First off, Frank wants everyone to be aware that an asteroid (2010 TK7) has been found to be stable in the L4 point in the Sol/Earth two-body system. (Of course, anyone paying attention to the science news would already know that.)
Now that we've gotten that out of the way, back to the normal stuff. So, Frank is really stuck on trying to locate the other end of the Door. Now he's even gone so far as to give Tom an old-style film camera and tripod, which Tom is supposed to set up, point 'north' (see discussions of 'east' and 'west' in previous postings), and take a few time-exposures of the stars. Frank will then use that information to plot out the relative position of the stars as well as establish the speed of the planet's rotation. From all that, Frank is very hopeful that he'll be able to identify the other end.
A recent concern that came up in random talk in the lunch room is that the other end of this obviously-alien device may connect with the home world of its creators. The worry here is that we might not be opening up a tunnel through space so we can go out and explore, rather we're opening up a hole that will let others come 'visit' us.
What do you think?
