No one knows.
The second video shows why I like Greene better than Tyson.
In my opinion, Tyson's fame has generated an ego that is counterproductive in that it limits his ability to entertain any other conclusions or ideas, other than the ones he prefers..
The I'm right , you're wrong attitude, is plain to see in that video. In contrast, Brian is very open to imagining other possibilities.
I'm one that thinks there might be something missing in math. Much like before the concept of zero was added. That something, in my mind, would be something that breaks free of the linear aspect of math.
Once that something is added, and I haven't a clue what it might be, the craziness of quantum mechanics might make sense. So too the questions about multiverses.
Greene's suggestion that math might not be able to define the Universe may be correct. In my mind, not that math isn't the right tool, but that it's incomplete.
