There’s more to our wonderful world than any single person could ever know. When one Reddit post asked people to share facts that they thought nobody else knows, the rest of us got a great list of curiosities from around the world.

Did you know, for example, that dolphins can be trained to perform military aquatic guard duty? Or that grass only evolved once dinosaurs were practically extinct? There are plenty more fascinating facts in this list, so scroll on and learn something new!

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Sarah Winchester (who built the “Winchester Mystery House”) was not into the occult, wasn’t afraid of evil spirits, and didn’t think she could live forever by continuing construction of her house - or, at least there is no evidence to support that. People who knew her said she was a devout Christian and would never have anything to do with the occult. The stories about spiritualism and paranoia are for the tourists. She probably just liked having workmen around and a little activity going on at the house - she was one of the richest women in the world, so she could do as she pleased. Some who knew her said she may have done it to keep locals employed. Far from being afraid of stopping construction, one of her letters mentions that she halted construction due to excessive heat out of concern for the workmen.
It’s interesting how BS can just take the place of reality if it’s repeated often enough.

Yes this. Also, when you visit it it’s not that weird. Yes some of the angles and doors and one staircase are nonsensical, but a lot of the features were practical to accommodate her physical disabilities. I was surprised how many of the rooms were juts light, airy, and pleasant. The tourist PR spin ends up being irritating when you visit the house.

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Sharks have been around longer than the rings of Saturn.

That’s right! Current estimates suggest that Saturn’s rings are about 400 million years old, while sharks evolved roughly 450 million years ago. Interestingly, that also makes sharks older than trees and grass.

Modern humans been around for about 200,000 years. Humans about 6 million. We were in a stone age for about 2.6 million years.

We were not the first to use stone tools. There was another species, probably a close cousin, that used them about 700,000 years before the first human.

Chimpanzees and some other animals are currently in a stone age.

Dinosaurs died out 65 million years ago. Triceratops were probably the last species to die out.

Grass didn't evolve until 66 million years ago (iirc) so only the last of the dinosaurs saw grass.

Tyrannosaurus and triceratops lived closer to us (65 million years) than the stegosaurus (80 million years).

I have more. I'm full of useless facts.

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) There are at least three people who were born before the Wright Brothers took their first flight at Kittyhawk who were still alive when the Mars Rover died.

When they were born, humankind was stuck on the ground. In their lifetime, they saw single person flight, then military flight, intercontinental flight, a (gasp) female pilot, commercial flights, supersonic flight, space flight, humans on the moon, a probe sent out of the solar system, a robot cruising around on an entirely different planet picking up rocks, and finally that robot had been there so long it died. All in their lifetime.

That's just crazy to me.

Believe it or not but this fact gets even more interesting. The yellow spotted salamander uses photosynthesis in the embryonic stage. It does this by forming a symbiotic relationship with algae, which produces oxygen to feed the embryo as it develops and receives the embryo’s waste products and carbon dioxide. Researchers have even found algae inside the embryo’s cells!

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Greater one-horned rhino or Great Indian rhinoceros population stands at around 3,700 individuals, a significant increase from around 200 remaining at the turn of the 20th century. Strict protection and management action from Indian and Nepalese authorities and their partners are responsible for bringing the species back from the brink.

The Great Indian rhinoceros is definitely a conservation success story in the making, but there are still other species of rhinoceros that are at great risk of going extinct. Only about 60 Javan and about 200 Sumatran rhinoceros are thought to exist in the wild.

There's no need to pump de-oxygenated blood to the lungs when in the womb, because the lungs aren't breathing air yet, and so are not supplying oxygen. All the oxygen comes from the umbilical cord.

So the two chambers responsible for sending blood to/from the lungs are (largely) bypassed.

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Rabies kills around 60,000 people globally every year. To date, only 14 people worldwide have been known to recover after developing symptoms.

Rabies is as deadly as it is because it targets our central nervous system and destroys our body’s ability to perform essential functions. However, it does have a moderately long incubation period. If a bite victim is treated with the vaccine within 10 days of being bitten, they can expect to survive, but by the time symptoms appear, it’s already too late.

This is why every animal- inside or out- should be vaccinated for rabies. Folks often say," My pet is indoors only", but if the pet escapes or a bat gets in the house, the risk is there. And they can transmit it to us. It is a myth that all animals with rabies act like Cujo. Many people don't realize that the only way to test for rabies in an animal is to examine brain tissue. So if a vet has to euthanize an animal that is a rabies suspect, we have to cut off the head and send it to the lab. It is exactly as gory and traumatic as you imagine.

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Many species of shark have seven senses, most notably the ‘man eaters’ (I despise that term) Tiger, Bull, and Great White.

In addition to the traditional five, sharks also possess ampullae of lorenzini (gel-filled pores on their snout - think of the black freckles on a Great White) that detect electrical impulses such as spasmodic movement in water and ambient electrical fields, and the lateral line (a thin organ running down their sides) that acts as a magnetic detector, which allows the shark to orient itself in real time to the earth’s magnetic field, giving it a sense of direction akin to that of a bird.

Great Whites additionally are coated in denticles. Despite their smooth appearance, their skin is actually extremely rough and toothlike. Think of sandpaper on some serious steroids. A Great White bumping into you can actually peel layers off you like a potato peeler. That’s if they don’t give you a bite of course!

On to that, despite their fearsome reputation, Great Whites don’t care for humans as a food source. They need immense amounts of blubbery fat and meat like whales and seals can provide, we’re simply too lean for them to get much nutrition. Most attacks are down to either territory being defended, or simple mistaken identity. They’ve got terrible eyesight, so a human on a boogie board looks exactly like a seal from below. And, as they have no hands, biting is the only way they can be sure of something. It just sucks for us that that’s typically fatal.

Finally, if you ever get a moment, look up spy hopping. Sharks can and will pop their heads above water to get a lay of the land. It’s frightening to behold.

I've occasionally wondered why wetsuits tend to be black. If anything is going to make a human diver look more like a seal to a shark, it's that. Make them out of a primary colour; anything but black. You're basically cosplaying as a seal when you put a black wetsuit on and enter the water.

yes, because the reaction is silicate plus alumnium hydroxide catalysed by water to give aluminium silicate. Something like that. Point is the water is just a catalyst. It's not mud - a watery suspension of silicate particles. Mudbricks are made runny by water, and then dry out (loses the water) to the sun via evaporation, leaving the silicates in close proximity/bonded. Whereas concrete is an actual chemical reaction.

A couple interesting science facts that lead to in interesting likely somewhat obscure fact about an old kitchen appliance. (Although I did learn this from a YouTube video which currently has 1.6M views, so at least that many other people probably know it)

When you cook something in boiling water, is always cooks at the boiling temperature of water no matter how long it's in there. Once water begins to boil any additional heat you apply goes to converting the water to steam. You can't actually get it any hotter. The hotter you make the fire the faster it boils off, but the liquid water never gets above 212F at sea level.

If you heat a magnetic metal up it will eventually lose its magnetism. If it's an actual magnet, you just permanently un-magnet-ed it. If it's a normal piece of metal though it will just lose the ability to stick to a magnet and that property will return when it cools down. The exact temperature this happens at varies depending on the metal.

Combine these facts together and you can make a nearly perfect automatic rice cooker. Basically you take metal pot and put the appropriate ratio of rice and water in it and set it in the cooker. The cooker has a heating element of a known wattage that heats up and boils the water. The pot will sit right at the boiling temperature of water as long as liquid water remains because the water will be absorbing all the excess energy to turn to steam. As long as you followed directions the amount of time that water will take to boil off is very predictable with the fixed heating element. That will be the appropriate time to cook the matching amount of rice. Once the water has boiled off the pot will quickly begin to heat up. Unchecked this would quickly burn and ruin the rice. However, under the metal pot of the cooker is a button that is being pulled down by a spring but is held against the pot by magnetism from an attached permanent magnet. The button is made from a metal that loses its magnetism just above the boiling point of water. Once all the water boils off the pot starts to heat up and quickly demags the button which gets pulled by the spring and automatically turns off the heat. Perfectly cooked rice through physics.

EDIT: [The video I mentioned](https://youtu.be/RSTNhvDGbYI)

If you are heating a pot from below, then the surface of the pot will be higher than the boiling point of water and so will any food that is contact with it. This is why cooks use a Bain-Marie to control the temperature. A bowl sits over a pan of water. The water can only reach 100C (as described above) and so the bottom of the bowl can only reach 100C and no more.

Someone Asks People To Share Facts That “Barely Anyone Knows”, And They Deliver (30 Answers) Sara Josepha Hale is the reason for the myth and celebration of Thanksgiving in the United States. She asked President Lincoln in 1863 to champion a holiday that would bring families together in the wake of the U.S. Civil War. The goal was to get people back in each others company to celebrate the nation. She then helped perpetuate a myth of "The First Thanksgiving" to remind the country of how the colonists persevered with the help of indigenous peoples. Seven years later, other Federal Holidays would officially be recognized throughout the country.
