- A rainbow has no independent reality. Sunlight and raindrops are not enough to create one. An observer is necessary for its existence, by standing exactly where the 42-degree refraction geometry gets completed. One bit of evidence that they’re not real is that rainbows not only cannot cast shadows, but also do not cast reflections!
- Usually, always noticed that reflection in a mirror is reversed left-to-right. But why isn’t it also reversed top-to-bottom? This has engendered heated logical arguments. Think about it.
- Nearly the entire Sun, all two octillion tons of it, creates neither heat nor light. Instead the bright ball you can sometimes see through thin clouds is just the thin surface where its energy escapes. Its actual power of 4 trillion watts, equal to 96 billion H bombs per second, is generated in a tiny blindingly dazzling ball at its core, with just ½00th of the Sun’s volume
- What kind of energy do you think it emits most strongly? Heat? Ultraviolet light? Gamma rays? No. Its peak emission is ordinary green light. That’s why that color is the one our eyes most easily perceive
- If you dug a hole clear through the Earth, sucked out the deadly hot air and then jumped in, how long would it take to fall from California to New Zealand? Answer: 90 minutes. The same exact period early satellites took to orbit around Earth.
