2.The enormous amount of ash and ejecta pumped into the atmosphere from the crash would shroud the continent of impact in total darkness for some time.
3.The discovery provides important evidence of the presence of impact ejecta near the craters in the sampling area of Chang'e-5, which was previously determined through the analysis of remote sensing data.
4.And the ejecta or the stuff ejected has momentum just like rocket fuel, just like standing on a skateboard and playing catch with a bowling ball...the way you do.
5.Because of all the ash and ejecta that was pumped into the atmosphere from the crash, the earth would enter into a deep years-long nuclear winter where temperatures around the world would be freezing without any other seasons.
