How much lux does the Sun emit? - Physics Stack Exchange I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly Now the
What would happen if Jupiter collided with the Sun? This question is inspired by a similar one asked on Quora Let's say a wizard magicked Jupiter into the Sun, with or without high velocity What happens? The Quora question has two completely oppo
What is the simplest way to prove that Earth orbits the Sun? Assume you're talking to someone ignorant of the basic facts of astronomy How would you prove to them that Earth orbits the Sun? Similarly, how would you prove to them that the Moon orbits Earth?
Why is the solar noon time different every day? 0 A solar noon is defined when the Sun is at the zenith (directly above) Since the Earth revolves round the Sun, the point that is directly above would have changed because Earth is in a different point from the previous noon
How hot can metal get in sunlight? - Physics Stack Exchange I quite liked this one [archived] describing measurements on cars It shows that things left in the sun can get significantly hotter than the surrounding air (although there are some issues with the method used, the conclusions are mostly valid), One final note - how hot things are is not the same as how hot they seem to be

Why does the road look like its wet on hot days? The sun light in the direction of the road gets refracted do to the temperature gradient (continuous change) of the layers of air This refraction causes the redirection of the sun rays and finally it gets reflected (total reflection) from the layers of air near the surface of the road
