Is the universe deterministic? How can we explain this?
Yes it is deterministic from the higher geometric vantage point.
From the lower physical vantage point, the universe is stochastic.
This comes from the fact that the universe is two dimensional or flat. One can either view the universe from above or from below.
From the higher vantage point, the universe exhibit geometric properties. Geometric properties are immutable, permanent, unchanging.
On the other hand, physical properties, which is the view from a lower vantage point, are contingent, and ephemeral. Matter responds to heat and other physical factors. For example matter changes its state from solid, liquid or gas, according to temperature but this cannot be applied to geometry. We cannot apply heat to a triangle.. for instance.
There is a distinct break between the mathematical principial realm of geometrical archetypes (ideal shapes) versus the realm of ephemeral, contingent physical manifestations. The former takes precedence over the latter because principle take precedence over manifestation.
Geometry which form the realm of principles is immutable while physicality exhibits fleeting characteristics. Examples of physical properties of matter include: temperature, viscosity, pressure, solubility, electric charge etc
The connection between the realm of principles and the realm of physicality or matter is magnetism, which is itself invisible. Magnetism is the bridge between the higher and the lower realm. Magnetism is the interface between the realm of archetypes or ideal shapes and the realm of physical manifestation.
