Since it seems like no-one feels like voting and/or talking about the vote, I will ask some questions for the future.

Have you figured out what it would take to terraform planets yet, energy and resource wise?
Our space-craft's sensors, do we got anything more exotic than just light? And if we WE do, do the aliens?

How does a portal work when connecting two areas with time flowing at different rates (like into a Time-stopped zone)? Both magic portals, and our SCIENCE! portals when we get them, if there's any difference
