Interstellar -LRB- 2014 movie -RRB- : Cooper got coordinates from the message in Murph 's bedroom . Where did those coordinates come from originally ?
In the movie Interstellar , Cooper sees Murph sitting in her room after he reaches the 5D world . Does it mean that the light reflected off of Murph crosses the spacetime barrier of 3D world & enters Cooper 's 5D world ? If Cooper can see Murph , why ca n't she see him ? Principle of reversibility right ?
