I asked Gemini AI to review this video.

Gemini 3 Pro Thinking -
*Summary*

The video argues that the incompatibility of QM and GR isn't just a matter
of finding the right "graviton" particle; it is a deep logical conflict
where the *linearity of QM forbids the non-linear vacuum structures
required by GR*. Gorard suggests that advanced mathematics,
specifically *Infinity
Category Theory*, might be the necessary language to unify them.

----------------------

I then asked Gemini  - Could the multiverse solve this conflict?

Gemini 3 Pro Thinking -

Based on the video and the views of the physicist discussed (Roger
Penrose), the short answer is: *No, Penrose actually uses this argument to
try to disprove the multiverse.*

*Summary*

   -

   *Penrose:* The conflict proves the Multiverse is impossible; gravity
   destroys the other branches.
   -

   *Gorard/Modern Theory:* The conflict might be solved by redefining
   "time" using Higher Category Theory, which could allow a Multiverse to
   exist mathematically.

This video is relevant because it details the specific "illegal
superposition" argument Penrose uses to attack the concept of a quantum
multiverse in the presence of gravity.
