Watched a video about the moon and possible ice in craters on the south pole. If ice on the moon is exposed to the direct sunlight it obviously evaporates away and since there's no atmosphere on the moon it floats out into space. But what happens then? Does the water drift apart into individual molecules of water floating in space by themselves? Or does it somehow break down into its individual atoms of hydrogen and oxygen? Does that mean that in the vastness of space you can occasionally find single particles of stuff just floating? Or does the gravity of earth cause it to slowly fall towards earth? I'm having a hard time wrapping my head around that.
