Hemisphere is still expanding

Three billion years
we have survived
and
another few more
we have not yet met
how at the end we shall
can you assure?

they know no less
no more
we all expand to maximum
and
then relax
that's for sure

so will the world
may also collapse

neither you nor I will know
so enjoy the night

once more
with the ones you loved to,
as before
no less
any more

we all expand for sure
to that extent only
no less no more

will we meet then
can you assure

four billions is a long time
we may not be any more
but we will today
enjoy as before

once more time
tonight
of that be sure
