Does the project invalidate existing physics?
No. But it gives a coherent foundation for what previously appeared to be disparate ideas and results. In doing this, it introduces new concepts that are different from those in existing physics. For example, it suggests that space is fundamentally discrete, rather than continuous. It also suggests that time is fundamentally different from space rather than being just part of a combined spacetime. Despite such differences—which are primarily relevant on extremely small scales—existing physics emerges. In addition, our model appears to dovetail very elegantly with many recent formal directions in physics. (See Relations to Other Approaches.)
