 Context examples 

The research exploits a new theoretical model based on the scale invariance of the empty space, potentially solving two of astronomy's greatest mysteries.

(There May Be No Dark Matter, Dark Energy in Universe, The Titi Tudorancea Bulletin)

In this model, there is a starting hypothesis that has not been taken into account: the scale invariance of the empty space; the empty space and its properties do not change following a dilatation or contraction.

(There May Be No Dark Matter, Dark Energy in Universe, The Titi Tudorancea Bulletin)

Based on this hypothesis, Andre Maeder, professor in UNIGE's Faculty of Science is now re-examining the model of the universe, pointing out that the scale invariance of the empty space is also present in the fundamental theory of electromagnetism.
