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

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.

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.

Beat Zone 15000. 2 more beat zone achievements and 14 more total.

Pokemon Sleep

S rank for the week. I knew that this week would be crazy hot and I I was going to have trouble sleeping so I sorta cheated. Tracking my sleep wasn't going to be really helpful since I knew it was just gonna be bad so I let my PoGo++ rest on my nightstand for a bit before putting it back on the bed.

Final Fantasy V

Just about at the end of my 3rd run. Trying to decide if I want to attempt the super bosses. I don't actually like the team composition that much (Dragoon, Mystic Knight, Black Mage, Red Mage) so I don't really want to.

The Land

Finished up the series. I think I enjoyed book 8 when I read it the first time but rereading it I found it was so boring.

Went to read other reviews on it and one resonated with me. It basically said this. They spent so much time building up to this huge battle. During/after the battle we get so many hints of boons for the village. And the main character gets thrown down a hole so we can't see any of the village growth. Instead, we literally get a whole chapter of diarrhea.

System Universe

Started reading a new series.

Seems pretty okay so far. The beginning was very much whiplash from reading the summary to reading the first chapter but it leveled out pretty quickly.

My favorite punishment for OG Luo Binghe is just giving him Shen Yuan

Like he is used to getting any woman he wants under him, but then here comes a man that provides him with emotional stability, but also doesn't have sex with him. Not because he doesn't want to, but because he can't pick up on the hints Bingge is dropping, and even if he does, he will pretend not to see them because he thinks Bingge is 100% straight

He is in a purgatory of head pats and constant blue balls

Shen Qingqiu was doomed.

He stood still, fluttering his fan nervously and trying to avoid catching his counterpart's, the real Shen Qingqiu, glaring eyes from across the room. Instead, he idly observed the other Cang Qiong Mountain Peak Lords, trying to spot the differences between the ones he knew and their alternates.

Liu Qingge had brought back a strange artifact from one of his hunts to the monthly Peak Lord meeting. It was a mirror, rimmed an ugly tarnished gold, topped with a decoration that was shaped into an unidentifiable creature with ruby red eyes.

[Important Artifact Detected: Red-Eyed Sphinx's Mirror! Quest starting...]

Shen Qingqiu had been trying to remember where it might have appeared in PIDW when the surface of the mirror suddenly began to glow a dull yellow. It quickly brightened until it obscured everyone's vision.

And then, there stood another set of peak lords across the room, facing them down.

System, what on earth is going on???

[Quest started: Lost Long Spirit in My Reflection! Other characters have been transported to this universe. Host must find a way to send them back without revealing his identity as a transmigrator.]

WTF? I didn't agree to this!

[Good luck!]

System??? Get back here!

While the two Yue Qingyuans and Xu Qinglis conversed together to try to understand what had happened, the other peak lords had begun to mingle with each other, curious about their counterparts.

Shen Qingqiu tried to suppress his panic, sticking close to Shang Qinghua. His Yue Qingyuan occasionally flicked his softened gaze towards the alternate Shen Qingqiu, likely noticing that the other still acted as he used to before his qi deviation. In fact, several of the peak lords he had gotten to know over the years were sending some looks at the other Shen Qingqiu.

With the original goods right there, how long would it be before something exposed him as a fraud?? What if he was confronted about why he acted so differently?

[Host must avoid having his identity exposed. Being revealed as a transmigrator will result in Host being immediately sent back to his old body.]

Yeah, yeah, same shit as always!

Looking to his side, Shang Qinghua seemed to be experiencing the same threats, desperately looking away from the more dead-eyed Shang Qinghua across the room who, luckily, was barely paying him any attention.

Fuck, what do we do?

---

Shen Qingqiu continued to glare at the Other Shen Qingqiu in the room. The other Shen Qingqiu was so obviously a fraud, he could tell within minutes of being here. While his alternate seemed somewhat familiar, he didn't act like him at all, his mannerisms were all off, and despite the attempt at keeping a poker face, Shen Qingqiu could tell that he was nervous. Probably at being caught out.

His alternate self had likely been replaced with a bodysnatcher or some sort of spirt, if they truly were supposed to be the same person. Was everyone else stupid, or had they had their brains sucked out by a Heart Mouthed Lobster-Squid?

Or maybe they simply like the bodysnatcher better and didn't bother to investigate.

Shen Qingqiu's face became stormier, turning his glare to the Other Yue Qingyuan, wondering if he had felt happier once his precious Xiao-Jiu had vanished. The other Yue Qingyuan's face grew even more pathetic. Tch. Typical.

"That stupid System--" Shen Qingqiu nearly snapped his neck in looking at the bodysnatcher upon hearing his murmur. The fraud, upon noticing his sudden attention, clammed back up and looked away. But Shen Qingqiu knew what he heard.

Xi Tong.

He hadn't heard those words in years, not since--

He stepped forward, scanning the other once more. Upon a second, more thorough look, Shen Qingqiu realized that he grew more familiar. He wore his hair in the way that Shen Qingqiu wore it, but looser and less severe. His eyes were clearer and lighter, with hints of a smile, despite his nerves. He occasionally quickly glanced up and to his left, as if seeing something there, before bringing his attention back to the room at large.

No. It couldn't be. He was long dead, despite Shen Qingqiu's best efforts. Even if the fake had some similar things about him, that doesn't mean--

Shen Jiu had once had a brother, besides Qi-ge. Slightly smaller than him, despite the fact that Shen Jiu passed him along as much food as he could when on the streets. He smiled so much despite their circumstances, and was so kind despite Shen Jiu constantly telling him that he was making himself a target. But he looked so, so similar to Shen Jiu himself. They could have switched their clothes and looked exactly the same, if one didn't notice the difference in their demeanors.

His brother has also always been a little odd, talking to himself and arguing with an imaginary friend that only he could see named Xi Tong. One of the reasons that they survived as long as they did on the streets was due to the inexplicable knowledge that his brother seemed to have. Somehow, his brother knew about the various plants or small animals that they could hunt and sell for a pretty coin in the markets. Shen Jiu never asked, not looking a gift horse in the mouth.

But his brother was dead. He had died years ago, in the time during when they were in Qiu's manor. During a punishment for Shen Jiu's attempt to get them both to join Wu Yanzi; he had switched their clothes and taken Shen Jiu's place and died for it. That had been the final catalyst that made him set the manor ablaze and escape, mourning his brother's death as his fault for daring to be free. Cursing Qi-ge for not coming back for them.

Dazed and his vision dim, Shen Jiu took another step forward, and another. Hope, something he thought he had killed off long ago, slowly rose in his chest.

Had his brother survived in this world? Had he managed to escape alongside Shen Jiu? Or had Shen Jiu died in his place? Dimly, he can't help but think that the world would be far kinder if that were the case. If his brother had made it to Cang Qiong Mountain and became a peak lord all on his own and still managed to keep his smile. If he didn't have Shen Jiu dragging him down with him.

The other Shen Qingqiu, not having noticed his approach, laughed at something the other Shang Qinghua said ("Wonder if Shang Qinghua is a traitor here, too," Shen Jiu thought dimly). His laugh was the same. He rose his fan to hide his face, but Shen Jiu noticed how his nose crinkled, and his eyes nearly closed in delight, exactly like--

"A-Yuan?"

The baby god.

The world was in panic as Justice League couldn't do anything, a glowing green metorite ball the size of Neptune was heading directly toward Earth.

The green lantern corps couldn't do anything to move the direction of the metorite, Superman couldn't even get near without feeling faint, believing that there was kyptonite on the metorite stopping him.

Not even John could make any deal that involved that metorite at all.

Many city panic, started fighting, crying, and broken down. Many religious groups accept their fate.

Gotham City refused to go out quietly as everyone was throwing a simultaneous party. Even the villains went all out, even Joker didn't cause harm to anyone, much less made a joke at all..

Joker tremblingly held a very old playing joker card that Batman had since their first fight years ago while his eyes, one still black from earlier look to the last live being recorded with Batman's voice speaking on the live, He stayed along side in gotham even when end of the world was here.

Clark Kent stayed with his ma and pa house, lois Lane, holding her hands.

The world stood still as the seemingly the end was close by.

Only for the glowing green metorite was rapidly slowing down, nearly the same length by as the moon even if it was gigantic in comparison.

A gargantuan hands seen to have grasped it, the hands itself were covered in stars and dust as a loudest chirp could be heard around the earth.

Bright bluish green eyes the size of the sun slowly blink with curious, a gigantic toddler the twice size of Jupiter, a chubby face covered in dwarfs star made freckles, a glowing green necklace that held the tiny dwarf pluto, hair the covered Most of the darkness that was the night sky like strains clouds made from the heaven themselves.

A massive deep blue puff escaped the gargantuan being's mouth, raining down all over the earth, where tiny pure crystalized ice was the size of a baby pearl that never melted.

Everyone who was watching the live or was watching outside could see the being clearly.

The metorite threatened to end all life on earth as they knew it was stopped by a god.

The god slowly turned, the bright white hair swaying star dust everywhere in the sky as they were turning to someone and floated away, the joyous young laughter of a toddler echoing on earth.
