It is wonderful to have you aboard, @tiedinbluetights. When you have finished reading this, I hop that you will continue with the Bandit Scout on Newhome. You can find it by clicking on my banner.tiedinbluetights wrote: ↑6 months ago ...
I do have a question, that may have been already answered by some of the commentators, so I may stumble upon it eventually, but just in case it was not asked, I can't help but wonder if you did the GR calculations yourselves for the trip to Newhome or if you used an online calculator like omni?
To answer your question. I did the calculations using Python. But it is all Special Relativity and not General Relativity. Traveling mostly through essentially empty space, that is probably a reasonable approximation.
