I really hoped to be a part of one the expeditions to this world. Having developed a background in archeology in my spare time I was interested in finding out what happened on this planet. Why it was so similar to our own, why did we find it, and most importantly where did everyone go?
Unfortunately for me I had two things going against me. I was getting a little old by their standards, and I was a propulsion expert. Let me explain, on missions like this... you know to other universes they are concerned that the very few people that get to go are in perfect health. The loss of communication once they are on the other side complicates this greatly. Anything they can do to decrease the number of variables that might impact the mission is very advantageous. It's not like you could just dial 911 emergency and have an ambulance come if you had heart problems or you tripped and broke your leg. No you would be on your own with your crew and that's it.
Second being a propulsion expert was another handicap (strange huh?). Basically I was considered "too valuable" to risk losing on one of these missions.
