Predictions/ Results
The elastic universe theory makes multiple qualitative predictions:
 Existence of 3 lepton generations and relationship between these generations.
 Interpretation of the Minkowski metric.
Further predictions are available in the approach:
 Interpretation of QED.
 Interpretation of GR.
 Existence of a relationship between GR und QED.
The calculated numerical results can be directly experimentally verified:



All calculated quantities are more precise than the experimentally measured ones and lie within the 3σerrorinterval of the experiments. 
Falsifiability
Dispersion
Each lattice with a finite lattice length [math]\displaystyle{ a }[/math] creates – as opposed to vacuum – a non linear relationship between angular frequency [math]\displaystyle{ \omega }[/math] and wavenumber [math]\displaystyle{ k }[/math] of waves (dispersion relation). So far, however, the universe shows a linear dispersion for electromagnetic waves [math]\displaystyle{ \omega(k) = c \cdot k }[/math], where [math]\displaystyle{ c }[/math] is the measured speed of light. This means that all frequencies of electromagnetic waves move with the same velocity [math]\displaystyle{ c }[/math] in vacuum, yet in a lattice higher frequencies are slower.
This means that the lattice theory only makes sense if the lattice is so small that its influence on the dispersion relation is below today's measurement capabilities.
This problem exists for all theories which initially assume a quantised spacetime, so also for Loop Quantum Gravity (LQG). In this case, the problem was already studied ^{[4]}. As an upper limit for the size of lattice structures, this research suggests that the lattice length must be of the same order of magnitude as the Planck length, so [math]\displaystyle{ a \leq l_P =\sqrt{\frac{\hbar\,G}{c^3}}\approx 1.616\cdot10^{35}m }[/math].
Schematically: In red is the dispersion through a linear chain as a model for lattice structures. In the case of wavelengths close to the lattice length [math]\displaystyle{ a }[/math], the dispersion changes considerably from the meascured vacuum dispersion (blue). If one gives the model a lattice length close to the Planck length, then today's known wavelengths (green), left on the illustration, move far beyond the lattice length. This is a situation where the two descriptions are almost undistinguishable.
Granulation
A further argument, which limits the possibilities of lattice structures, has to do with granulation. Object which are at great distances would appear blurred or "grainy" because of the lattice.
No study is known which considers this argument, but it could give an upper bound to the length of the lattice structure.
Causality
The postulated interpretation of the Minkowski metric and the hypothetically possible existence of a universal observer raises the question to whether causality is ensured. To this end, see the discussion.
