in a decade of observations.

Because only gravity and the weak force affect neutrinos, they don’t easily interact with other matter — hundreds of trillions of these tiny, uncharged particles pass through you every second! Neutrinos come from unstable atom decay all around us, from nuclear reactions in the Sun to exploding stars, black holes, and even bananas.

Scientists theoretically predicted neutrinos, but we know they actually exist because, like black holes, they sometimes influence their surroundings. The National Science Foundation’s IceCube Neutrino Observatory detects when neutrinos interact with other subatomic particles in ice via the weak force.

6. Cosmic Rays

This animation illustrates cosmic ray particles striking Earth's atmosphere and creating showers of particles.

Every day, trillions of cosmic rays pelt Earth’s atmosphere, careening in at nearly light-speed — mostly from outside our solar system. Magnetic fields knock these tiny charged particles around space until we can hardly tell where they came from, but we think high energy events like supernovae can accelerate them. Earth’s atmosphere and magnetic field protect us from cosmic rays, meaning few actually make it to the ground.

Though we don’t see the cosmic rays that make it to the ground, they tamper with equipment, showing up as radiation or as “bright” dots that come and go between pictures on some digital cameras. Cosmic rays can harm astronauts in space, so there are plenty of precautions to protect and monitor them.

7. (Most) Electromagnetic Radiation

The electromagnetic spectrum is the name we use when we talk about different types of light as a group. The parts of the electromagnetic spectrum, arranged from highest to lowest energy are: gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. All the parts of the electromagnetic spectrum are the same thing — radiation. Radiation is made up of a stream of photons — particles without mass that move in a wave pattern all at the same speed, the speed of light. Each photon contains a certain amount of energy.

The light that we see is a small slice of the electromagnetic spectrum, which spans many wavelengths. We frequently use different wavelengths of light — from radios to airport security scanners and telescopes.

Visible light makes it possible for many of us to perceive the universe every day, but this range of light is just 0.0035 percent of the entire spectrum. With this in mind, it seems that we live in a universe that’s more invisible than not! NASA missions like NASA's Fermi, James Webb, and Nancy Grace Roman  space telescopes will continue to uncloak the cosmos and answer some of science’s most mysterious questions.

This is high art.

Oh, okay. I see. You think this has nothing to do with you. You go to your closet and you select out, oh I don’t know, that gaslight gatekeep girlboss meme, for instance, because you’re trying to tell the world that you think modern feminism has been co-opted by corporations. But what you don’t know is that that meme is not from Instagram, it's not from Twitter, it's not from Tiktok, it’s actually from Tumblr. You’re also blithely unaware of the fact that in January 2021, Tumblr user missnumber1111 posted, "today's agenda: gaslight gatekeep and most importantly girlboss." And then I think it was a-m-e-t-h-y-s-t-r-o-s-e, wasn’t it, who reblogged it with an image of the phrase edited over a piece of "Live, Laugh, Love" wall art? And then gaslight gatekeep girlboss showed up in the feeds of eight different Twitter repost accounts. Then it filtered down through Instagram and then trickled on down into some tragic “alt side of Tiktok” where you, no doubt, fished it out of some clearance bin. However, that meme represents millions of notes and countless Tumblr users and so it’s sort of comical how you think that you’ve made a choice that exempts you from Tumblr when, in fact, you’re wearing the meme that was selected for you by the people in this room. From a pile of “stuff.”

#so sad, but oh so pretty

[tehgvicious]

I'm lying in bed at a hotel in France, kind of dreading the flight home to the U.S. tomorrow.

On one hand, I miss my cat.

On the other, I feel like politically, financially, even safety, shit's about to crash.

But I had a wonderful moment in Paris. We ran into some kids (20+ years old) and when I said I was American thezmy said, "Oh... Trump?"

I made the most pained face I can conjure and said "NO. Fuck Trump."

They cheered. One of them asked if I was going back. I said I probably would and then said if things get bad I have an exit plan.

In Marseille, I've seen a lot of street art that says "Free Palestine."

It's wild to me that I feel more supported by foreign countries than my own.

It's honestly been so heart warming to see the support from the French people. But I can't help but dread what I'm coming home to.

Anyway.

Fuck Trump, the Republicans and the entire administrstion. Fuck the system, fuck the man. Imma come home and fight, I guess.

I think they knew what they were doing, putting him in a suit and glasses and those mischievous little curls. I see y'all.
