A black hole is the answer I think.
Answer:
The electronic configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6 and Fe3+ is 1s2 2s2 2p6 3s2 3p6 3d5. Fe2+ contains 2 fewer electrons compared to the electronic configuration of Fe.
That's 'centripetal acceleration'. It points toward the center of the circle in which the object is traveling, even if it's only a temporary piece of a circle.
That is called constructive interference. If they meet and cancel, it is destructive interference
