The OP only replaces one fiction with a slightly more accurate fiction.  The OP described only of the &#x27;spheres in a vacuum&#x27; version of physics that tends to fall apart outside the classroom.<p>(1) There are no spheres in realworld gravity.  Earth is not round.  The moon is not round.  Even black holes are not round.  Realworld orbits, orbits around non-round bodies, are not this predictable.<p>(2) For purposes of space travel there is no &quot;out of atmosphere&quot;.  There are detectable wisps of gas out almost to the moon.  This is the primary reason orbits decay, especially anything close to earth.  The ISS would fall out of the sky very quickly without constant correction for the atmosphere it is flying through 24&#x2F;7.<p>Pointing out errors in science fiction is a fools errand.  If they listen to you and correct all the errors that you&#x27;ve pointed out, someone else then shows up demanding that all their errors also be accommodated.  The next thing you know Freeman Dyson is on set pointing out that the stars in your backdrop are upside down.  An inaccurate piece of science fiction isn&#x27;t as bad a one that claims scientific accuracy when it clearly stopped listening to the Mr Dysons half way through production.
