This paper was by a cosmologist with heaps of papers in other areas and just a single paper in this area, highly publicised in the climate change news.

All the reports around this were hyperbolic. I'd be waiting for a bit more research in this area. It reminds of other recent paper that said possible close passes by other stars had a huge impact on the environment according to simulations. No mention of the problem predicting orbits over tens of thousands of years.
