Red Giant


        When the Earth comes to an end, it will do so as a consequence of our sun consuming its hydrogen.  The hydrogen, as I understand it, becomes helium and when the hydrogen is gone, the sun will brighten and expand to that point where it may or may not engulf our planet.
 
      When I was a day younger I thought this understanding of the Solar System being swallowed by the death of its star most depressing.  But this morning I spent over half an hour watching the daytime television in the dentist's waiting room.
