I read this poem in 11th grade. It was really difficult to understand. The teacher had us read it in class. It was approximately two pages of verse. It took almost 30 minutes for us, collectively, to interpret it.
The poem described what would happen if the sun's gravitational pull were no longer strong enough to keep us in orbit. Instead, Earth was slowly drifting off, on a trajectory that would take us away from the sun's warmth, through the solar system and beyond, although everyone would be dead by then. The poem described how each day was colder. Everyone knew that there was no hope for Earth and humanity.
It may have been written by Ogden Nash or Carl Sandberg. I'm guessing, but it was probably written in the 1960's. Does anyone know the name of the poem?
