” a huge explosion of molten matter from a meteorite of large size. the ejecta then would cool in a weightless environment. “
Why “weightless”? Lead shot is made by dropping in a tower that is in a gravity environment, It’s the gravity that makes them spherical, isn’t it?
Well, that is the first time I have ever received a reply 11 years after I made a comment! LOL....
As to your gravity assertion, you are correct that sphere shapes can be created in a environment with gravity, but it generally requires a rotational or spinning component for molten metals..or some other component to create surface tension so that the shape is formed before hardening. (has to occur pretty fast)
Taking a second look at this, it could have been under gravity or not. It could have been spinning or not and it could have been created by surface tension of the primary or second element or not.
But then I only stayed in a Holiday Inn Express one time and did not feel any smarter. In fact I have forgotten so much in my 65th year that I don’t recall if I actually stayed the night,,
So......what were we talking about..?
