Dinosaurs are not extinct
Kindergartners will laugh at you if they find out you still believe dinosaurs died out 65 million years ago. They’ll point out the blue jays, pigeons, hummingbirds, and seagulls flying around your neighbourhood with their dinosaur genes. As paleontologist Steve Brusatte, author of the book The Rise and Fall of the Dinosaurs, told Reader’s Digest, “Today’s birds evolved from dinosaurs, which makes them every bit as much of a dinosaur as T. rex or Triceratops.”
Women suspected of being witches were not burned at the stake
First, no one was burned during the Massachusetts Bay Colony witch scare in 1692. In Europe, convicted witches were sometimes burned, but in England, they were hanged, and that’s the tradition the colonists followed after a group of young girls started having “fits” that the doctor blamed on supernatural afflictions. In all, almost 200 people were accused of being witches; 19 were convicted and hanged. One person was crushed to death under stones. Another myth about the Salem witch trials is that all the accused were women. Five of those executed (including the elderly farmer who was pressed to death) were men; plus, the accusations affected people from all circumstances and social positions.
There are more than three states of matter
You may have learned about three—liquid, solid, and gas. Those are the most common states of matter that we find here on Earth, but beyond our atmosphere, there’s a fourth state—plasma—and it might be the most common in the universe. When you add enough energy to an atom, its electrons can get away from its nucleus and react with a different nearby nucleus, creating plasma, which consists of highly charged particles with very high kinetic energy. Gases like neon are goaded into a plasma state by electricity to make glowing signs; stars are basically huge balls of plasma. But that’s not the only extra state of matter: In 1995, scientists created one called the Bose-Einstein condensate, where matter is super-cooled to almost absolute zero, causing molecular motion to practically stop. Nobody knows whether Bose-Einstein condensates exist in nature, but they can be made in a lab. Researchers are also investigating other states of matter, so the number could keep growing, according to Gizmodo.
