Four-Dimensional Kinetic Cosmology (4DKC.net) unifies gravity, electromagnetism, and quantum mechanics in a single kinematic framework.

The Einstein equivalence principle tells us you cannot locally distinguish a gravitational field from constant acceleration. The surface of the Earth accelerates upward beneath your feet exactly as the floor of a rocket in deep space. This raises a simple but profound question: if everything is accelerating outward, where is it accelerating to?

The answer has been in plain sight all along: our three-dimensional space is moving uniformly through a large fourth spatial dimension L at speed c. Electromagnetic binding extracts kinetic energy from this motion to create matter and launches persistent deceleration wakes - history-dependent disturbances that flow inward toward bound structures. These wakes are what we experience as gravity.

4DKC requires no Big Bang, no space-time curvature, no dark matter or dark energy, and no singularities. Black holes become finite kinematic regions where the manifold flow simply slows to zero. The same wake mechanism naturally produces flat rotation curves, the radial acceleration relation, cluster-merger offsets, and the arrow of time - all from ordinary electromagnetic binding in a single 4D spatial manifold.

The model makes clear, falsifiable predictions, including subtle directional variations in the one-way speed of light along deceleration gradients.
