Ok wait. Thats hillarious i wish i knew this earlier. So the earth emits light and heat, yet we dont feel this heat from the earth, or see the light (at night time when there is no sun above us).
The earth is huge compared to the sun (in FET) and the heat and light would leave the earth evenly into all areas of space, the tiny sun would only reflect a small portion of this, there is no way this would be enough for it to emit/reflect the kind of heat that it does on a hot summers day. When you go in the shade (under a tree) you dont feel the same intensity of heat coming from the ground, its cold. You can FEEL the suns heat, if the heat was reflected (how do you reflect heat anyway) from the sun, you should also feel it coming from the earth, because the earth would have to be really hot, as only part of the earths emited heat will be reflected back.
