    I'm pretty sure my cats understand that we revolve around the sun, not vice versa.
    The sun isn't revolving around the earth.  Rather the earth AND the sun are both revolving around a common point.  The sun's position is not fixed in the relationship.  That said, the sun is so massive that the point around which they are revoloving is within the sun.  I believe that's true for every planet in the solar system except Jupiter, whose center of mass with the sun is actually outside the sun.

      Jupiter makes more of a case for itself, pulling the sun about a point pretty close to its surface. But I suppose the movie must treat those other planets as smudges on some crystal spheres or something.

      The sun/earth barycenter isn't quite so noticeably different from the sun's own center. In some technical sense, though, the movie misses being completely wrong by six hundred and some parts per million.

      •  Well if you dilute wrongness enough (6+ / 0-)

        and then shake it 10 times up, 10 times sideways, and 10 times forward and back, then dilute the wrongness some more, and repeat that process 30 times, it suddenly becomes a remedy that makes things correct, doesn't it?

      •  No The Movie is Still Zero Percent Correct (1+ / 0-)

        I suspect (and I have no idea because obviously I'm never going to watch it) that they're going to point out that from the perspective of an observer on earth, everything in the Universe is moving away from us at a speed relative to its distance from us, and then they're going to say: "That wouldn't be possible unless we were at the center of the universe."

        Of course, that's a complete lie, because if you were to go to any OTHER point in the universe, you'd see the exact same thing... that everything you could observe was moving away from you at a speed relative to its distance.

        I suspect they also won't mention that--from a cosmology standpoint--the Universe doesn't have a center, otherwise they wouldn't be able to say the earth was it.

      The earth and the sun and all the other planets revolve around the massive black hole at the center of our galaxy. In turn, that black hole is also moving through the universe.
      The funny thing is that the universe has no center (at least not in the classical 3D Euclidean sense).

      This all argument today is silly from a scientific point of view, just because that when it comes to physics, both "Heliocentric" and "Geocentric" models have the same validity - it all depends  on the reference frame of the person taking the measurement.

      In reality, the Geocentric model is more useful in a sense that this is actually what we see - the sun revolves around the earth. However, this will lead to really "ugly" equations when we try to describe the motion of the other planets in our reference frame - and there is nothing Physicists hate more than an ugly equation.

      TECHNICALLY we can solve these equations (And NASA does it on a regular basis) but it is much easier to solve the nicer equations and then transform the results into the reference system where we make the actual observation.
