I have a question for the community:
Let's say that we have a planet, very much like the earth (tilted at 23.5 degrees) and its sun (a normal yellow star). The planet is populated by normal human beings or human-like beings who have been living on its surface for countless years (say 2-3 billions).
Now let's suppose (by whatever magic mechanism) that a thin translucent and indestructible veil has suddenly started drawing over the sun. Since it is a big star, it will take time to cover the entire sun but let us suppose that the star is covered entirely in a 360 degrees direction in about 6 weeks' time. (The planet orbiting the star is untouched and unharmed and it continues to rotate and orbit the star.)
Also, let us suppose that this veil lets out as much light as you would see on a cloudy day when the sun is directly overhead at 12 noon. But it also absorbs most of the heat of the sun and transmits to the planet only 25% of the normal heat received by it everyday.
Now what would happen to the planet (that is very much like the earth) and its population?
What will the sky look like?
What will happen to the surface temperature? How long before cold bitter winds blow across all the surface of the planet freezing everything in sight?
How long before mass extinctions start to happen?
