I mean in the vacuum of universe, what actually determines the pole of a star, and shouldn’t the gravity of a star should work in all directions. So why we don’t have planets with orbits intersecting perpendicularly with each other. Is the fabric of space-time literally flat, or plane?
It’s even worse than you think…
The universe is a single point! The Big Bang is the existence of matter and the continuous expansion of time and space within a singularity — an infinitesimally small dimensionless point. Every point in the universe observes itself to be the oldest and most centralized point in the entire universe – because we are a point!
The reason that planets tend to orbit in a plane around the equator of their central star is because of the accretion disc model of Solar System formation:

I’m sure we will find some really oddball Solar Systems out there that have really bizarre orbital characteristics because they may be formed from merging Solar Systems or whatever; but the accretion disc model seems to be the norm.
