Dear Prof. Dr. Fay Dowker:

I am reading about your “teacher, mentor, friend” and know with causal set theory you stood-and-cleared your own ground. Yet, with wormholes, even Maldacena, Susskind, Spiropulu and even Thorne have not been able to get much beyond Wheeler and Misner.

Elon Musk is waiting for a paper to tell him how and where to go!

If you will play with a tool model for a little, there may be another way: https://81018.com/

Can you tell me why we should or should not entertain that toy model further?

Thank you.

Most sincerely,

Bruce
