## Abstract

**:**

## 1. Space-Time-Matter Theory

We presently have in mind as ultimate goal a pure field theory, in which the field variables produce the field of ‘empty space’ as well as the ... elementary particles that constitute ‘matter.’

## 2. Physical Interpretation

Space, time and mass in themselves are doomed to fade away into mere shadows, and only a kind of union of the three will preserve an independent reality.

## 3. Lorentz Violation in the Flat-Space Limit

## 4. Conclusions and Discussion
