unstable Planet Orbit

Robert sent in this one, https://phys.org/news/2023-02-solar-gained-super-earth.html … which is basically, what would happen in the solar system if it gained a super earth, a modeling exercise, in one respect, from a gravity only view of the universe. The full article is available at https://arxiv.org/abs/2302.0641 … or https://doi.org/10.48550/arxiv.2302.06641 … Robert adds a comment, saying that even the gravity only based simulation covered just 10 million years, a blink of an eye on the consensus solar system timeline. As Velikovsky pointed out, he adds, electrical interactions would rapidly settle down a disturbed planetary system. An interesting piece of research after the scientists, in question, wondered what might happen if our solar system captured one of those super earth planets out there in space. Super earths are common around other stars, and some 1500 have been discovered so far. Our solar system doesn’t have one but what if it captured one. The article describes his simulation and research and he goes on to say the results reveal the dynamical fragility of our existing planetary configuration. A remarkable shift of opinion. Recommended.
