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.
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.
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.
