When you stack carbon nanotubes on their ends and squish them together, you get a material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black. Scientists are really excited about the potential applications of the substance; since virtually no light is “wasted”, it would be used to improve optical tools like telescopes, and even be used to make nearly 100% efficient solar collectors.
9. The Most Flammable Substance
Chlorine triflouride is terrifyingly flammable, to the point that the Nazis deemed it too dangerous to work with. When people who consider genocide their life’s goal don’t want to use something because it is too deadly, it bears treating it with some caution. There is a story that a ton of the stuff was spilled once and caught fire, and it burned through 12 inches of concrete and another meter of sand and gravel before going out.
8. The Most Toxic Poison
What do people inject in their faces? The world’s deadliest poison. Botox uses botulinum toxin, produced by the bacteria Clostridium botulinum, and it is so deadly, an amount equal to a grain of salt is enough to kill a 200 lb man. In fact, they even suggest that it would only take 4kg, properly dispersed, to kill every last person on earth.
7. The Hottest Substance Ever
By smashing gold atoms together at nearly the speed of light,you get a quark-gluon soup, and it reaches 4 trillion degrees Celsius, a mere 250,000 times hotter than the inside of the sun. The amount of energy released in the collision was sufficient to melt protons and neutrons, which in itself could be featured on a list of things you never even knew were possible. Scientists think this substance could give us an idea of what the birth of our universe was like, so it’s good to see they aren’t just creating tiny supernovas for the fun of it. However, the really good news is that the soup was only a trillionth of a centimeter across, and only lasted for a trillionth of a trillionth of a second.
6. Most Acidic Acid
Fluoroantimonic acid is 21019 times more powerful than sulphuric acid, and can even eat through glass. And it explodes when exposed to water. And when it is reacting, it gives off poisonous fumes that can kill everyone in a room.
5. The Most Explosive Expolosive
This particular honor is actually currently shared between two compounds; HMX and Heptanitrocubane. Heptanitrocubane mostly exists in labs, and is similar to HMX, but has a denser crystal structure, giving it greater destructive potential. HMX, on the other hand, exists in quantities large enough to be physically threatening. It is used in solid rocket fuel, shaped charges, and even nuclear weapon detonators.
4. The Most Radioactive Substance
Polonium-210 is so radioactive, it glows blue. A former soviet spy, Alexander Litvinenko, was duped into consuming some without his knowledge, and he died of cancer shortly thereafter. This is not that kind of thing you ever want to mess with; the glow is caused by the air around it being excited by the radiation, and it can actually heat objects nearby. If the fact that something highly radioactive gives off heat, keep in mind that when we usually think “radiation”, we are thinking of things like a nuclear reactor or explosion, where an actual fission reaction is happening.
3. The Hardest Substance
If you thought the hardest substance on earth was diamond, that was a good, if inaccurate guess. It is technically an aggregated diamond nanorod. It is actually a collection of nano-scale diamonds, and it is the least compressible, hardest substance known to man. It was developed in Germany in 2005 and will likely be used in the same capacity as industrial diamond, except will be more wear-resistant than regular diamonds.
2. The Most Magnetic Substance
The substance, developed in 2010 out of iron and nitrogen, is 18% more magnetic than the previous record holder, and is so powerful, it has forced scientists to revisit how magnetism works. The man who discovered the substance has taken great pains to ensure that his work can be reproduced by other scientists, because a similar compound was reported developed in Japan back in 1996, but other physicists could not replicate it, so it was never officially accepted.
1. The Most Super Superfluid
Superfluidity is a state of matter (like solid or gaseous) that occurs at extremely low temperatures, has high thermal conductivity (every ounce of it is always exactly the same temperature), and no viscosity. Helium 2 is the “most” example of this. A cup of He2 will spontaneously flow up and out of a container, as if it just decided to leave. It also seeps right through otherwise solid materials because its complete lack of friction allows it to flow through otherwise invisible holes that would not allow regular helium (or water for that matter) to flow through. He2 did not wind up at number 1 just because of its ability to act like it has a mind of its own, though, it is also the most efficient thermal conductor on earth; several hundred times that of copper. Heat moves so fast through Helium 2 that it moves in waves, like sound (and is fact known as “second sound”), rather than dispersion, where it simply transfers from one molecule to another. Incidentally, the forces governing He2’s ability to crawl walls is called “third sound”. You can’t get much more extreme than a substance that required the definitions of 2 new types of sound.
“Except you can’t show a topless woman on TV - and you can’t defibrillate a woman in a bra. So victims of heart attacks on TV are *always* male. Did you know that a woman having a heart attack is more likely to have back or jaw pain than chest or left arm pain? I didn’t - because I’ve never seen a woman having a heart attack. I’ve been trained in CPR and Advanced First Aid by the Red Cross over 15 times in my life, the videos and booklets always have a guy and say the same thing about clutching his chest and/or bicep.
And people laugh when I tell them women are still invisible in this world.”—
When “Pokemon” was first released in Japan, there was an odd phenomenon between children ages 7-12, particularly in those using headphones to listen to the sound effects. Increase of nosebleeds, irritability, insomnia, and addiction to the game, playing for hours and hours on end and crying to the point of vomiting when the opportunity was taken away.
Roughly 70% of these cases ended in suicide.
In almost every case of the aforementioned symptoms, despite gameplay time recorded to the limit of the internal clock, the game had not progressed further than “Lavender Town”.
A closer analysis of the game revealed a tone in the audio of the music for “Lavender Town” at a pitch undetectable by fully developed human ear drums. Within weeks every unsold copy of the “first edition” the game were recalled silently and the game was re-released with re-mastered audio for “Lavender Town”.
The widely known version is said to be missing three extra tones, as well as the unique, binaural tone of the first edition, although this is unconfirmed due to the rarity of working first edition copies; in the known few that remain, the internal clock and ‘battery save’ have all timed out and ceased function, and in many cases the game will freeze upon entering any battle.
The audio post above is the original file that was heard by these children.
at recess in 5th grade someone asked me “is your refrigerator running?” and i said yes and they said “then you better go catch it!!!” and i screamed and started crying and ran to the bike rack and got on my bike and rode back home but my refrigerator was still in the same place and i didn’t understand why anyone would scare me like that
