Water IS actually blueish-greenish in color. It's just a very very weak tint, so it usually appears simply transparent (and reflecting the color of stuff around and inside it). But when it's in very large volume, in a perfectly white room, under perfectly white light, the water's very own teal color becomes visible. Similarly, the sun seems goldish-orange from Earth due to the atmosphere. The light of the Sun itself is mostly white. However, if we were to analyze the light very accurately, it's actually a very subtle pale greenish/lime. We still see it as plain white in space, but I just think it's so cool.

"The power required to make a 1000 decibel noise for one second is equivalent to the power of the entire sun for 4 billion years" A family member was talking about a "600 DB" car horn he bought over the holidays, and I was trying to explain to him that 600 DB is enough energy to destroy the planet and then some. Lol

Infrared light was discovered all the way back in 1800. By accident. With a thermometer. William Herschel (who also discovered Uranus) was experimenting with a prism. He wanted to see if different colors of light had different temperatures. So he had the room completely dark except a beam of light hitting a prism and casting a rainbow onto the table. He had placed thermometers in each color band to see if there was a difference. As a control, he had an additional thermometer past the ene of the light below the red band. Except when he compared his readings he got something strange: the control thermometer was reading the highest temperature of all. This didn't make any sense. Was his thermometer faulty? He tried a few more tests with more thermometers in other places and came to an inescapable conclusion: there must be an additional invisible "color" below red that carried more heat than any of the visible colors. He named it infrared, which just literally means "below red".

In Newtonian physics it was generally accepted that a planet call Vulcan was closer to the sun than Mercury. The math needed some kind of extra planet to explain Mercury's weird orbit. Astronomers around the world for a couple hundred years would confirm a sighting, but it would never be there when you tried to use physics to predict where it would be. Even the famous french scientist that found Neptune with math predicted Vulcan using the same formulas. The idea didn't die until Albert Einstein changes physics with special relativity. Suddenly all the orbits of our planets make sense and Mercury has a weird orbit because it is so close to the sun. Basically, smart dudes figured a planet existed when it didn't because their system didn't work out. It took changing the system to meet reality. Confirmation bias is a scary thing.
