SUMMARY
In our spacetime, we can distinguish between different inertial frames due to variations in the cosmic microwave background (CMB) radiation. This phenomenon indicates that the metric for our spacetime on large scales can be described mathematically, as outlined in the provided references. Specifically, the determinant of the metric tensor, det(g), is relevant in this context. The discussion also highlights that the relative speed and position of celestial bodies, such as Jupiter, further exemplify this distinction between inertial frames.
