So, I got an idea where I have this big object (A sphere, in my case) which I want to protect forever/as long as I can. I have spherical, two sided portals that last forever. These portals are like the ones in fireboy/watergirl, and each side can connect to a different portal. I can't have ANYTHING hitting my highly fragile object, so I'm putting this whole thing in space. The people trying to get to my object can break through any physical material, so the option of just covering up my object and sealing it in a hundred layers of graphene isn't an option. If only it were that simple. Assuming I have infinite spherical portals and these spherical portals are unbreakable and unmovable, what arrangement will protect my object for longest? Remember, the portals are SPHERICAL.
No pressure to get perfect logic, I'm not actually using this on a book. Just in my mind, for my own entertainment. I like logic A LOT.
EDIT: The inside of one portal connects to the outside of another.
