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.
