@[email protected] I was thinking that the portal would be very short-lived, because the surface you placed it on would be quickly destroyed, but there'd be a short period where the initial gamma rays make it through.
but yeah, if you can somehow keep it open longer than milliseconds after the instant of the star's collapse, you'd absolutely wreck anything near the endpoint
