Why not get the best of both worlds and just do some short trips in the meantime? I noted that I always start missing the action in the bubble after roughly a week. So what I do now is use neutron boosts to get into uncharted regions fast, then quench my exploration desire, and when I am satisfied, I go back the same way.
That is not to say I will never go on a long expedition ever, just not for now, as I am still not done with all the cool stuff you can do in the bubble. Eventually I will certainly also set off on one!
That's a nice advice. I always forget about the Neutron Jumps or the Jumponium... this is because I lived for years on my own and I'm still not accustomed to all the technology discovered while I was out far far away
