light rays are reflected off the object
A fire and a flashlight are able to add light to the dark to help people see objects.
They are special.
It isn't possible
Yes objects less than a mm apart can be seen as distinct objects. The lowest limit for the human eye to see is 0.1mm. If objects are any closer they are seen as being one item.
No, They would always see you as Offline on their pals list

Heat
An object that does not give off light on itself is still able to reflect incoming light. This is the case with most objects arount you that you see, precisely, because they receive light from the Sun or from some lamp.
diffuse reflection
diffuse reflection
Well you can see the moon during the day time maybe its because the objects (planets or stars) are ages away. Also since its bright in the day time that also could affect being able to see or not to see the objects.
No, everything that we can see (besides objects the produce light eg sun, light bulb) reflect light. If it didn't reflect light we would not be able to see it.
