The idea that objects, e.g., rocks, are arriving from the Alpha Centauri system in our solar system appears reasonable and to be expected. However, the study is only a first order crude approximation of the actual interactions. While the study noted the Alpha Centauri system will make its closest pass in about 28,000 years, it simulated the environment between our solar system and the Alpha Centauri system as otherwise unchanging for 100 million years, giving objects from Alpha Centauri plenty of time reach us. If we take the 28,000 years timeframe for our close pass to be typical, there would have been nearly 4,000 close passes by other stars in that 100 million years. Thus, it is a good bet than many of the objects anticipated to be from the Alpha Centauri system come from other sources.
