Question

if you were an astronaut in the middle of the near side of the moon during a full moon how would the ground around you look how would earth high in your sky like describe what is in sunlight and what is in darkness

Answer 1

It would look in a distinguishable way where the light is in and the darkness is at. This phenomenon would be described as the separation of where light can pass through and is plastered and where the light is absent darkness is present. Hence darkness is only the absence of light.

Answer 2

In a full moon the earth is between the sun and moon, but not blocking the sun from the moon (that's a lunar eclipse and only happens sometimes).  This means the ground all around you would be illuminated (daytime on the moon). The sun would be illuminating the back of the earth from your perspective and so the earth would appear dark, like a new moon does to us on earth.
