    Just to add more confusion there is a way to travel and come back to your starting point with no time elapsed at all. There is controversy about being able to arrive at a time before you left. It involves 2 black holes, they must be colliding, and they must be spinning. there is a path through the vorticies that does allow one to end up back where they started at the time they started. It has to do with the frame dragging a spinning black hole produces.

    I'm not saying it isn't so, but I'd like to read the fine print on that one. I'd like to see someone try it in a real-life spacecraft and live to tell the tale.

    Well.... this is about a particle, of course we are an assemblage of particles. Now as to if that assemblage comes back assembled in the same way it left.... well that is a different matter! To be honest we never got into the math of the collision of spinning black holes. My prof admitted it was way over his pay grade but we just spent a couple a classes discussing the event. Of course the Kerr metric had only recently (relatively) been solved and everyone was still excited about it.

    I worked for RCA corporation in Findlay,Ohio for 31 yrs starting in 1972. We made integrated circuits including radiation hardened circuits designed to endure the rigors of space travel. We made a lot of IC's for the government and NASA and some of our IC's went into the Voyager missions. I remember the company passed around a sheet of paper for all the employees to sign and this was later miniaturized and etched into a metal plate which was attached to one of the Voyager craft (I don't remember which one) So out there somewhere, a little part of me is dancing among the stars. Pretty cool huh?

    I remember when it was launched. The moonbats had a fit that we were sending radioactive RTGs to ETs that might be too stupid to know that it's dangerous. Stupid idiots.

    Yeah ETs are in interstellar space and are too stupid to handle some long ago expended RTGs. :lol
