ok I know that anybody in the heavens will bend spacetime with the gravity it has. What I was wondering was how do we measure around them like from the Earth to mars. When Mars in now quit on the opposite side of the sun ( so we can see it at sunset). do we measure the parabolic curve in spacetime that light takes from the sun's gravity or do we take into account the curve and make adjustments to get a straight line through the system for distances between the two planets. Also to go even feather do we take into account the curve around the planets as well?
