Why the sun can not light the space like our earth? the space is much closer to the sun than earth! |

Answer» It does, were you to look at the SUN DIRECTLY in space, you'd be blinded. That's the point of those gold visors on space suits. The reason it doesn't appear to is that there's very little for the light to strike. Think of shining a flashlight into the air, it has effectively no visible effect. Now if you shine it at a tree, it gets nice and bright. It's the same AMOUNT of light, but it doesn't appear so because we can't see it travel. Now if you mean why isn't space blue, like the sky, that's because when SUNLIGHT filters through the atmosphere, it's interaction with the various gasses scatter the blue light most, giving us that nice HUE. Space, obviously for the most part lacking an atmosphere, doesn't scatter the light, hence the black. |
