- 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
- everyday life - Why do sunbeams diverge even though the sun is much . . .
The Sun is very far away and the beams are pretty much parallel, but they're pointing towards you, and perspective makes them appear to converge towards the vanishing point - which in this case is the Sun's location in the sky
- photons - Light formed by the sun? - Physics Stack Exchange
The photons take thousands of years to "fight" their way to the surface of the Sun, but then escape into space as visible or near visible photons at the speed of light I am really confused about how the sun produces light I understand that through nuclear fusion, energy is formed, but isn't this energy in the form of thermal and gamma photons?
- Nuclear fission in the Sun - Physics Stack Exchange
The Sun's energy comes primarily from fusion of light elements in its core It is estimated that a very small fraction of mass of the Sun (~$10^{-12}$ times the abundance of hydrogen) is uranium (b
- 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?
- What if the Sun became a black hole? - Physics Stack Exchange
If the Sun became a black hole, but the mass remained the same as it is now, the Earth would orbit in the same manner that it currently does because of the reason that the mass does not change (gravitational field stays constant) However, does the curvature of spacetime change in the region where the Sun used to be located?
- Why do we say that the Earth moves around the Sun?
3 The sun, moon, earth (and so on) all move around each other The reason we say the earth moves around the sun is because the effects are more visible on a macro scale, and easier to predict with reasonable precision
