Particles move through space-time in such a way that the sum of their experienced velocity through space and time is equal to the speed of light, given appropriate units. This behaviour is the same for all observers of the particle, regardless of their motion with respect to the particle.
Mainstream Science accounts for this behaviour via the theory of General Relativity. This is an ingenious and very accurate theory, but does have some shortcomings. It has no notion of what space is, and therefore cannot account for the initial state of the Big Bang. That is a complex gap. It is incompatible with Quantum Mechanics, which is a simple paradox. It accordingly has an absolute Occam Score of 5000, and a relative Occam score of 1000 relative to the Big Bang.
The QO explanation stems from the QO concept of interconnectedness. It has an Occam score of 0100 relative to QO, and 3000 absolutely. It is therefore to be preferred.
