  1. Is there a question? What are N, x, y?
  2. I hate to say this, but it sounds like meaningless wordplay.
  3. mereotopological - Did you invent this word? What does it supposed to mean?
  4. I agree with Fermi. Interstellar distances are a the main problem.
  5. Define numbers. As is the question doesn't make sense.
  6. I know very little about this subject. However movement like this usually means they need more room.
  7. Could you summarize? Is there a question?
  8. Science fiction is your best bet.
  9. Whenever I write a sum in Latex, the limits appear forward of the sum sign. I have seen many instances where the limits are below and above. What is the code to get them there?
  10. Make up a definition. Will it be meaningful?
  11. Any description beyond current expansion from the big bang is pure speculation.
  12. Mathematics is flexible. You can define such concepts, such as negative dimension or sets with a negative number of elements and do what you want with them. It would be very hard to give them any physical meaning.
  13. The notation is math, mot physics. https://en.wikipedia.org/wiki/Christoffel_symbols
