Well, things are going pretty slow out there. Maybe there's a lot of evasive maneuvering. :-)

I’ve always wondered why this scheme does not result in a runaway chain reaction leading to a massive debris field.

            Hello out there,

            Oops this sounds sentimental. It is.

            https://www.space.com/freeman-dyson-dead-at-96.html

            Only knew him by name & fame_yet I honestly suffer he had
            to let go.

            Anybody on the list who was fortunate to talk to him in
            person? And what did her say to you?

            I did talk to a person who did, early this century. Casual
            chat it was.

            Maybe his son carries on his missive for awhile.

            Both are remembered a lot on YouTube fortunately.

            John D.
