The physicist in me don't know. But he likes the universal equation of  
the multiverse E = 0, in which physical time disappear globally.
The computationalist does not even know if there is space .... I got  
just the shadow of the shadows of braids and perhaps knots. I dream  
about a rich quantum universal topology.

Some things which are only in the mind could really exist, once you  
accept that mind exists.

All I say is that if MEC is true (in the coginitive science, or in  
theology ...) then those things (space, time, energy) emerge from what  
numbers can tell about numbers. I will be able to say more if I get to  
the AUDA (the Arithmetical version of the UDA) where things are more  
precise.

I am not suggesting a new physics, I just make a point in "theology":  
if we are machine, the theory of matter will be a modality on  
arithmetic. A numbers' view of numbers, and numbers' sequences, well  
everything representable in Robinson arithmetic, or by a universal (in  
the sense of Church Turing) immaterial (number-theoretical) machine.
