How to set up a No Mans Sky type of infinite flight ?

So i cant move a cube through the x,y or z axis beyond 100000 units without a lot of spartial jitter happening.
Totally understandable.

But then how do i go about setting up infinite flight so that if i procedurally generate a couple trillion spheres as planets ;I will be able to fly to any one of them ?
(and then I have a similar question regarding the positions of procedural objects because they will surely go beyond 100000 units)

Is this something that we can do in unity ?
any help and hints would be greatly appreciated.

The traditional solution is to use a “floating origin”, as described in this paper.
