Are we seeing the same star as Electromagnetic radiation orbits a large mass OUR GALAXY s core?
It’s very unlikely that this is occurring. (Though I must admit it could be theoretically possible) Every star we look at is moving in an almost linear manner away from the centre of the universe. In other words the universe is expanding outward from the centre. However as we are not at the centre of the universe some stars are moving towards us. If we were seeing the light from the same star in an orbital pattern the star would appear to be stationary in its radiance. Remember that we can determine the direction of motion by the frequency of the light emitted from a star. This motion proves that they are in fact independent stars with diverse vectors. Secondly as you mentioned we would see a mirror image of the star on the opposite side of the earth. If this was true, this image would appear to have the same vector (in reverse) as the first image. This effect would cause the universe to appear as if it were expanding directly away or towards the earth, making the earth appear to be th
