Dowker is focused on the relationship between Quantum Mechanics and Gravity, which is linked to time via Einsteins Theory of General Relativity, and thinks this new perspective on time, may be useful in bridging the two main physical theories of reality, which to date, have been irreconcilable with each other.

The The Standard Model answers most of our questions about reality, but it doesn't explain Gravity.

However, not everything has been handled in such a manner, as Gravity is not understandable in terms of other phenomena.

While we do want to ignore some aspects of the system, we must take care not to neglect too much, or the wrong thing: should we ignore the effects of Gravity too much, the model then leads us to believe the ball will travel entirely vertically. Useful models make things "as simple as possible, but no simpler".
