Why does the surface of the moon seem much darker compared to the surface of the Earth?
The moon actually has a very low [albedo](_URL_0_), it only reflects about 12% of light that shines on it. Snow and clouds reflect up to 80% while even soil reflects 20-30% When we look at the moon it
Why don’t invisible rays like wifi and satellite hurt humans or animals?

Why are female pornstars paid more than male pornstars? Isn’t that illegal?
How many beautiful women do you know that are willing to let a complete stranger fuck them in the ass and spray semen on their faces? Now, while you're pondering that I ask you, how many guys do you k
Why can’t Solar Panels be at a 0° (Parallel to the ground) Instead of at an Angle?
The sun is never directly overhead north or south of the tropics, so it'll be less efficient. Panels in North America and Europe should tilt south to get the best exposure angle. There's also the issu
