1. What does "a displacement of time" mean in this context?
2. Does this "coincidence" imply a coincidence between the two world wars?

Context:

No one in the West was unaffected by the two world wars and the interesting **coincidence** may be that the advances in contemporary science that show a breaking of symmetries, **a displacement of time** and an upheaval of old laws and orders all happened against a backdrop of split and rupture on the world’s battlefields and a radical breakdown in any consistent moral and spiritual tradition.
