I had this question pop into my head. Who is the going to be the new scientist go to with Stephen Hawking passing?
oddly, i did not feel close to him despite admiring him immensely. i felt a lot closer to sagan and feynman.
are you asking who will die next or who will figuratively step into his shoes?
to both questions i answer: no one can know. but i think the latter will be someone of whom we have not yet heard. and she will be great!
