in the whole universe there is no an identical proof or example which shows a behavior like "a straight line" and "parallel lines"

it is just a theory which never exists in reality. even one talks about a light's path, the path of light is also affected by the maganetic force. no single thing is scapeable outside the boundry.

Hence, In this whole universe the concept of a straight line and paraell lines obselete. we can't proof it mathematically and physically. if one says we can remove gravitational force or maganetic forces in the way of light, but this wont meet the actual "fact". a fact is fact which testified everywhere with same behavior and results

If the BB is correct, at the moment of the explosion, the laws of physics began their 'appointed/determined/by chance tasks.
In so far as I understand it then, the laws pf physics were present before time began, eh?
