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
Can Jupiter be ignited? - Physics Stack Exchange Our solar system itself contains two candidate "Earths" One is Jupiter's moon Europa and another is Saturn's moon Titan Both of them have the problem of having at low temperature as Sun's heat ca
Black and white matters. But why and how? - Physics Stack Exchange So a metal door in the sun will transfer the heat of the visible spectrum to the interior if painted black, will reflect it back and keep the interior cooler if painted white It is a good reason for painting roofs and walls white in hot countries A white car is also better in hot countries for this reason
How hot can metal get in sunlight? - Physics Stack Exchange I will make some 5mm blackened steel letters for a building Now, in the sunlight in summer, how hot can they get? EDIT: i want to place some LEDs on the back of the letters now the question is

Calculating the amount of heat energy radiated by sun How do I calaculate the amount of heat energy radiated from the sun in one minute?? Well, i tried some stefan method, but the answer seems far off from the correct one well, i would thus strongly want to have some help in this regard
special relativity - Is it theoretically possible for a proton to . . . Is it possible to destroy the solar system by launching a proton at the sun at a speed approaching c (as seen in cern 0 999999991) and then using the gravitational pull of the sun to accelerate it to an even faster speed such that its mass increases to a ridiculous amount and the resulting collision either creates a black hole or otherwise
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?
How does the Suns gravity affect our weight? At a higher fidelity, one might even acknowledge that gsun g s u n depends on the current time of year During summer and winter, gsun g s u n are different because the Earth is at a different distance from the sun
