All that they can do (and do do) is simply 'reschedule' it - i.e. borrow loads more to keep honouring the bonds it has to pay up on. But this of course increases the debt. Hence, huge snowball.
As a point of interest, when central banks buy the bonds, money is created - unfortunately more has to paid back.
