Theory of Relativity was in spiritual Field before EINSTEIN .

"The  reality  of  everything is the same  INFINITE. This is not Idealism.It is not that World  does not Exists . It has a  relative existence, and  fulfils  all its requirements . But  it has  no independent existence.It exists  because of the Absolute Reality beyond Time, Space  and Causation"
 ---Vivekananda( In 1890-s);  Delivered  at the  home of truth, Los Angeles, Califormia ; Ref ;Complete works of Vivekananda ;  17th  reprint  1992; Mayavati  Ashram ;Vol 2, P,  32-33).

The   whole  of  Cosmic play  a  4- dimentional GAME  (time-Space)  and Light (EMF) and  proving all  our perceptual  truth throughout  our   life  as  total  Relativity ( Duality ) , while the  TRUTH  ABSOLUTE is beyond  human  Comprehension  and with /within the DIVINE (un-knowable).

You may ask :  'Is it POETRY' ?
To me  any   journey to  TRUTH--Absolute,--  is POETRY, -in any form ,
Prose ,  Rhyme  or Music !
