| Sep 25, 2014 at 22:18 | comment | added | Noah Schweber | A quick comment: certainly, in order for $\mathbb{P}$ to preserve $\aleph_1$, the continuum hypothesis must fail in $V$: otherwise, by well-ordering $\mathbb{R}$ in $V$ with ordertype $\omega_1^V$, the set $A\in V[G]$ would yield a countable cofinal sequence in $\omega_1^V$. | |
