In Portal, using the portal gun to get to the moon is the obvious space travel usage, but I think people are overlooking how it’d let you trivially break the rocket equation.

Hell, you could build a >1g torchship using nothing but the ocean.

      @susul@misskey.heonian.org 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
